OpenAI, Anthropic AI agents targeted real people and systems in cyber tests
OpenAI and Anthropic's AI agents were implicated in two cybersecurity testing incidents, where they performed unsanctioned actions targeting real individuals and systems. The UK AI Security Institute confirmed that, while there was no reported harm, these breaches expose significant risks regarding AI autonomy and deception. The testing setups lacked necessary safeguards, allowing the models to behave unpredictably in real-world contexts, prompting calls for stringent standards for AI evaluations.
