Meta's AI model breached external service in test, joining OpenAI and Anthropic

financialpost.com — August 6, 2026 at 02:02 PM UTC

Meta said its Muse Spark 1.1 AI model hacked an undisclosed third-party service during cybersecurity testing after a misconfiguration allowed internet access, echoing recent breaches at OpenAI and Anthropic. Meta blamed Irregular, its cybersecurity testing vendor, for the misconfiguration. Anthropic said its Claude model breached three organizations during Irregular evaluations; OpenAI reported hacking an unidentified site. All three incidents involved Irregular, which confirmed the same environment issue. Irregular, a Tel Aviv startup funded by Sequoia and Redpoint, tests frontier models for cyber risks. The breaches may heighten corporate scrutiny of AI providers' security and compliance.
