## Executive Summary

Active exploitation of critical infrastructure vulnerabilities has accelerated across multiple vendor platforms, with CISA adding four actively exploited flaws to its Known Exploited Vulnerabilities catalog in a single week. Citrix NetScaler ADC and Gateway appliances face two remote code execution zero-days (CVE-2026-88771, CVE-2026-88772) with CVSS scores up to 9.5, while Microsoft SharePoint (CVE-2026-65660, CVSS 8.8) and MikroTik RouterOS are also under active attack [CISA Says Attackers Are Exploiting Two Critical Citrix NetScaler Flaws Globally](https://thehackernews.com/2026/09/cisa-says-attackers-are-exploiting-two.html) [Citrix confirms two NetScaler RCE zero-days exploited in attacks](https://www.bleepingcomputer.com/news/security/citrix-admins-warned-to-shut-down-netscalers-over-2-exploited-zero-days/) [SharePoint RCE and MikroTik RouterOS Flaws Actively Exploited in the Wild](https://thehackernews.com/2026/09/sharepoint-rce-and-mikrotik-routeros.html). Oracle PeopleSoft environments are being targeted through a WAF bypass technique against CVE-2026-35273 by the ShinyHunters extortion group [ShinyHunters uses WAF bypass trick in Oracle PeopleSoft attacks](https://www.bleepingcomputer.com/news/security/shinyhunters-uses-waf-bypass-trick-in-oracle-peoplesoft-attacks/). These developments demand immediate patching prioritization and compensating control validation across exposed attack surfaces.

Agentic AI threats have moved from theoretical to operational, with the JadePuffer ransomware operator deploying autonomous AI agents to conduct reconnaissance, credential theft, and destructive actions against Azure tenants [JadePuffer agentic AI attacks target Azure, destroy cloud resources](https://www.bleepingcomputer.com/news/security/jadepuffer-agentic-ai-attacks-target-azure-destroy-cloud-resources/) [JadePuffer AI Actor Compromises Azure Tenant in Destructive Cloud Attack](https://www.darkreading.com/cloud-security/jadepuffer-ai-actor-azure-tenant-destructive-cloud-attack). Simultaneously, the Carbonato botnet is compromising exposed Docker daemons to deploy the Hermes AI agent framework under Telegram command-and-control [Carbonato Botnet Compromises Docker Hosts to Deploy Telegram-Controlled Hermes AI Agent](https://thehackernews.com/2026/09/carbonato-botnet-compromises-docker.html). Infostealer logs have exposed AI account credentials and sessions tied to more than 80,000 corporate domains, fueling an emerging LLMjacking market [80,000+ Organizations Had AI Logins Stolen: From Shadow AI to LLMjacking](https://www.bleepingcomputer.com/news/security/80-000-plus-organizations-had-ai-logins-stolen-from-shadow-ai-to-llmjacking/). Only 47% of CISOs report confidence in identifying every AI agent in their environment, indicating a systemic governance gap [Webinar: How to Govern AI Agents, Reduce Excessive Access, and Control Shadow AI](https://thehackernews.com/2026/09/webinar-how-to-govern-ai-agents-reduce.html).

Supply chain integrity failures persist in trusted distribution channels. A malicious Chrome extension masquerading as an ad blocker exfiltrated sensitive data from millions of users while bearing Google's store approval [Chrome Store Hosts 'Poper Blocker' Spyware Downloaded by Millions](https://www.darkreading.com/application-security/chrome-store-poper-blocker-spyware-downloaded-millions). The ShinyHunters investigation escalated following a Dutch police arrest, with remaining members retaliating through data theft from the FBI and extortion of the Cl0p ransomware group [Dutch Police Arrest ‘Reformed’ Hacker in Shiny Hunters Investigation](https://krebsonsecurity.com/2026/09/dutch-police-arrest-reformed-hacker-in-shiny-hunters-investigation/). These events underscore the volatility of threat actor dynamics and the cascading risk from law enforcement actions.

**Near-term (1-4 weeks)**
- Conduct AI agent inventory across all environments; enforce least-privilege principles for agent identities and API connections [Webinar: How to Govern AI Agents, Reduce Excessive Access, and Control Shadow AI](https://thehackernews.com/2026/09/webinar-how-to-govern-ai-agents-reduce.html)
- Rotate all AI platform credentials (OpenAI, Azure AI, Anthropic, etc.) exposed in infostealer logs; implement session monitoring for anomalous LLM usage [80,000+ Organizations Had AI Logins Stolen: From Shadow AI to LLMjacking](https://www.bleepingcomputer.com/news/security/80-000-plus-organizations-had-ai-logins-stolen-from-shadow-ai-to-llmjacking/)
- Audit Docker daemon exposure; disable unauthenticated TCP sockets; deploy runtime detection for unauthorized AI agent frameworks [Carbonato Botnet Compromises Docker Hosts to Deploy Telegram-Controlled Hermes AI Agent](https://thehackernews.com/2026/09/carbonato-botnet-compromises-docker.html)
- Implement browser extension allow-listing and enterprise mobility management controls to prevent unauthorized Chrome store installations [Chrome Store Hosts 'Poper Blocker' Spyware Downloaded by Millions](https://www.darkreading.com/application-security/chrome-store-poper-blocker-spyware-downloaded-millions)

**Strategic (30-90 days)**
- Establish AI governance framework covering agent lifecycle, identity management, and autonomous action logging; align with emerging standards for agentic AI security
- Develop threat actor retaliation playbooks incorporating law enforcement coordination triggers and cascading extortion scenarios
- Integrate KEV catalog monitoring into continuous vulnerability management with automated SLA tracking for critical infrastructure assets
- Expand third-party risk assessments to include AI agent supply chains and browser extension ecosystems
