PRIORITY
Internet-facing and unauthenticated Langflow deployments should receive the highest remediation priority.
RECOMMENDATIONS
Immediate Actions
Upgrade Langflow Immediately. Upgrade affected Langflow installations from 1.0.0 through 1.12.2 to 1.12.3 or later.
Prioritize Internet-Facing Deployments. Immediately identify Langflow instances accessible from the Internet or other untrusted networks.
Identify Unauthenticated Access. Review whether Langflow instances can be accessed without authentication. Any publicly reachable unauthenticated deployment should be treated as a critical exposure.
Review Application Secrets. After remediation, review secrets, API keys, credentials and other sensitive configuration accessible to affected Langflow instances.
Rotate Potentially Exposed Credentials. Where compromise is suspected, rotate potentially exposed credentials, API keys and tokens.
Review Logs for Exploitation. Investigate Langflow and host-level logs for suspicious requests, unexpected processes and unusual network activity.
Restrict Network Exposure. Where immediate patching is not possible, restrict access to Langflow from untrusted networks.
Validate Remediation. Confirm that the affected Langflow instances are running the fixed version after remediation.
SOC HUNTING
SOC Hunting Priorities
Hunting Area
What to Investigate
Web Requests
Suspicious or unexpected requests targeting Langflow endpoints.
Process Creation
Shells, scripts or unexpected processes spawned by Langflow.
Command Execution
Unexpected command-line activity associated with the Langflow process.
Network Connections
Unexpected outbound connections from Langflow hosts.
File Activity
Unexpected file creation, modification or execution.
Credentials
Access to API keys, tokens or application secrets.
Persistence
New services, scheduled tasks, startup entries or other persistence mechanisms.
Authentication
Unexpected access to Langflow instances, especially unauthenticated activity.
INCIDENT RESPONSE
Incident Response Considerations
Because the two critical vulnerabilities reportedly allow unauthenticated remote code execution, organizations should not assume that patching alone resolves the risk if an affected Internet-facing instance may already have been compromised.
For potentially exposed systems, security teams should consider:
Reviewing historical Langflow access logs.
Investigating unexpected processes spawned by the Langflow application.
Checking for newly created files or persistence mechanisms.
Reviewing outbound connections from the Langflow host.
Rotating potentially exposed API keys, credentials and secrets.
Assessing connected databases, APIs and cloud services for suspicious activity.
Preserving relevant logs and forensic evidence where compromise is suspected.
RISK ASSESSMENT

URGENT WARFARE ADVISORY
Strategic Threat
Intelligence
Iranian Cyber Warfare
Escalation: Industrialized Cyber Conflict Enters a New Phase
Status: Under Escalation
Prepared by: CyberShelter Threat Intelligence
Period: Feb 28 2026 – Present
EXECUTIVE OVERVIEW
Industrial-Scale Cyber Warfare
Since February 28 2026, Iranian cyber operations have transitioned from reactive retaliation into what
can now be classified as industrial-scale cyber warfare, combining destructive cyberattacks,
supply-chain compromise, infrastructure targeting, and multi-state threat collaboration.
Latest intelligence shows a clear evolution in attack sophistication, operational scale, strategic
targeting, and the weaponization of legitimate enterprise tools. This marks one of the most
aggressive cyber escalation phases observed in recent history.
KEY DEVELOPMENTS
Cyber-Physical & Enterprise Escalation
1. Destructive Enterprise Attacks Using Trusted Platforms
Shift toward abusing enterprise management systems rather
than deploying traditional malware.
Case Study: Stryker MDM Wipe Attack Attackers weaponized Microsoft Intune
administrative controls to destroy approximately 200,000 devices across 79 countries within three
hours.
Why this matters: This demonstrates a major shift from
traditional ransomware to Living-off-the-land techniques, admin platform abuse, identity
compromise, and management plane attacks. Identity security is now more critical than
endpoint security.
Iran-linked operations targeted cloud infrastructure facilities (Data Centers, Cloud Regions) in the
Middle East, disrupting banking systems, enterprise cloud workloads, financial platforms, and
ride-hailing applications. This marks one of the first known examples of cloud infrastructure becoming a
geopolitical battlefield.
Strategic Shift: Attack focus expanded from Networks, VPNs, and Industrial systems to
include Cloud regions, Data centers, SaaS ecosystems, and DevOps pipelines. This signals a transition
toward digital supply chain warfare.
3. Expansion of Iranian Threat Actor Ecosystem
Iranian cyber operations expanded from 6 major groups to more than 10 active threat actors, specifically
targeting telecom, aerospace, and maritime sectors. Key actors include:
Void Manticore (Handala)
MuddyWater
Cotton Sandstorm / Charming Kitten
CyberAv3ngers / ShroudedSnooper
Dust Specter
EXP
Expansion Indicators
More malware families, targeting diversity,
cross-nation collaboration, faster operational tempo.
OPS
Operational Evolution
AI-assisted phishing, RMM abuse, supply-chain
poisoning, infrastructure pre-positioning. (Indicates structured cyber military organization
rather than isolated activity).
4. Supply Chain Attacks becoming a Primary Weapon
Attackers targeted developer ecosystems (npm, Docker, GitHub tokens, CI/CD, AI tooling). A single
campaign cascaded across multiple platforms within days, showing the growing risk of software trust
exploitation.
Key Insight: Supply chain attacks now provide attackers with maximum scale,
minimal detection risk, long persistence, and mass credential harvesting. Software
dependencies are the new attack perimeter.
5. Surveillance Infrastructure Exploitation
Increased exploitation of Hikvision and Dahua cameras for intelligence gathering, military targeting, and
physical surveillance. This marks a dangerous evolution toward cyber-enabled kinetic
targeting.
STRATEGIC TREND ANALYSIS
Major Attack Trends Identified
T1
Management Plane Attacks
Targeting MDM platforms, Identity systems, Firewall
controllers, and Cloud admin accounts. Goal: Control the control systems.
T2
Identity Over Exploits
Credential abuse is replacing zero-days. More reliable,
lower cost, and harder to detect.
T3
Multi-State Exploitation
Conflict exploited by Russia, China, Belarus, and
Hamas-aligned actors. Result: A global cyber opportunistic environment.
T4
AI Integration
Phishing, social engineering, and profiling. AI is
accelerating attack scale rather than replacing attackers.
Trend 5 — Destructive Intent Increasing: Growth in wipers, data destruction, and
infrastructure disruption, shifting from espionage toward systemic disruption.
Reality 1: Cyber warfare is now continuous, not event-driven. Reality
2: Enterprise software is now battlefield infrastructure. Reality 3:
Identity is the new security perimeter.
Critical Assumption: Future cyber conflicts will target business infrastructure
first, not governments.
CyberShelter Verdict: Organizations should immediately validate Identity security
posture, MDM/UEM controls, Backup resilience, Supply chain exposure, and RMM usage. The next phase will
focus on scalable enterprise disruption.
Final Conclusion: The cyber escalation observed since February
28 2026 demonstrates a new cyber warfare model defined by industrialized operations, infrastructure
targeting, identity compromise, and supply chain warfare. Geo-political risk must now be treated as a
continuous operational threat rather than a theoretical scenario.

VULNERABILITY ANALYSIS 1
Critical Telnetd Vulnerability (CVE-2026-32746)
Technical Overview
A critical buffer overflow vulnerability has been discovered in the GNU InetUtils Telnet daemon affecting
all versions up to version 2.7. The vulnerability exists due to an out-of-bounds memory write in the
LINEMODE SLC handler. This flaw occurs during Telnet option negotiation before authentication.
Buffer Overflow
Vulnerability Type
None
Authentication Required
Root
Default Privilege Level
Attack Mechanism
The vulnerability can be exploited without user interaction:
Attacker connects to Telnet port 23
Sends specially crafted SLC negotiation packets
Memory corruption occurs
Arbitrary memory writes become possible
Remote code execution achieved
Because Telnet often runs as root, successful exploitation equals full system takeover. Low exploit
complexity makes this highly dangerous.
Potential Impact
Install persistent backdoors
Steal sensitive data
Move laterally across networks
Deploy ransomware
Establish command and control access
Pivot deeper into infrastructure
VULNERABILITY ANALYSIS 2
Active Cisco FMC Zero-Day Exploitation (CVE-2026-20131)

CRITICAL ADVISORY
Destructive Malware Advisory
Threat Advisory: Rising
Risk of Wiper Malware Attacks
CyberShelter Threat Intelligence has observed an increase in destructive cyberattacks involving wiper
malware, a class of malware designed to permanently destroy data and disrupt business operations. Unlike
ransomware, wipers focus on irreversible damage rather than financial gain.
Recent threat actor campaigns show increasing use of supply chain compromise, credential abuse,
living-off-the-land techniques, and backup destruction tactics. Organizations must prioritize cyber
resilience and rapid recovery capabilities alongside prevention.
THREAT ANALYSIS
What is Wiper Malware
Wiper malware is a destructive cyber weapon used to delete critical files, corrupt operating systems,
destroy Master Boot Records (MBR), delete shadow copies and backups, and disable security tools. Impact
often includes complete operational shutdown, massive data loss, significant incident recovery costs,
and reputational damage.
!!
Irreversible Damage: Focuses on permanent destruction rather than financial
gain.
!!
Business Disruption: Designed to halt operations and maximize recovery time.
Backup Protection: Maintain offline and immutable backups with separate
credentials.
04
Vulnerability Management: Risk-based patching focusing on internet-facing
systems.
CONCLUSION
CyberShelter Protection Approach
Destructive attacks such as wiper malware are increasing and organizations must shift from
prevention-only strategies to resilience-focused security models combining detection, response, and
recovery readiness.
Recommended Action: Conduct a Destructive Attack Readiness Assessment covering
detection, backup resilience, and recovery maturity.
CyberShelter's Threat Intelligence team has recently identified a set of suspicious Indicators of
Compromise (IOCs) associated with potentially malicious infrastructure hosted on cloud platforms. The
activity suggests possible malware staging, payload delivery, or command-and-control (C2) preparation
leveraging trusted cloud services to evade traditional security controls.
During ongoing threat monitoring activities, suspicious domains and URLs were identified within Microsoft
Azure environments. Attackers increasingly abuse reputable cloud providers to blend malicious traffic
with legitimate enterprise traffic.
Based on initial analysis, the infrastructure shows characteristics commonly associated with malware
delivery, living-off-trusted-cloud techniques, and data exfiltration (upload path observed).
!
Reputation Abuse: Azure is trusted by enterprise networks, making blocking
difficult.
!
Encryption: TLS encryption hides payload delivery from traditional inspection.
MITIGATION
Recommended Mitigation Actions
01
Network Security: Block identified domains/URLs and monitor outbound
connections to Azure app services.
02
Endpoint Security: Block listed hashes and perform threat hunting for
processes spawning from downloaded executables.
03
SOC Actions: Search SIEM/Proxy logs for communication with rare Azure
subdomains.
CONCLUSION
CyberShelter Protection Approach
This investigation remains ongoing. Organizations should treat these indicators as high-confidence
suspicious infrastructure until proven otherwise and take proactive preventive action.
Continuous Monitoring: CyberShelter recommends implementing a proactive defense
strategy combining EDR, Zero Trust network principles, and cloud activity monitoring.
Void Manticore (Handala) represents one of the most dangerous active Iran-linked destructive cyber actors
currently targeting the UAE. Their ability to combine wiper attacks, influence operations, and
infrastructure disruption makes them a significant strategic threat.

disruption
EXECUTIVE SUMMARY
Escalation to Destructive Operations
CyberShelter Threat Intelligence has observed a significant escalation in hacktivist cyber activity
across the Middle East between March 7 and March 12 2026. Threat actor activity evolved rapidly from
disruptive operations such as Distributed Denial-of-Service (DDoS) attacks and website defacements into
more serious incidents including destructive attacks, data breaches, and supply-chain disruption
campaigns.
A key development during this period was the Stryker Corporation incident, which demonstrated a new
willingness among Iran-aligned actors to conduct large-scale destructive attacks against global
commercial supply chains.

URGENT THREAT ADVISORY
LIVE CONFLICT ENVIRONMENT - Op.
Epic Fury / Roaring Lion
1. SITUATION OVERVIEW - UAE UNDER ACTIVE CYBER TARGETING
Current Threat Posture
INTELLIGENCE ASSESSMENT: UAE-based organisations face an elevated, multi-vector Iranian
cyber threat across three operational layers simultaneously: (1) hacktivist/proxy DDoS and defacement
campaigns running now; (2) pre-positioned MuddyWater/Seedworm espionage implants in UAE networks that
could pivot to destructive operations; and (3) state-directed IRGC/MOIS wiper and ransomware campaigns
that will intensify as Iran's conventional military options are degraded. BeyondTrust, Unit 42, and
Cisco Talos all assess the next 14-30 days as the highest-risk window.
2. GEOPOLITICAL CONTEXT - WHY UAE IS IN THE CROSSHAIRS
Targeting Logic
Understanding Iran's targeting logic is essential for UAE organisations to accurately assess their own
risk profile.
Target Category
Risk Logic
UAE's Role
Hosts US military facilities; F-35 basing and logistics support for Operation Epic Fury;
intelligence sharing; US CENTCOM forward presence
Abraham Accords
UAE-Israel normalisation (2020) makes UAE a declared target in Iran's political framing;
economic, technology, and defense cooperation directly cited in Iranian threat actor
manifestos
Financial Hub Risk
UAE financial institutions (major financial hubs and banking institutions) process regional
transactions; disruption has asymmetric geopolitical impact
Energy Sector
UAE oil and gas infrastructure (critical energy production facilities) is a standing target for Iranian
ICS/OT-capable groups including CyberAv3ngers and APT33
Aviation Nexus
DieNet specifically targeted UAE airports; Sylhet Gang-SG targeted Abu Dhabi Civil
Defense; aviation disruption is a stated Iranian objective
Supply Chain Role
UAE's position as a re-export hub and supply chain conduit makes it a second-order
target - disrupting UAE logistics impacts Israel and US operations regionally
Diaspora Data
APT34/35/39/42 are actively harvesting population-scale data from ISPs, medical systems,
and telecoms to identify Iranian regime dissidents - UAE's Iranian diaspora makes local
ISPs and telecoms priority targets
3. IRAN'S THREAT ECOSYSTEM - ACTORS TARGETING UAE
Actors Currently Targeting UAE
Iran's offensive cyber capability is distributed across two primary state bodies and an extended
ecosystem of proxy hacktivist groups. Understanding this structure is critical because the two state
bodies have different mandates, TTPs, and escalation patterns.

4. WIPER & DESTRUCTIVE MALWARE - ACTIVE IN CURRENT CONFLICT
Active Wipers in Current Conflict
The following wiper and destructive malware families are confirmed active in the current Iran conflict,
deployed by groups that have either directly targeted UAE or have UAE within their stated or
demonstrated targeting scope.
DIRECT UAE RISK: Void Manticore has confirmed targeting of UAE as part of its Gulf
operations. The Stryker attack (11 Mar 2026) used Microsoft Intune MDM to wipe 200,000+ devices. Any
UAE organisation using a Microsoft Intune-managed device estate with weak administrative account
controls is directly at risk from this attack pattern.
Wiper Name
ZeroShred (Void Manticore / Handala)
Attack Method
Spear-phishing ? credential theft ? Microsoft Intune MDM console compromise ? mass
remote wipe command to all enrolled devices
Targets storage devices of Israeli critical infrastructure; wipes/disables storage
making recovery impossible
SewerGoo
Companion to BlueWipe; same Israeli critical infrastructure campaign; storage
destruction focus
BeepFreeze
Deployed against Albanian government networks; demonstrates Iran's willingness to use
wipers against non-Israeli targets including Gulf-region allies
Relevance to UAE
Pattern of geographic expansion mirrors the current conflict escalation;
BlueWipe/SewerGoo techniques applicable to any storage infrastructure
4.3 Sicarii Ransomware-Wiper (HIGH RISK UAE)
HIGH RISK - UAE REGION: Sicarii has confirmed META (Middle East, Turkey, Africa)
regional focus including UAE. The malware destroys its own decryption keys - making any 'ransom'
payment pointless. This is effectively a wiper disguised as ransomware.
Type
RaaS (Ransomware-as-a-Service) with inherent wiper behaviour
Encryption Flaw
Discards decryption keys after encrypting - victims permanently lose data regardless of
payment
Geographic Focus
META region with US entities; UAE confirmed in targeting scope
Emergence
December 2025; surging activity since Feb 2026 kinetic escalation
Monitoring
Halcyon RRC actively tracking; linked to broader Iran-aligned hacktivist ecosystem
Wiper disguised as ransomware; ransom note displayed but decryption impossible by design
Tools Used
DEADWOOD wiper; Apostle (pseudo-ransomware); Fantasy wiper
UAE Relevance
Agrius was among the FIRST Iran-linked actors to target Emirati entities alongside
Israeli ones; long-standing UAE targeting history
Initial Access
Exploits internet-facing web servers; uses commercial Israeli VPN infrastructure as
launch point
Goal
Maximum psychological impact + data destruction; narrative control via fake ransomware
framing
5. OPERATION OLALAMPO - MUDDYWATER ACTIVE IN UAE (LIVE CAMPAIGN)
Live Campaign Analysis
CONFIRMED UAE TARGETING: Operation Olalampo is an active MuddyWater campaign that has
confirmed UAE organisations among its victims. Exposed C2 infrastructure analysis by the Ctrl-Alt-Intel
collective identified UAE companies in victim telemetry alongside Israeli, Jordanian, Egyptian, and US
entities.
Operation Olalampo represents a significant evolution in MuddyWater's technical capabilities, first
observed 26 January 2026 and accelerating post-28 February conflict escalation.
Attack Chain:

9. THREAT HUNTING PRIORITIES FOR UAE SOC TEAMS
Immediate UAE SOC Hunts
Based on confirmed MuddyWater UAE compromises and the Olalampo campaign C2 infrastructure exposure, the
following hunting queries should be run immediately on your UAE client environments:
Hunt ID
Query Description
Why / Relevance
H-001
Search EDR telemetry for any process making outbound connections to codefusiontech[.]org or 18.223.24[.]218
Confirmed MuddyWater Olalampo C2 - any hit confirms active infection
H-002
Look for deno.exe execution in your environment - especially spawned by Office or
dropped in temp directories
DinDoor BYOR backdoor; Deno is unusual in enterprise environments outside dev
workstations
H-003
Search for rclone.exe usage with cloud storage destination arguments (wasabi, backblaze)
on non-sanctioned endpoints
MuddyWater exfiltration pattern - if found, treat as active data breach
H-004
Query Intune audit logs for any bulk device actions (wipe, retire, reset) in the past 90
days - baseline normal
Establish legitimate wipe activity baseline BEFORE an attack occurs; anomalies will be
detectable only against this baseline
H-005
Search for Office processes spawning PowerShell with Base64-encoded commands or -enc
flag in past 30 days
Olalampo macro delivery pattern; may reveal existing undetected compromises
H-006
Search DNS logs for queries to Telegram API endpoints (api.telegram.org) from
server-class machines or unexpected endpoints
CHAR Rust backdoor C2; servers have no legitimate reason to query Telegram API
H-007
Identify any Hikvision or Dahua cameras in UAE client networks; verify firmware versions
against CVE-2017-7921, CVE-2021-36260, CVE-2025-34067
Confirmed active exploitation in UAE/Gulf region right now - any unpatched camera is a
potential foothold
H-008
Search for AnyDesk installed via command line or dropped to non-standard paths (not
Program Files)
MuddyWater HTTP_VIP drops AnyDesk to take over systems; distinguishable from legitimate
AnyDesk by install path and parent process
H-009
Hunt for Rhadamanthys infostealer IOCs in email gateway / proxy logs - look for F5
update lure emails
Void Manticore / Handala pre-wiper credential harvesting; if Rhadamanthys found, wiper
deployment may follow
H-010
Query firewall/proxy for outbound connections to Ethereum RPC endpoints (infura.io,
mainnet.infura.io, etherscan.io) from non-crypto endpoints
MuddyWater EtherHiding C2 - blockchain-based C2 resolution to resist takedown; extremely
unusual for business endpoints
10. UAE-SPECIFIC HARDENING ACTIONS
Priority Actions
Actions are ordered by urgency based on confirmed attack vectors used in the current conflict. Complete
P1 within 24 hours, P2 within 72 hours, P3 within 7 days.
P1 - IMMEDIATE (Within 24 Hours)
01
INTUNE/MDM HARDENING: Enable Privileged Identity Management (PIM) for all
Intune Administrator roles. Set to Eligible (not Active). Require MFA + approval for activation.
Review all current Active Intune admin role assignments.
This directly addresses the
Stryker attack vector - the single highest-risk gap for UAE Intune-managed
organisations.
02
CONDITIONAL ACCESS: Block legacy authentication protocols to all Microsoft
365/Entra services. Require phishing-resistant MFA (FIDO2) for all admin accounts. Apply Named
Locations policy restricting admin access to UAE corporate IP ranges.
03
CAMERA AUDIT: Identify all Hikvision and Dahua cameras in your network.
Immediately patch or segment CVE-2017-7921 and CVE-2021-36260 vulnerable devices. These are
being actively scanned and exploited in UAE right now.
04
BLOCK C2 IOCs: Add codefusiontech[.]org and
18.223.24[.]218 to DNS blocklists, firewall deny rules, and proxy
category blocks. Alert on any existing outbound connections to these indicators.
05
MACRO POLICY: Enforce Group Policy or Intune policy to block all VBA macros in
Office documents from internet sources. This disables MuddyWater's primary initial access
vector.
P2 - URGENT (Within 72 Hours)
01
BACKUP VERIFICATION: Confirm you have at least one offline/air-gapped backup
of all critical systems taken within the last 24 hours. Iranian wipers target all
network-accessible storage - offline backups are the only recovery path.
02
RMM INVENTORY: Conduct immediate audit of all RMM tools installed across your
environment (AnyDesk, TeamViewer, Atera, Splashtop, etc.). Remove any not explicitly authorised.
Alert on new RMM installations.
03
EDGE DEVICE PATCHING: Prioritise patching of all internet-facing VPN
appliances, firewalls, and web servers. MuddyWater Olalampo is actively exploiting
recently-disclosed CVEs on public-facing servers.
04
INTUNE DEVICE SCOPE REVIEW: Ensure only corporate-owned, compliant devices are
enrolled in Intune. Remove personal devices. Validate wipe policies apply only to expected
device scope.
05
MONITORING BASELINE: Pull 90-day baseline of Intune audit logs, Entra sign-in
logs, and device management actions to establish normal before attempting anomaly detection.
P3 - STRATEGIC (Within 7 Days)
01
OT/ICS NETWORK SEGMENTATION: Ensure complete network isolation between IT and
OT networks. CyberAv3ngers (IRGC) has demonstrated capability and intent to attack industrial
control systems including UAE energy infrastructure.
02
SUPPLY CHAIN ASSESSMENT: Identify all business relationships, software
vendors, and service providers with Israeli connections. Per Void Manticore doctrine, any
Israeli business relationship makes an organisation a target. This is not theoretical - it is
the explicit basis for the Stryker attack.
03
WIPER TABLETOP EXERCISE: Conduct a destructive attack tabletop within 7 days.
Scenario: 'All Intune-managed devices wiped simultaneously - what are your first 15 minutes of
response?' Involve legal, comms, and executive teams.
04
THREAT INTEL SHARING: Join UAE's TRA/CIRA information sharing mechanisms.
Ensure your UAE clients have registered with UAE-CERT. Share observed IOCs with relevant
national authorities.
05
AI-PHISHING AWARENESS: Iran (MuddyWater, APT42) is deploying AI-enhanced
phishing with more convincing lures. Run targeted phishing simulation using Iranian-themed lures
(F5 update, INCD notification, flight ticket, regional news) to test current staff awareness.
If you detect wiper-related activity in a UAE client environment, execute in this order:
Time
Action
Owner
T+0
ISOLATE: Immediately network-isolate all affected endpoints. For
Intune-compromised environments: block all admin accounts from Intune portal, revoke
active sessions in Entra ID.
SOC/IR Lead
T+5 min
PRESERVE: Capture memory images (if accessible) of unaffected domain
controllers and key servers before wiper propagates further. Forensics window closes
fast.
DFIR Team
T+10 min
ACTIVATE OFFLINE BACKUP: Contact backup team to initiate recovery from
most recent offline/air-gapped backup. Do NOT attempt to restore from network-accessible
backups - these may be wiped.
IT / Backup Team
T+15 min
NOTIFY: Alert UAE-CERT ([email protected]), relevant sector ISAC, and
legal/privacy counsel. SEC/DPO notification may be required if personal data was
exfiltrated.
Legal / CISO
T+30 min
ASSESS SCOPE: Identify blast radius - how many devices affected, what
data was accessible, were backups hit? Separate IT recovery from forensic investigation.
IR + IT
T+1 hour
COMMS: Prepare internal and external communications. Handala will
likely publish a blog post claiming the attack - get ahead of the narrative. Stryker had
no public comms ready.
Comms / Legal
T+24 hours
REVIEW ACCESS PATH: For Intune-based wipe: determine how admin
credentials were obtained. Rhadamanthys infostealer is the suspected primary credential
theft vector - check email/proxy for F5 update phishing indicators.
DFIR
T+72 hours
REBUILD: Begin clean OS rebuild from known-good images. Do NOT restore
from potentially-compromised backup sets until forensically cleared.

Overview
Executive Overview
CyberShelter threat intelligence analysts have identified a targeted cyber-espionage campaign against
organizations in the UAE aerospace, defence, and government sectors. The activity is attributed with
high confidence to Peach Sandstorm (APT33), an Iranian IRGC-aligned threat group.
The campaign, tracked as CandleStone, leverages spear-phishing themed around the Abu
Dhabi Space Debate, delivering payloads via Virtual Hard Disk (VHD) containers to bypass Windows
security mechanisms.
Prior history indicates APT33 frequently transitions from espionage to destructive
operations. This campaign should be treated as a high-risk precursor to potential
disruptive attacks.
Section 01 Strategic Context

Overview
Executive Summary
CyberShelter threat intelligence monitoring indicates a sustained increase in cyber threat activity
across the Middle East driven by geopolitical tensions, particularly following regional conflict
developments beginning February 28, 2026.
Recent intelligence shows a surge in: Hacktivist operations, State-aligned cyber reconnaissance,
Ransomware activity, Infrastructure targeting claims, and Social engineering campaigns exploiting
regional tensions.
While most incidents currently remain low to medium impact disruptions, the overall threat posture
for UAE organizations remains elevated due to increased targeting narratives and opportunistic cyber
activity.

CyberShelter Defensive Recommendations
Organizations should implement immediate defensive measures.
The regional threat environment remains elevated due to the combination of Geopolitical escalation,
Hacktivist mobilization, Proxy cyber operations, and Opportunistic cybercrime.
Although most attacks currently focus on disruption and influence operations, organizations should
prepare for potential escalation. Cyber resilience now requires continuous monitoring, proactive threat
hunting, and improved defensive readiness.
Cyber activity linked to geopolitical tensions continues to demonstrate how rapidly cyber risk can
increase during regional instability. Organizations that maintain strong visibility, rapid detection
capability, and proactive defensive controls will be best positioned to withstand evolving cyber
threats.
CyberShelter NSOC continues to monitor threat developments and
provide early warning intelligence to protect organizations across the UAE and global markets,
remaining committed to supporting organizations with real-time threat intelligence and advanced
cyber defense capabilities.

Analyst Assessment
CyberShelter assesses GCC cyber activity will remain dominated by hacktivist operations driven by
geopolitical tensions. Expected near-term trends: Continued DDoS campaigns, Government targeting, Data
leak propaganda, Credential harvesting, Defacement operations.
CyberShelter Threat Intelligence has observed a significant escalation in cyber operations following the
February 28, 2026 joint US–Israel military campaign against Iran under Operation Epic Fury /
Roaring Lion. The conflict has triggered a parallel cyber war involving state actors, hacktivist groups,
and cybercriminal organizations targeting governments, financial institutions, and critical
infrastructure across the Middle East, Europe, and North America.
The disruption of Iranian IRGC command infrastructure and domestic connectivity reductions to
approximately 4% internet availability has accelerated asymmetric cyber retaliation efforts.

ATTACK CHAIN ANALYSIS
Step-by-Step Infection Flow
Stage 1 – Malicious Archive Delivery
The infection begins with phishing ZIP archives containing a malicious LNK file and a decoy government
themed image.
Example lure filenames:
?????_?????_????????_????????.png.zip
Expanding cooperation with China.zip
Algerian Ukrainian proposals for cooperation.zip
Weapons requirements for the Kuwait Air Force.zip
Stage 2 – Malicious LNK Execution
When executed, the LNK file launches PowerShell commands that connect to filebulldogs[.]com,
download the JavaScript payload (f.js), and execute the next stage loader.
The downloaded JavaScript loader performs execution of Base64 encoded PowerShell, downloads a decoy PDF
and payload archive, extracts the Rclone executable, and prepares for data theft.
Loader Obfuscation: The malware uses Windows Script Host to execute commands while
hiding activity through XOR encoding.
DATA STEALER ACTIVITY
Data Exfiltration & Targeting
After execution, attackers use Rclone version 1.70.3 to target sensitive documents and communications
data.
Files Targeted
DOC / DOCX files
PDF / TXT files
Desktop documents
Telegram session data (\tdata directory)
Intelligence Collection: The specific targeting of Telegram Desktop data suggests a
strong focus on compromising communications.
Exfiltration Method
Stolen files are uploaded to MEGA cloud storage using attacker-controlled accounts created via anonymous
onionmail services.
INFRASTRUCTURE ANALYSIS

ATTACK VECTOR ANALYSIS
Infection Chain & Compromise Details
Initial Compromise
Attackers compromised the legitimate npm maintainer account (jasonsaayman). Observed
actions include credential compromise, changing the account email to an attacker-controlled address,
unauthorized package publishing, and malicious dependency injection.
CI/CD Pipeline Bypass
Attackers successfully bypassed GitHub Actions validation, the standard release process, and expected
trusted package pipelines. This allowed malicious code to enter production releases entirely undetected.
Potential impacts include development workstation compromise, credential theft, code repository access,
and build pipeline compromise. On an enterprise level, this poses severe risks regarding CI/CD
compromise, cloud credential theft, API key exposure, and secondary software distribution poisoning.
Detection Opportunities
Organizations should immediately investigate development environments for unexpected outbound
connections, npm installation anomalies, suspicious post-installation behavior, and presence of unknown
dependencies. CI/CD pipelines should be reviewed for unauthorized package updates and unexplained build
execution modifications.
Remove the malicious package plain-crypto-js and thoroughly inspect your
node_modules directory.
Assume Compromise Protocol:
If affected versions were installed, treat the systems as actively compromised.
Organizations must immediately invoke emergency procedures:
Rotate all API keys and service tokens
Rotate SSH keys and developer secrets
Rotate associated environment credentials
Threat Hunting & Enterprise Defenses
Security teams should actively scan endpoints for the listed IoCs, investigate RAT indicators, monitor
outbound traffic, and review CI/CD logs. To prevent recurrence, implement the following security
architecture enhancements:
Development Security: Implement dependency verification, enable package signing
validation, and use SCA (Software Composition Analysis) tools.
Architecture: Apply least privilege access, enforce MFA for all maintainers, and
adopt Zero Trust principles for development environments.

Remote / Unauthenticated
Root Cause & Impact
The vulnerability exists because the /mcp_message endpoint relies on IP whitelisting instead
of authentication. Due to a design flaw, an empty whitelist is interpreted as "allow all access",
allowing any remote attacker to access administrative functions.
Attackers could gain unauthorized administrative access, control Nginx configurations, modify traffic
routing, intercept web traffic, access sensitive configs, harvest credentials, disrupt services, and
fully compromise servers. This represents a full administrative takeover risk.

Impact
Persistent compromise
Root Cause & Impact
The vulnerability exists due to a flawed cryptographic design in the backup/restore mechanism. Backup
encryption uses AES-256-CBC, but unfortunately:
Encryption key and initialization vector are exposed to the client.
Integrity metadata is encrypted with the same key.
Integrity verification is not properly enforced.
This allows attackers to modify backups and still pass verification. As a result, attackers could modify
backup archives, insert malicious configurations, deploy persistent backdoors, execute arbitrary
commands, and achieve full system compromise.
Stealth Persistence: This vulnerability is particularly dangerous because it enables
stealth persistence within the web management interface.

Unisolated backup infrastructure
Stale VPN vulnerabilities
Over-privileged contractor accounts
Defensive Lessons
Identity systems are the core target
Offline/Air-gapped backups are non-negotiable
Endpoint detection (EDR) must protect backup nodes
Phishing remains the #1 entry point
OBSERVATIONS & ANALYSIS
Additional Intelligence & Observations
Beyond the technical breach and data destruction, several critical insights highlight the true depth
and intent of this operation.
Geopolitical Signaling & Threat Messaging
The attackers positioned the operation as a preemptive warning to regional governments, indicating
that the objective extended beyond disruption. The messaging suggests an ongoing campaign, with
explicit indications that similar or escalated actions could follow.
Claimed Widespread Operational Disruption
The attackers asserted that the impact extended beyond internal systems, causing broader disruptions
affecting city-level operations and services. While not independently verified, this claim reflects
an attempt to frame the attack as national-scale disruption rather than a contained cyber incident.
Evidence of Active System Control
Evidence released by the attackers indicates:
Administrative dashboards with full system access
Storage management consoles executing live deletion operations
Backup systems marked as "wiped"
Database tables and internal records exposed
These indicators confirm direct, hands-on-keyboard activity, showing that attackers
were actively operating within compromised environments.
Real-Time Monitoring & Defensive Awareness
The exposed environments included logs, dashboards, and monitoring tools, suggesting that attackers
were not only present but also observing system activity in real time.
This implies the capability to:
track defensive responses
adapt actions dynamically
maintain prolonged control
Exposure of Operational Infrastructure Data
Evidence indicates access to structured operational and infrastructure-related data, including system
configurations and network-linked assets.
This raises concerns that the compromise extended beyond IT systems into
operational technology (OT) environments, increasing real-world risk.
Abuse of Legitimate Administrative Tools
The attack leveraged native enterprise tools and administrative consoles, rather than relying solely
on external malware.
This "living–off–the–land" approach allowed attackers
to:
blend with legitimate activity
evade detection
execute high-impact actions using trusted systems
Controlled and Targeted Data Destruction
The deletion process indicates:
manual selection of storage volumes
confirmation-based execution
structured removal of critical data
This confirms that destruction was intentional, precise, and strategically
executed, not random or automated.
DEFENSIVE RECOMMENDATIONS
Remediation & Security Recommendations
In response to the scale and sophistication of this attack, organizations should implement the
following critical security measures:
Immediate Containment Actions
Reset all privileged accounts (Active Directory, cloud admins, VPN, service accounts)
Revoke all active sessions, tokens, and authentication keys
Enable logging across all systems (cloud + on-prem)
Investigate anomalies such as: unusual admin activity, mass data access, sudden configuration
changes
Visibility is critical for early detection and response.
Threat Hunting & Incident Response
Conduct full forensic analysis of: identity systems, virtual environments, storage and backup
systems
Assume persistence and search for hidden access points
Develop and test incident response playbooks
External Threat Monitoring
Monitor attacker channels, leak sites, and dark web forums
Track potential data exposure or publication
Prepare communication and legal response strategies
Final Takeaway: This attack shows a major evolution in cyber warfare: shifting from
simple data theft to the full destruction of entire digital ecosystems.

Critical Vulnerability Advisory
Critical RCE Vulnerability Discovered in protobuf.js Library
By CyberShelter Threat Intel Team
April 18, 2026
CRITICAL — CVSS 9.4
01 // Executive Overview
Remote Code Execution via Malicious Schema Definitions
A critical vulnerability has been identified in protobuf.js, a widely adopted JavaScript implementation of Protocol Buffers used across Node.js and browser-based applications. With a CVSS score of 9.4, this flaw poses a severe risk, as it enables remote code execution (RCE) through the processing of malicious protobuf schema definitions.
Due to the library's extensive use in modern cloud-native and microservice architectures, the attack surface is exceptionally broad. Any application that processes external or dynamically loaded protobuf schemas is potentially at risk of full system compromise.
Key Insight: protobuf.js is used by millions of Node.js and browser applications as a high-performance serialization library. A single compromised schema definition can be weaponized to achieve arbitrary code execution across the entire application runtime – making supply chain hygiene and schema validation critical defensive controls.
02 // Vulnerability & Exploitation Details
JavaScript Injection via Malicious Proto Schema
9.4
CVSS Score
CRITICAL
Severity
RCE
Vulnerability Type
Root Cause
The vulnerability resides in the parsing and compilation of protobuf definitions within protobuf.js. The library fails to adequately sanitize or restrict the content of type definitions during schema processing, allowing an attacker to inject arbitrary JavaScript expressions that are subsequently evaluated within the application's runtime environment.
Exploitation Mechanism
Attackers can weaponize this flaw by following a straightforward exploitation chain against any vulnerable application processing external or user-supplied schemas:
01
Craft Malicious Schema
Attacker crafts a malicious protobuf schema file (.proto or JSON descriptor) containing JavaScript payloads embedded within type definitions.
02
Inject JavaScript Payload
Malicious JavaScript is injected into field names, type references, or other schema elements that the parser processes without sufficient sanitization.
03
Trigger Schema Processing
The target application processes the malicious schema using functions such as Type.decode(), Root.fromJSON(), or equivalent schema-loading methods.
04
Arbitrary Code Execution
The injected payload executes within the application runtime with the process's full privileges – leading to complete system compromise, data exfiltration, or backdoor deployment.
Proof of Concept: A working proof-of-concept exploit is publicly available for this vulnerability, significantly lowering the barrier to exploitation. Threat actors can immediately leverage existing PoC code against unpatched applications, making emergency patching a top priority.
03 // Affected Versions
Scope of Impact and Patched Releases
The vulnerability affects all applications using the following versions of the protobuf.js package. Both major supported branches are impacted. Upgrade immediately to the patched releases.
Branch

7.5.5
CRITICAL
Elevated Risk Profile: Applications that rely on external or user-supplied schema definitions – including microservices, gRPC-based APIs, IoT platforms, and any system that dynamically loads .proto files or JSON descriptors at runtime – are at significantly elevated risk of exploitation.
04 // Recommended Actions
Immediate Remediation and Defensive Measures
CyberShelter strongly advises immediate remediation across all environments where protobuf.js is in use. Development, staging, and production environments must all be assessed and patched without delay.
Upgrade Immediately: Update protobuf.js to version 8.0.1 (v8.x branch) or 7.5.5 (v7.x branch). Prioritize internet-facing and data-processing services.
Avoid Untrusted Schemas: Never load protobuf schemas from untrusted, user-supplied, or third-party sources that have not been cryptographically verified.
Validate and Sanitize Inputs: Implement strict schema validation and sanitization pipelines before any schema content is passed to the protobuf.js parser.
Restrict Dynamic Schema Execution: Where possible, migrate to static, pre-compiled schema definitions rather than runtime dynamic loading from external sources.
Monitor for Anomalous Behavior: Deploy runtime application monitoring (RASP) or behavioral analytics to detect unusual execution patterns that may indicate exploitation attempts.
Conduct Code Reviews: Audit all codepaths that call schema-loading and decoding functions (e.g., Root.fromJSON(), Type.decode()) to identify unsafe patterns that process unvalidated input.
05 // CyberShelter Advisory Perspective
Supply Chain Risk and Open Source Dependencies
This vulnerability exemplifies the growing threat posed by vulnerabilities in foundational open-source libraries. protobuf.js underpins countless modern applications – from microservices and gRPC APIs to cloud-native platforms and IoT devices – making this flaw a significant supply chain risk.
The availability of a public proof-of-concept dramatically accelerates the threat timeline. Organizations that delay patching should assume active exploitation attempts are occurring or imminent. The combination of a near-perfect CVSS score (9.4), broad deployment footprint, and a working PoC makes this one of the most urgent vulnerabilities of 2026.
CyberShelter Recommendation: Treat this as an emergency patch event. Immediately run npm audit across all Node.js projects to identify affected dependencies. Patch within 24 hours for internet-facing services. For environments where immediate patching is not possible, disable all dynamic or external schema loading and implement strict network-layer controls around affected services.

Vulnerability Advisory
High-Severity Authentication Bypass Vulnerability Identified in Log Management Platform
By CyberShelter Threat Intel Team
April 18, 2026
HIGH Severity
01 // Executive Overview
Authentication Bypass in Security Monitoring Infrastructure
A high-severity vulnerability has been identified in ManageEngine Log360, a widely used log management and security analytics solution. This flaw could allow unauthorized users to bypass authentication mechanisms and gain access to sensitive data and restricted system functionality through exposed APIs.
The vulnerability is particularly critical given that log management platforms sit at the core of an organization's detection and response capabilities. Compromise of these systems can fundamentally undermine security visibility and trust boundaries.
Key Insight: Authentication bypass vulnerabilities on security monitoring platforms represent a compounding risk – attackers gain not only unauthorized access but also the ability to suppress alerts, delete evidence, and blind an organization's entire threat detection capability.
02 // Vulnerability Details
CVE-2026-3324: Improper Authorization in V1 APIs
HIGH
Severity Level
CVE-2026-3324
CVE Identifier
Auth Bypass
Vulnerability Type
Root Cause Analysis
The vulnerability arises from improper authorization checks within exposed V1 APIs in ManageEngine Log360. Due to this weakness, an attacker may be able to bypass authentication controls entirely and interact with the system without valid credentials.
The exposed API endpoints fail to enforce consistent authentication validation, creating a logic gap that allows unauthenticated requests to reach sensitive backend functionality. This type of broken access control is a fundamental security design failure that cannot be mitigated through network controls alone – the underlying code must be patched.
Attack Vector: The vulnerability is exploitable remotely over the network without prior authentication, requiring no user interaction. An attacker with network access to the Log360 management interface can leverage exposed V1 API endpoints to execute restricted operations.
03 // Affected Versions
Scope of Impact and Fixed Versions
The following ManageEngine Log360 build versions are confirmed to contain the authentication bypass vulnerability. Organizations running any build within the affected range must upgrade immediately.
Product
Affected Build Range
Fixed Version
Action Required
ManageEngine Log360
Build 13000 to 13013
Build 13017 or later
Upgrade Immediately
Potential Impact: If successfully exploited, this vulnerability could enable unauthorized access to sensitive log and event data, execution of restricted operations via exposed APIs, visibility into internal systems and security events, potential manipulation or deletion of logs, and increased risk of undetected malicious activity within the environment.
04 // Recommended Actions
Defensive Strategies and Remediation Steps
CyberShelter strongly recommends the following immediate and ongoing actions for all organizations running ManageEngine Log360:
01
Upgrade Immediately
Upgrade ManageEngine Log360 to build 13017 or later. This is the highest priority action and should be treated as an emergency patch deployment.
02
Restrict and Monitor API Access
Restrict network-level access to Log360's management interface and V1 API endpoints. Implement IP allowlisting and firewall rules to limit exposure.
03
Implement Additional Authentication Controls
Layer additional authentication and access controls (MFA, reverse proxy authentication) in front of the Log360 management interface as a compensating control.
04
Conduct API Exposure Review
Perform a thorough review of all exposed API endpoints and configurations to ensure no other endpoints bypass authentication or authorization controls.
05
Monitor for Unauthorized API Activity
Immediately enable monitoring and alerting for suspicious or unauthorized API activity targeting Log360 endpoints, particularly V1 API calls from unexpected sources.
06
Validate Log Integrity
Conduct a forensic review of recent log entries and historical data to validate integrity – check for signs of tampering, deletion, or unauthorized data access that may have occurred prior to discovery.
From a CyberShelter threat intelligence standpoint, authentication bypass vulnerabilities represent a high-impact risk, particularly when they affect security monitoring platforms. Attackers increasingly target logging and visibility tools to evade detection, remove traces of malicious activity, and gain insight into an organization's defensive mechanisms.
Evade Detection: Disabling or manipulating logging prevents security teams from identifying ongoing intrusions or lateral movement within the network.
Remove Evidence: Log deletion or modification eliminates forensic artifacts that would be critical in incident response and attribution.
Intelligence Gathering: Access to log data provides attackers with a detailed map of internal systems, user behaviors, and existing security controls – intelligence that significantly enhances subsequent attack phases.
Blind Security Teams: Compromising SIEM and log management platforms directly neutralizes the organization's ability to detect, alert on, and respond to threats in real time.
This highlights the critical need for defense-in-depth, where even internal security tools are continuously monitored, hardened, and validated. Security infrastructure must itself be treated as a high-value attack target and protected accordingly – including patching, access control, and behavioral monitoring of the tools themselves.
CyberShelter Recommendation: Organizations should apply this patch within 24 hours of identification. Until patching is complete, restrict all external and internal access to Log360's API surface and initiate a retroactive log integrity audit to detect potential unauthorized access.

IMPACT ANALYSIS
Potential Impact
Successful exploitation of these vulnerabilities could result in a range of high-impact outcomes across affected ChromeOS devices. The integrated browser-OS architecture means a single compromised web session can cascade into full OS-level compromise.
Arbitrary Code Execution
Use-after-free and heap buffer overflow vulnerabilities in components such as Blink, WebCodecs, and WebGL can be chained to gain remote code execution within the renderer process. A renderer escape combined with a kernel-level privilege escalation could result in full system compromise.
System-Level Compromise
Memory corruption flaws – particularly those affecting the Font engine and Navigation subsystem – can be exploited to corrupt critical data structures, destabilize the OS, or execute attacker-controlled payloads at elevated privilege levels.
Unauthorized Data Access
Out-of-bounds read vulnerabilities in CSS parsing and WebCodecs processing may expose sensitive memory contents, including credentials, session tokens, or decrypted data cached by browser and OS components.
Browser & OS Security Bypass
Insufficient input validation in the Navigation subsystem and inappropriate implementation in WebGL could allow attackers to bypass security restrictions such as origin policies, sandbox boundaries, or permission checks – particularly when combined with malicious web content.
Denial-of-Service & Crashes
Several memory corruption vulnerabilities, if triggered without controlled exploitation, can result in application crashes, OS-level instability, or complete device unavailability – impacting endpoint productivity and continuity.
⚠ Elevated Risk for Enterprise Fleets: ChromeOS devices in corporate, education, and government environments share centrally managed update policies. Unpatched devices – particularly those on older LTS channels – remain persistently exposed until administrator-pushed updates are applied and devices are restarted.
FIXED VERSION
Patched Release Information
Organizations and individuals should verify their ChromeOS devices are running the following minimum version:
Channel

Observed that OpenSSL has released security updates
addressing 14 vulnerabilities across supported branches.
The most severe issue, CVE-2026-84782, is a High-severity
vulnerability in DTLS retransmission handling that can
disclose heap memory to a peer or cause a denial-of-service
condition.
The remaining vulnerabilities primarily affect DTLS,
QUIC, X.509 processing, cryptographic operations and
protocol-processing components. Depending on the affected
component and deployment configuration, exploitation may
result in memory disclosure, denial of service, resource
exhaustion, timing side-channel exposure or other
security-impacting conditions.
OpenSSL published the security fixes on 29 September 2026.
Organizations using affected OpenSSL branches should
identify vulnerable deployments and upgrade to the
appropriate fixed release.
KEY RISK
Primary Security Concern
CVE-2026-84782

TECHNICAL DETAILS
Vulnerability Overview
OpenSSL has released security updates addressing 14
vulnerabilities across supported branches. The issues
span DTLS, QUIC, X.509 processing, cryptographic
operations and protocol handling.
The highest-severity issue is CVE-2026-84782, which affects
DTLS retransmission handling. Under specific conditions,
a suspended handshake write and a subsequent retransmission
can cause the retransmission logic to use a stale buffer
position.
This can result in data being read beyond the intended
message buffer. Depending on memory layout and runtime
conditions, a remote peer may receive heap memory contents
as plaintext handshake data or the affected process may
crash.
OpenSSL also addressed a use-after-free issue in the X.509
Extension Cache in OpenSSL 4.0, as well as vulnerabilities
involving QUIC resource handling, CPU consumption,
amplification accounting, memory allocation, protocol
validation and cryptographic timing behavior.

CYBERSHELTER THREAT ADVISORY
HIGH | LOCAL PRIVILEGE ESCALATION
CrowdStrike FalconFlank
Published: 05 September 2026
|
Affected Technology: CrowdStrike Falcon Sensor for Windows
01 | EXECUTIVE SUMMARY
FalconFlank Zero-Day May Enable SYSTEM-Level Privilege Escalation
A newly disclosed zero-day vulnerability, known as
FalconFlank, reportedly affects the
CrowdStrike Falcon Sensor for Windows.
The vulnerability targets Falcon's Microsoft Office malicious
and suspicious macro remediation functionality and may allow
a locally authenticated attacker with an existing foothold to
escalate privileges to NT AUTHORITY\SYSTEM.
According to the reported proof of concept, exploitation has
been demonstrated against fully updated
Windows 11 25H2 and
Windows Server 2025 systems running
CrowdStrike Falcon.
CrowdStrike is investigating the reported vulnerability and
has issued interim mitigation guidance for customers.
CrowdStrike has advised customers to disable the
Microsoft Office File Suspicious Macro Removal
Windows policy setting while keeping
Cloud Anti-malware for Microsoft Office Files
enabled. :contentReference[oaicite:1]{index=1}
KEY SECURITY CONCERN
Endpoint security software operates with highly privileged
access. Abuse of a security product's remediation mechanism
could potentially allow an attacker who already has local
execution to obtain SYSTEM-level privileges
and further compromise the endpoint.
02 | THREAT PROFILE

Threat Level
HIGH
Threat Type
Local Privilege Escalation
Affected Technology
CrowdStrike Falcon Sensor for Windows
Vulnerability
FalconFlank
CVE
Not assigned at the time of reporting
Reported Impact
Privilege escalation to NT AUTHORITY\SYSTEM
Initial Access Requirement
Existing local code execution or foothold
Remote Exploitation
Not reported as a remote unauthenticated vulnerability
This is not reported as a remote unauthenticated
vulnerability. An attacker would generally require
an existing foothold or the ability to execute code locally
before attempting to exploit the privilege escalation
technique.
However, if successfully exploited, FalconFlank could
significantly increase the impact of an existing endpoint
compromise by allowing an attacker to transition from
lower-privileged execution to
SYSTEM-level access.
ATTACK REQUIREMENT
The reported attack requires local execution on the
affected Windows endpoint. It should therefore not be
characterized as a direct Internet-facing remote
compromise.
04 | POTENTIAL IMPACT
Security Impact
Successful exploitation could allow an attacker to:
Escalate from a low-privileged account to
NT AUTHORITY\SYSTEM.
Execute commands with the highest Windows privileges.
Potentially tamper with or interfere with endpoint
security controls.
Establish persistence on compromised systems.
Access sensitive files, credentials and system resources.
Facilitate additional post-exploitation activity and
lateral movement.
Increase the overall impact of an existing malware or
intrusion campaign.
WHY THIS MATTERS
The elevated privileges associated with endpoint security
software make vulnerabilities in remediation and protection
mechanisms particularly sensitive.
05 | IMMEDIATE MITIGATION
Immediate Actions for CrowdStrike Customers
01 | Disable Suspicious Macro Removal
Based on CrowdStrike's current guidance, temporarily
disable the
Microsoft Office File Suspicious Macro Removal
Windows policy setting.
This is the specific functionality identified in the
current mitigation guidance. :contentReference[oaicite:2]{index=2}
02 | Keep Cloud Anti-malware Enabled
Do not disable the Cloud Anti-malware for Microsoft
Office Files setting.
CrowdStrike has stated that customers remain protected
through this capability when the suspicious macro removal
functionality is disabled. :contentReference[oaicite:3]{index=3}
03 | Review Falcon Prevention Policies
Verify that Falcon prevention policies are configured
according to CrowdStrike's recommended best practices.
Security teams should ensure that disabling the affected
remediation functionality does not result in broader
security policy gaps across protected endpoints.
04 | Strengthen Microsoft Office Macro Controls
As an additional compensating control, organizations
should strengthen Microsoft Office macro restrictions
through Group Policy, including:
Block macros from files originating from the Internet.
Restrict macro execution to trusted locations and
signed content where operationally feasible.
Review existing Office Trust Center policies.
Monitor attempts to execute suspicious or unexpected
Office macros.
05 | Monitor Falcon Sensor Activity
SOC teams should investigate unusual activity involving
Falcon Sensor processes, particularly:
Unexpected cmd.exe or
powershell.exe execution.
Unusual DLL loading.
Unexpected child-process creation.
Low-privileged processes resulting in SYSTEM-level
execution.
Unexpected modifications to Office documents or
remediation-related paths.
Attempts to modify or interfere with security
software.
Endpoint telemetry should be correlated with Windows
security events, process creation logs and EDR telemetry.
06 | Monitor CrowdStrike Security Guidance
Organizations should continuously monitor the
FalconFlank Tech Alert available through
the CrowdStrike Support Portal.
Do not re-enable the affected macro removal setting
solely because the initial mitigation has been applied.
The setting should only be restored after CrowdStrike
confirms that an appropriate sensor-side fix or remediation
is available and has been deployed.
06 | RECOMMENDED SOC HUNTING
Detection and Hunting Priorities
Security operations teams should prioritize hunting for
indicators associated with post-compromise privilege
escalation.
Hunting Area
What to Investigate
Process Creation
Unexpected command shells or scripting engines
spawned from Falcon-related processes.
Unexpected or unsigned DLL loads associated
with Falcon processes.
Office Activity
Suspicious Office documents followed by unusual
process execution.
Persistence
New services, scheduled tasks, registry Run
keys or startup modifications.
Endpoint Tampering
Attempts to disable, modify or interfere with
security controls.
Lateral Movement
Suspicious authentication or remote execution
following local privilege escalation.
07 | RISK ASSESSMENT
Severity: HIGH
FalconFlank presents a significant risk because the
affected functionality belongs to an endpoint security
platform operating with elevated privileges.
The primary risk is
post-compromise privilege escalation.
An attacker would generally need local code execution or
an existing foothold before attempting exploitation.
The vulnerability should therefore not be characterized
as a direct Internet-facing remote compromise.
Nevertheless, successful exploitation could transform a
lower-privileged foothold into
SYSTEM-level access, substantially
increasing an attacker's ability to disable defenses,
access sensitive resources, establish persistence and
conduct further post-exploitation activity.
The reported availability of a
public proof of concept further increases
the urgency for organizations operating CrowdStrike Falcon
on Windows endpoints. :contentReference[oaicite:4]{index=4}
Temporarily
disable the affected Microsoft Office suspicious
macro removal functionality
as instructed by CrowdStrike.
Keep Cloud Anti-malware for Microsoft Office Files
enabled.
Verify Falcon prevention policies against
vendor-recommended configurations.
Strengthen Microsoft Office macro restrictions
through Group Policy.
Prioritize monitoring of
Falcon-related process execution and SYSTEM-level
activity.
Hunt for suspicious Office documents followed by
command-shell, PowerShell or unusual child-process
activity.
Investigate any recent privilege escalation or
endpoint tampering events on Falcon-protected
Windows systems.
Closely monitor CrowdStrike security advisories
for a permanent sensor-side remediation.
Restore the affected setting
only after CrowdStrike confirms that the issue
has been appropriately addressed.
09 | CYBERSHELTER ASSESSMENT
Defensive Priority
Organizations operating CrowdStrike Falcon Sensor for Windows
should treat FalconFlank as a
high-priority endpoint security issue.
While exploitation requires local execution or an existing
foothold, successful exploitation could provide an attacker
with NT AUTHORITY\SYSTEM privileges and
materially increase the impact of an existing compromise.
Until a permanent vendor-side remediation is confirmed,
organizations should implement the recommended mitigation,
maintain compensating Microsoft Office controls, and closely
monitor endpoints for abnormal privilege escalation and
security-control tampering.
THREAT LEVEL: HIGH
Priority:
Immediate review and mitigation for organizations using
CrowdStrike Falcon Sensor for Windows.

FalconFlank represents a significant security concern because
it targets a privileged endpoint security remediation mechanism.
Although the reported exploitation requires local execution,
successful exploitation could elevate an attacker to
NT AUTHORITY\SYSTEM.
Organizations should prioritize the vendor-recommended
mitigation, maintain cloud-based Office anti-malware
protection, review Falcon prevention policies and increase
monitoring for suspicious process execution and privilege
escalation.
Security teams should continue monitoring CrowdStrike's
FalconFlank guidance for updates and should restore the
affected macro-remediation functionality only after the vendor
confirms that the issue has been appropriately addressed.
CYBERSHELTER PRIORITY: HIGH
Immediate mitigation and SOC monitoring are recommended
for organizations running CrowdStrike Falcon Sensor on
Windows endpoints.

of unauthorized access or controller compromise.
CyberShelter Assessment
Assessment
The Critical CVE-2026-70426 presents a significant
risk because exploitation could result in
code execution on the Jenkins controller.
Given the privileged role Jenkins typically plays in CI/CD
environments, compromise of a controller could expose
credentials, source code, build infrastructure, and deployment
environments.
The presence of multiple additional vulnerabilities across
Jenkins plugins further increases the attack surface.
Organizations should therefore treat this advisory as a
high-priority CI/CD security update, particularly
where Jenkins is accessible from untrusted networks.
Priority:
Immediately upgrade Jenkins Core and affected plugins, disable
or remove plugins without available fixes, restrict administrative
access, and review Jenkins environments for signs of unauthorized
activity.
