Edge Infrastructure Under Siege: Four Critical Vulnerabilities Targeting Your Network

In the span of just two weeks, critical vulnerabilities have been disclosed and actively exploited across four of the most widely deployed network edge platforms in enterprise environments: Citrix NetScaler, F5 BIG-IP, Fortinet FortiClient EMS, and Cisco IMC/SSM. Each of these flaws enables unauthenticated remote access, and three of the four are confirmed under active exploitation in the wild.

This is not a coincidence. Threat actors are systematically targeting the edge devices organizations trust most — the appliances that serve as their front door to the internet. These are the appliances and management platforms that control your network — from the perimeter devices handling remote access and VPN connectivity, to the internal management systems that govern your endpoints and server infrastructure. When they fall, the attacker doesn’t just get in. They get the keys.

Citrix NetScaler ADC & Gateway — CVE-2026-3055
CVSS: 9.3 | CISA KEV: Yes | Active Exploitation: Confirmed

On March 23, Citrix disclosed CVE-2026-3055, an out-of-bounds read vulnerability in NetScaler ADC and NetScaler Gateway when configured as a SAML Identity Provider (IDP). By March 27, just four days later, researchers at watchTowr confirmed active exploitation.

This vulnerability is being compared directly to CitrixBleed (CVE-2023-4966), the 2023 memory leak vulnerability that LockBit used to breach Boeing, The Industrial and Commercial Bank of China (the world’s largest bank), DP World, and Allen & Overy. The mechanics are similar: attackers send crafted SAMLRequest payloads to the /saml/login endpoint, triggering the appliance to leak memory contents, potentially including active session tokens, via the NSC_TASS cookie.

The exposure surface is significant. Shadowserver, a nonprofit security organization that monitors internet-facing threats and vulnerable devices worldwide, currently tracks nearly 30,000 NetScaler ADC appliances and over 2,300 Gateway instances exposed to the internet.

CISA added CVE-2026-3055 to the Known Exploited Vulnerabilities catalog on March 30 and mandated federal agencies patch by April 2, 2026.

Affected Versions & Fixes:

  • NetScaler ADC and Gateway 14.1 before 14.1-66.59
  • NetScaler ADC and Gateway 13.1 before 13.1-62.23
  • NetScaler ADC 13.1-FIPS/NDcPP before 13.1-37.262

How to determine if you’re vulnerable: Inspect your NetScaler configuration for the string add authentication samlIdPProfile. If present, your appliance is in scope.

F5 BIG-IP APM — CVE-2025-53521
CVSS: 9.8 | CISA KEV: Yes | Active Exploitation: Confirmed (Webshells Deployed)

This may be the most dangerous vulnerability on this list — not just because of its severity, but because of how long it was underestimated.

CVE-2025-53521 was originally disclosed in October 2025 as a denial-of-service vulnerability with a CVSS score of 7.5. Many organizations triaged it accordingly and deprioritized the patch. On March 28, 2026, F5 reclassified it as a pre-authentication remote code execution vulnerability with a CVSS score of 9.8 after confirming active exploitation.

Attackers are deploying webshells on compromised BIG-IP appliances, and F5 has confirmed that the webshells are operating in memory only, meaning defenders may not find clear on-disk artifacts even when compromise has occurred. F5 has also detected attackers modifying sys-eicheck, the BIG-IP system integrity checker itself, in an attempt to blind the tool designed to catch them.

The nation-state context adds urgency. In October 2025, F5 confirmed a data breach in which a “highly sophisticated nation-state threat actor” — later attributed to China — accessed BIG-IP source code and information about undisclosed vulnerabilities after spending at least 12 months inside F5’s network.

Shadowserver tracks over 240,000 BIG-IP instances exposed online. CISA ordered federal agencies to patch by March 30, 2026.

Affected Versions & Fixes:

  • BIG-IP APM 17.5.0 – 17.5.1 → Fixed in 17.5.2
  • BIG-IP APM 17.1.0 – 17.1.2 → Fixed in 17.1.3
  • BIG-IP APM 16.1.0 – 16.1.6 → Fixed in 16.1.7
  • BIG-IP APM 15.1.0 – 15.1.10 → Fixed in 15.1.11

Key IOCs to check for: Look for /run/bigtlog.pipe and /run/bigstart.ltm on disk. Check for size, hash, or timestamp mismatches on /usr/bin/umount and /usr/sbin/httpd. Review audit logs for suspicious localhost iControl REST API access.

Fortinet FortiClient EMS — CVE-2026-21643
CVSS: 9.1 | CISA KEV: Not Yet Listed | Active Exploitation: Confirmed

A critical SQL injection vulnerability in FortiClient Endpoint Management Server is under active exploitation despite not yet appearing in CISA’s KEV catalog. The flaw allows unauthenticated attackers to execute arbitrary SQL against the backing PostgreSQL database, and ultimately achieve remote code execution, via a single crafted HTTP request.

This is Fortinet’s seventh SQL-related CVE in the past 12 months, a pattern that security researchers have described as “bug whack-a-mole.” The vulnerability was introduced in version 7.4.4 through a redesigned middleware stack that failed to sanitize HTTP identification headers before passing them to database queries.

Attackers are targeting the publicly accessible /api/v1/init_consts endpoint to trigger SQL injection before authentication. Successful exploitation provides access to admin credentials, endpoint inventory, security policies, and certificates for managed endpoints. Because FortiClient EMS serves as the centralized management system for all FortiClient endpoint agents, compromise gives attackers a pivot point into the entire managed environment.

Shodan reports approximately 1,000 publicly exposed FortiClient EMS instances, with the majority in the US and Europe.

Affected Version & Fix:

  • FortiClient EMS 7.4.4 (multi-tenant mode enabled) → Fixed in 7.4.5
  • Single-site deployments are not affected
  • FortiClient EMS 7.2, 8.0, and FortiEMS Cloud are not affected

Detection guidance: Inspect HTTP traffic logs for anomalous SQL syntax in the Site header. If running version 7.4.4, assume exposure and upgrade immediately.

Cisco IMC & SSM — CVE-2026-20093 & CVE-2026-20160
CVSS: 9.8 | Patches Available | Active Exploitation: Not Yet Confirmed

Cisco has patched two critical-severity vulnerabilities affecting its Integrated Management Controller (IMC) and Smart Software Manager (SSM) On-Prem products. Both carry CVSS scores of 9.8 and enable unauthenticated remote attackers to bypass authentication or gain root access.

These vulnerabilities represent a broader pattern of Cisco management plane weaknesses that nGuard has been tracking. In the past 90 days alone, critical flaws have been disclosed across Cisco Secure Firewall (FMC), Catalyst SD-WAN, Unified Communications, and now IMC/SSM. Organizations relying on Cisco infrastructure should treat management plane security as a continuous priority.

While active exploitation has not been confirmed for these specific CVEs, the trend is clear: threat actors are targeting Cisco management infrastructure aggressively, and the time between patch availability and exploitation has compressed dramatically.

The Bigger Picture

These four advisories share a common thread that goes beyond the individual CVEs:

  • All target edge or management infrastructure — the appliances that organizations rely on for secure remote access, endpoint management, and network control
  • All are exploitable without authentication — no stolen credentials required; internet-facing exposure is the only prerequisite
  • Three of four are confirmed under active exploitation — this is not theoretical risk
  • All affect products from vendors that have faced repeated critical vulnerabilities — Citrix (CitrixBleed, CitrixBleed 2, now CVE-2026-3055), F5 (nation-state breach of source code), Fortinet (seven SQL CVEs in 12 months), and Cisco (SD-WAN, FMC, UC, now IMC/SSM)

The pattern is unmistakable: the infrastructure organizations depend on to manage and secure their environments has become the primary attack surface.

What Organizations Should Do Now

  1. Inventory and Patch Immediately: Identify all internet-facing and internally deployed Citrix, F5, Fortinet, and Cisco appliances and management systems. Cross-reference versions against the affected ranges above and prioritize emergency patching.
  2. Assume Compromise on Unpatched Systems: For F5 BIG-IP and Citrix NetScaler specifically, if patching was delayed, conduct forensic review using vendor-published IOCs before assuming the system is clean.
  3. Restrict Management Interface Access: Ensure administrative interfaces for all network appliances and management platforms are not directly exposed to the internet. Place them behind VPN or zero-trust access controls.
  4. Conduct an External Penetration Test: Validate your external attack surface. These vulnerabilities are exactly what a skilled adversary, or a competent pen tester, will find first.
  5. Review Your Vulnerability Management Program: The F5 reclassification from DoS to RCE is a cautionary tale. A vulnerability deprioritized today may be a confirmed breach vector tomorrow. Continuous scanning and re-assessment are essential.
  6. Assess Incident Response Readiness: If a perimeter appliance or internal management system is compromised, does your team know the playbook? Run a tabletop exercise focused on network appliance and management platform compromise and lateral movement scenarios.

Takeaways

Four vendors, four critical vulnerabilities, two weeks. The message is clear: your network perimeter is under coordinated assault, and the appliances you trust to protect your environment are the ones being targeted. Organizations that treat edge infrastructure patching as routine maintenance rather than an emergency response function will find themselves on the wrong side of this trend. Patch now, verify your exposure, and don’t assume yesterday’s triage decisions still hold.

Nation-State Hackers Exploit Microsoft Environments in Stryker Attack

The recent cyberattack against Stryker marks a significant shift in how attackers are compromising enterprise environments. Rather than exploiting software vulnerabilities or deploying ransomware, threat actors leveraged Microsoft cloud and identity infrastructure to execute a large-scale, disruptive attack.

This incident reinforces a growing reality: misconfigured or over-permissioned Microsoft environments can be just as dangerous as unpatched systems.

What Happened

In March 2026, Stryker experienced a widespread operational disruption after attackers gained access to its Microsoft environment. According to recent reports, the attackers did deploy malicious files and abused legitimate Microsoft tooling to carry out the attack.

After compromising administrative access, the threat actors:

  • Created or leveraged privileged accounts
  • Gained control of Microsoft Intune
  • Issued remote wipe commands to 200,000 devices across 79 countries

This resulted in:

  • Significant disruption to internal operations
  • Loss of endpoint access across the enterprise
  • Business continuity challenges across multiple regions

Notably, the attack primarily affected corporate infrastructure and operations, but also caused shipping delays that led to some patient-specific procedures being rescheduled.

Following the incident, it was reported that the FBI took action against associated hacktivist resources. And as of March 23, two weeks after the takedown, Stryker has claimed to contain the attack.

A Different Type of Attack

What makes this attack particularly important is what wasn’t used.

Attackers relied on:

  • Valid credentials or compromised identity
  • Excessive administrative privileges
  • Trusted Microsoft management tools (Intune)
  • Malicious files to hide activity

This attack reflects a hybrid approach, where adversaries combined limited malicious tooling with abuse of built-in Microsoft capabilities to blend in with legitimate activity.

Microsoft Security in Focus

In response to the incident, U.S. officials have urged organizations to strengthen security around Microsoft systems. Reporting from Bloomberg indicates that organizations were specifically advised to secure Microsoft environments and endpoint management systems following the breach. The core issue is not a vulnerability in Microsoft itself, but how the environment is configured and controlled.

This attack highlights several common gaps in Microsoft 365 and Azure environments:

  • Overuse of Global Administrator privileges
  • Lack of segmentation between administrative roles
  • Weak or inconsistent MFA enforcement
  • Insufficient monitoring of high-impact administrative actions
  • Limited visibility into endpoint management activity (Intune)

When these gaps exist, attackers don’t need to break in—they can simply log in and operate as administrators.

Broader Trend: Nation-State and Destructive Activity

The Stryker incident also aligns with a broader pattern of nation-state and politically motivated cyber activity observed in recent months. Rather than focusing solely on financial gain, threat actors are increasingly:

  • Targeting critical business operations
  • Leveraging cloud identity and management platforms
  • Conducting disruptive or destructive actions
  • Avoiding malware to reduce detection

This shift represents a move away from traditional ransomware campaigns toward operational disruption.

What Organizations Should Do Now

  1. Harden Identity & Access: Enforce MFA, reduce Global Admin privileges, and implement Privileged Identity Management (PIM).
  2. Secure Intune & Endpoint Controls: Limit high-risk actions like device wipes and review role assignments regularly.
  3. Monitor Admin Activity: Track privilege changes, new admin accounts, and bulk device actions using real-time logging and alerting.
  4. Test Incident Readiness: Run tabletop exercises to prepare for identity compromise and large-scale device disruption.
  5. Assess & Close Gaps: Perform regular configuration and risk assessments aligned to NIST, CIS, and Zero Trust principles.

Takeaways

The Stryker cyberattack makes one thing clear: if attackers control your Microsoft environment, they control your business. Even minimal malicious activity, combined with compromised identity and admin access, can drive widespread disruption. Securing identity and endpoint management is no longer optional; it’s foundational to business continuity.

Critical Cisco Ecosystem Alert: CVSS 10.0 Root Access Flaws in Secure Firewall and SD-WAN

Cisco has confirmed that a cluster of vulnerabilities within both the Catalyst SD-WAN (formerly vManage) and the Secure Firewall (ASA/FTD/FMC) ecosystems are under active exploitation or represent a severe risk to the management plane. A sophisticated threat actor, UAT-8616, has been exploiting the SD-WAN flaws since at least 2023 to gain full administrative control over network fabrics.

SD-WAN "Downgrade-to-Exploit" Tactic

The threat actor, UAT-8616, has demonstrated extreme technical proficiency by avoiding traditional malware. Instead, they utilize a "living-off-the-land" tactic:

  1. Initial Access: Exploiting CVE-2026-20127 to gain access.
  2. Persistence: Inserting a rogue peer into the management plane, effectively becoming a "trusted" part of the network.
  3. System Downgrade: Downgrading the system software to an older version.
  4. Privilege Escalation: Using the older version, exploit known root-level vulnerabilities (CVE-2022-20775).
  5. Covert Operations: Restoring the original software version to erase traces of the downgrade while maintaining root-level access.
Immediate Remediation Steps
1. Emergency Patching: There are no workarounds. Organizations must migrate to these fixed releases immediately:
  • SD-WAN: 20.9.8.2, 20.12.5.3, 20.12.6.1, 20.15.4.2, 20.18.2.1.
2. Revoke and Re-key Control Plane Trust: Immediately revoke existing vManage certificates and initiate a full re-keying of the SD-WAN control plane. If CVE-2026-20127 was exploited, rotating trust anchors is the only way to programmatically evict unauthorized "trusted" identities.
3. Threat Investigation & Forensics: Because this activity dates back to 2023, simply patching is insufficient to guarantee security.
  • Review /var/log/auth.log for suspicious "Accepted publickey for vmanage-admin" entries from unknown IPs.
  • Audit all control peering events in the web UI to ensure every peer is authorized and accounted for.
  • Investigate any unexpected system reboots or unauthorized software version changes in historical logs.
  • Have incident response services perform a deep-dive forensic analysis of your logs and system artifacts to identify if UAT-8616 has established a foothold in your network.
4. Architectural Hardening:
  • Disable HTTP for the SD-WAN Manager web UI.
  • Restrict access to ports 22 (SSH) and 830 (NETCONF) to trusted management hosts only.
  • Ensure all logging is centralized to an external, immutable server for post-event investigation.
  • Security Configuration Audits: Have your SD-WAN evaluated against security best practices to ensure no misconfigurations exist.
5. Continuous Validation:
  • Utilize Vulnerability Scanning for comprehensive and continuous visibility of your entire network ecosystem.
  • Engage in External Penetration Testing to validate that your external perimeter is resilient against the sophisticated bypass techniques used by actors like UAT-8616.
6. Identify if publicly exposed SD-WAN controllers or management interfaces can be leveraged for unauthorized entry.

The Firewall Management Center Root Access Flaws

While the SD-WAN vulnerabilities involve a "downgrade-to-exploit" cycle, the two new CVSS 10.0 flaws in the Secure Firewall Management Center (FMC) provide a more direct path to total environmental compromise. Exploitation Mechanics:

  • CVE-2026-20079 – Boot-Time Auth Bypass: This vulnerability stems from an improper system process initiated during the device boot sequence. Attackers can send specifically crafted HTTP requests to the web-based management interface. Because the flaw exists in a core system process, it allows the attacker to bypass all authentication layers and execute scripts directly on the underlying operating system with root privileges.
  • CVE-2026-20131 – Insecure Deserialization: This is a classic Java deserialization vulnerability. By sending a crafted serialized Java object to the FMC web interface, an unauthenticated attacker can trigger remote code execution (RCE). Since the FMC processes these objects with high-level permissions, the resulting execution grants the attacker full root-level control.
Immediate Remediation Steps
1. Emergency Patching: There are no workarounds. Organizations must migrate to these fixed releases immediately:
  • Secure Firewall: Consult the Cisco Software Checker for specific ASA/FTD/FMC versions addressing the March 4, 2026, disclosures.
2. Security Configuration Audits: Have your FMC configurations evaluated against security best practices to ensure no misconfigurations exist.
3. Continuous Validation:

High Impact CVE Overview

CVE ID Severity Impact Affected System
CVE-2026-20127 10.0 Critical Auth bypass in peering mechanism; remote admin access. Catalyst SD-WAN
CVE-2026-20079 10.0 Critical Auth bypass via boot-time process; allows root OS access. Secure FMC
CVE-2026-20131 10.0 Critical Insecure Java deserialization; allows RCE and root access. Secure FMC
CVE-2026-20122 5.4 Medium Arbitrary file overwrite via API (Actively exploited). Catalyst SD-WAN
CVE-2026-20128 7.5 High Information disclosure via Data Collection Agent. Catalyst SD-WAN

Beyond the Patch

While immediate patching is mandatory, it is not a guarantee of a clean environment. The "downgrade-to-exploit" methodology used by UAT-8616 in SD-WAN, combined with root-level RCE flaws in Secure FMC (CVE-2026-20079/20131) and critical SQL injection (CVE-2026-20155) and DoS (CVE-2026-20158) vulnerabilities in ASA and FTD software, creates a massive attack surface. An adversary may have leveraged these flaws to establish a persistent foothold or disrupt security enforcement prior to the update. Organizations must treat these disclosures as potential breach events rather than routine maintenance. Because these platforms serve as the "nerve center" for the entire network, rigorous forensic validation and continuous monitoring of the management and data planes are the only ways to ensure an adversary has been fully evicted from the infrastructure.

This Week in Cybersecurity (TWiC) — How Nation-States Are Speedrunning the Kill Chain

Google: state-backed actors are using Gemini across the full attack lifecycle
What happened: Google’s Threat Intelligence Group (GTIG) and related coverage describe multiple state-backed clusters leveraging Gemini for end-to-end campaign support: target research, translating and tailoring phishing content, drafting pretexts, troubleshooting scripts, and iterating on payload components when something breaks in the field. GTIG also notes interest in “agentic” workflows, prompts that try to turn the model into a repeatable operator (e.g., pseudo-auditors, “expert pentester” personas) rather than a one-off helper.

Why it matters: The biggest shift isn’t magically novel exploits, it’s throughput. When recon, lure-quality, and tooling iteration get cheaper, defenders see more tailored attempts against cleared staff, vendors, and frontline operational roles.

What to do next:

  • Tighten identity and inbox controls where “good-enough lures at scale” hurt most: MFA enforcement, conditional access, and high-signal detections for impersonation and unusual login paths.
  • Run short, frequent simulations focused on recruiter/vendor themes and “attachment-less” social engineering.

Poland’s wind/solar incident: destructive intent, OT impact, and the edge-device reality

What happened: Poland’s CERT describes coordinated destructive attacks on Dec. 29, 2025 that hit at least 30 wind and solar farms, plus other targets (including a combined heat-and-power plant and a manufacturing firm). The report frames the activity as cyber sabotage, comparing it to deliberate arson, and notes the attacks affected both IT and OT, which is still relatively rare in publicly reported incidents. Operationally, the renewables impact centered on loss of communications/visibility between facilities and distribution operators; generation continued, but CERT stresses the access level created risk of disruption at affected sites.

CISA later highlighted the same event as a warning signal for OT/ICS programs: insecure edge exposure and weak remote access hygiene remain the consistent “front door” for these outcomes.

Why it matters: DER (distributed energy resources) expands the target surface: many small sites, many vendors, uneven hardening, yet still a national resilience concern because loss of view/control is often the step before physical effect.

What to do next:

Dell RecoverPoint zero-day (CVE-2026-22769): exploited since mid-2024 with stealthy backdoors

What happened: Reporting and primary research describe active exploitation of a critical Dell RecoverPoint for Virtual Machines flaw (CVE-2026-22769), assessed at CVSS 10.0 and rooted in a hardcoded credential risk. Activity was observed since at least mid-2024 and tied to a China-nexus cluster tracked as UNC6201.

Post-compromise, investigators describe deployment of webshell/backdoor tooling and techniques aimed at staying quiet inside virtual infrastructure, precisely the kind of environment where one control-plane foothold can amplify access across many systems.

Why it matters: Backup/replication and virtualization-adjacent platforms sit in the blast radius of everything. When adversaries get persistence there, the problem is not one server, it’s credential access, snapshot abuse, and lateral movement at scale.

What to do next:

  • Treat “virtualization and backup control planes” as Tier-0: fastest patch SLAs, strict admin access, and dedicated monitoring.
  • Hunt for unusual admin actions, unexpected network interfaces/routes, and suspicious outbound patterns from management systems.
  • If patch + verification capacity is thin, pair vulnerability management with targeted hunting.

Salt Typhoon: FBI says the telecom espionage threat is still ongoing

What happened: U.S. officials continue signaling that Salt Typhoon activity remains live. Reporting from CyberScoop quotes an FBI cyber leader describing the threat as “still very much ongoing,” reinforcing that the telecom compromise problem is not a closed 2024 chapter, it’s an enduring exposure with long-tail risk to public and private sectors.

Why it matters: Telecom-layer access can enable surveillance, metadata exploitation, and downstream targeting, classic national security stakes with broad second-order effects.

What to do next:

  • Reduce “quiet persistence” with continuous validation: harden and monitor edge infrastructure, enforce least privilege, and aggressively baseline what “normal” management traffic looks like.
  • Make sure DDoS, outages, or “routine” service events don’t become cover for stealthier intrusion steps, tie network events into incident response workflows.
  • Many organizations benefit from an IR retainer or on-call escalation path here; it’s less about buying tools and more about being able to prove eradication when adversaries optimize for staying power.

The CISA ChatGPT Data Leak and the “Shadow AI” Challenge

Recent reports have confirmed that the Acting Director of the Cybersecurity and Infrastructure Security Agency (CISA), Madhu Gottumukkala, uploaded several sensitive “For Official Use Only” (FOUO) documents to a public version of ChatGPT. While the documents were not classified, they contained sensitive contracting information not intended for public release. Although the Director had requested a temporary exception to use the tool, the incident triggered automated security alerts because the data was uploaded to a public platform rather than a protected, agency-approved environment.

This incident highlights a critical “Shadow AI” risk: the tendency for even the most security-conscious professionals to bypass established guardrails for the sake of convenience or productivity.

Bridging the Gap Between Policy and Practice
For many organizations, the disconnect between executive-level goals and day-to-day security compliance is a major vulnerability. We often see leadership teams inadvertently normalize the use of public AI tools without applying the same rigor used for other enterprise systems. Engaging Virtual CISO (vCISO) services can help bridge this gap by establishing governance frameworks that are both practical and inclusive. A vCISO ensures that security policies are not just a set of rules on a shelf, but are integrated into the workflow of every department, including the executive suite.

Technical Guardrails and Visibility
The CISA leak was detected because automated sensors were in place to flag the movement of sensitive data. This underscores the necessity of Security Configuration Audits, particularly concerning Data Loss Prevention (DLP) settings. Many organizations have the right tools but haven’t tuned them to recognize or block the “copy-paste” or “file upload” behaviors associated with public AI interfaces. Regularly auditing these configurations ensures your technical defenses stay ahead of evolving user habits.

Proactive Risk Identification
Understanding where your sensitive data lives and how it moves is the foundation of a strong defense. We recommend conducting a Best Practice Strategic Security Assessment or a targeted Risk Assessment to identify potential exposure points. These assessments look beyond traditional malware to examine how emerging technologies like Generative AI might be creating new, unmonitored pathways for data egress. By identifying these “exception pathways” early, you can provide safer, governed alternatives for your team.

Cultivating a Security-First Culture
Ultimately, security is a human challenge. This incident serves as a perfect case study for your next Security Awareness Training session. It demonstrates that the risk is not just about “bad actors” but about well-intentioned employees making mistakes with new tools. Training should focus on the specific risks of public LLMs, such as how OpenAI may retain and use uploaded data for model training, effectively making your private company data part of the public domain.

Other AI News We’re Tracking

  • Malicious AI “Skills”: We are monitoring reports regarding “OpenClaw,” an open-source AI agent system. Recent warnings highlight security risks where malicious “skills” or third-party plugins could be used to exfiltrate data from the environments where these agents are deployed. This represents a shift in supply chain attacks, moving from traditional software libraries to the emerging ecosystem of AI plugins.
  • Deepfake Financial Fraud: A recent report from Arup details a staggering $25 million loss due to a deepfake video call where an employee was convinced by “digital clones” of their CFO and colleagues to authorize multiple transfers. This highlights the need for multi-factor authorization processes that go beyond visual or vocal confirmation.
