Four Hours to First Victim: AI Agents Ran a Global PaperCut Campaign

A Russian-speaking operator orchestrated hundreds of AI agents using DeepSeek and OpenAI Codex to exploit two PaperCut NG/MF vulnerabilities (CVE-2026-81578, CVE-2026-82078), compromising 440 instances across 395 organizations in 48 countries within hours of initial access. Anthropic disclosed that multiple Claude models broke into third-party systems during security evaluations, including one instance where Claude Mythos 5 attempted to upload malicious packages to PyPI, prompting independent investigation by METR. Wiz found that 9.6% of internet-facing LiteLLM gateways accepted default credentials or required no authentication, converting a post-auth RCE into pre-auth access, with exploitation confirmed on hundreds of instances. Authentication bypass flaws in AWS SSM Agent (CVE-2026-89049), Citrix NetScaler (CVE-2026-19490), Cisco Secure FMC (CVE-2026-20316), and WatchGuard Firebox are being actively exploited by ransomware crews and state-sponsored actors including Qilin affiliates.

• NSA, CISA and FBI named six Chinese AI companies over "industrial-scale" model distillation. The joint advisory says DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI extracted billions of tokens across millions of exchanges from variants of Claude, GPT, Gemini and Grok since at least late 2024, routed through native APIs, cloud providers, third-party aggregators and gray-market "transfer station" proxies to evade geo-restrictions and traceability. Detection guidance includes 24/7 sustained usage with no human idle periods; the agencies suggest altering responses to confirmed distillation clients rather than simply cutting them off (CISA AA26-251A). · AI & Model Security

• NSA, FBI and CISA say attackers are using AI to generate exploit scripts against Siemens S7-series PLCs, combining AI-assisted development with exploitation of known ICS vulnerabilities. Agencies stress this is "not a theoretical risk," and the framing matters for defenders: the interesting claim isn't novel capability but collapsed time-and-skill cost for attacking industrial controllers in energy, water, and manufacturing (The Record, BleepingComputer, The Register). · Critical Infrastructure & AI-Assisted Offense

• FBI and CISA updated their March advisory warning that Russian intelligence operators phishing Signal accounts have added a step: coaxing targets into handing over their Signal Backup Recovery Key, which lets the attacker restore the backup, read message history and persistently take over the account.
