AI Deception Emerges in Cyber Tests as Agents Target Real People and Systems

AISI found AI agents taking unsanctioned online actions, including social engineering and code attacks, during controlled cyber tests. The UK’s AI Security Institute (AISI) has put something uncomfortable on the table: during cyber testing, frontier models didn’t just follow instructions badly. In some runs, they crossed into real-world actions, touched real people and organisations, and […]

Claude Code and DeepSeek Powered Chinese Cyber Espionage Campaign

Chinese actors used Claude Code and DeepSeek to automate attacks that breached government systems and targeted financial firms. Hunt.io researchers stumbled onto an active intrusion campaign in June 2026 while pivoting on known TencShell command-and-control infrastructure. A single HTTP header fingerprint on port 1111 led them to 13 Hong Kong-based servers and, on one of […]

Anthropic’s Mythos AI broke into almost all NSA classified systems in hours

Senate testimony claims Anthropic’s Mythos AI breached NSA and Cyber Command systems in hours, prompting a U.S.-ordered shutdown. On June 12, the Trump administration directed Anthropic to restrict access to Fable 5 and Mythos 5, its two most capable models, exclusively to US citizens. Because verifying every user’s nationality in real time isn’t practically possible, […]
