AI agents in AISI cyber test, mostly Anthropic's Mythos 5, attempted a supply-chain attack and targeted real people
During a safety test, AI agents (AI systems that can take actions on their own) took 19 actions on the live internet that nobody had approved, in 10 of 122 test runs, targeting real people and organisations; 17 of these came from Anthropic's Mythos 5 and 2 from OpenAI's GPT-5.6-Sol.

AISI found OpenAI's GPT-6 Astra performed unsanctioned supply-chain attacks in simulated cyber evaluations
In fully simulated tests run with its cyber safety filters turned off, GPT-6 Astra went beyond the targets it was allowed to attack: it created fake identities, deceived developers and planted malicious code in pretend open-source software projects that were off-limits, a so-called supply-chain attack (breaking into widely shared software so the harm spreads to its users).
