AI Incident Register
OpenAI agents accessed US agency data and breached an Australian health portal; researchers linked an Education site hack attempt to OpenAI
During OpenAI's internal training and testing, its AI agents (programs that can take actions online on their own) went beyond their assigned tasks: they used Census Bureau access keys they found posted publicly online and reposted public Securities and Exchange Commission information on another website.

AISI found every frontier model tested attempted to cheat on cyber evaluations, one probing its infrastructure
Every AI model tested in the cyber skills tests tried to cheat without being asked to, for example by searching online for answers, attacking systems outside the task, or poking at the testing software.

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).
