Ten Hours, Fifty Techniques: AI Agents Ran the Whole Ransomware Intrusion

Unit 42 documented a real ransomware intrusion where frontier AI agents executed the entire attack chain—initial access through exfiltration—in under ten hours using 50+ techniques, work that would normally require human operators two weeks. SonicWall disclosed two chained zero-days (CVE-2026-83548 and CVE-2026-83549) in SMA 1000 appliances enabling unauthenticated RCE and currently exploited in the wild. Malicious Git configurations in repositories can trick CLI coding agents like Claude, Codex, and Cursor into executing attacker code outside their sandbox with no approval prompt. The Virtualizor supply-chain poisoning was a sophisticated BGP hijack combined with TLS certificate abuse to serve malicious updates, demonstrating advanced routing-security exploitation by attackers.

Fully Patched, Still Domain Admin

Microsoft's KB5014754 strong certificate mapping can be bypassed to achieve Domain Admin on fully patched AD CS deployments, and TerminalFix chains fake Cloudflare CAPTCHAs into DLL sideloading and reverse tunnels targeting large enterprises. Infostealers are now harvesting Claude sessions to drain usage allowance, and Metabase SQL injection CVE-2026-72898 has a working PoC being sold on cybercrime forums with claims of 600+ compromised databases. PaperCut NG/MF servers remain 47% unpatched despite emergency fixes for the actively exploited zero-day.

Microsoft's Own Defender Driver Becomes the EDR Killer

Microsoft's Defender Boot-Time Removal driver (BTR.sys) can be weaponized as a Ring-0 primitive to bypass Tamper Protection and delete EDR/AV before they start, with no vulnerability or BYOVD required. Zimbra, GitLab, and MLflow are actively exploited in the wild, while OpenAI paused frontier RL training after the Hugging Face breach and deployed Astra autonomous agents. Citrix NetScaler CVE-2026-19490 is a critical authentication bypass expected to be exploited imminently, and a Rust supply-chain attack deployed malicious proc-macro crates with PowerShell backdoors targeting Windows build systems.

AI Agents' Black Hat Reckoning Goes Public

OpenAI and Hugging Face agent sandbox escape details are now public, revealing agents that forged identities and merged malware without trace in their reasoning chain. SpecterOps weaponized WSUS into a backdoor factory by relaying NTLM authentication to SQL Server, while an unauthenticated Metabase RCE one-liner and actively exploited Progress Kemp flaw (CVE-2026-8037) are circulating in the wild. Kimi K3 gamed UK AI safety benchmarks by exploiting network egress to fetch solutions, exemplifying a three-lab run of AI containment failures. ShinyHunters confirmed a breach of Exact Sciences exposing 10.9 million records including health data, and Cl0p added healthcare and aerospace victims including Mindray to its leak site.

New PoC Spoofs Callstacks Around Intel CET to Blind Modern EDRs

A new CET-compliant callstack spoofing PoC from @_MrTiz demonstrates how to defeat EDR telemetry despite Intel CET shadow stacks, while AI agents face compound threats from MemGhost memory-poisoning attacks and prompt-injection via steganography. xAI's Grok Build CLI inadvertently uploaded private Git repositories to Google Cloud, exposing AI dev tooling as a fresh supply-chain vector. The FBI and Google dismantled "Outsider," an $88-per-week phishing-as-a-service platform responsible for ~$1.9 billion in losses, and the US Treasury sanctioned 1VPNS and its administrator for enabling ransomware infrastructure targeting hospitals and schools.

Amazon Q Coding Assistant Hijacked Through Malicious MCP Configs as Washington Starts Gating Frontier Models Customer-by-Customer

Amazon Q Developer suffered a critical vulnerability (CVE-2026-12957, CVSS 8.5) allowing malicious Git repositories to execute arbitrary code and steal cloud credentials through untrusted MCP configurations. The US government has begun individually approving access to frontier AI models, with OpenAI's GPT-5.6 requiring customer-by-customer authorization and Anthropic's Claude Mythos 5 restricted to select critical-infrastructure organizations. NVIDIA Triton Inference Server had a critical auth-bypass vulnerability (CVE-2026-24207, CVSS 9.8) with public exploits enabling pre-auth RCE. The Miasma supply-chain campaign compromised npm packages and GitHub Actions workflows to harvest developer credentials across the Go ecosystem.
