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.
