Meta AI model breached third-party service during test, Israeli startup says

business-standard.com — August 6, 2026 at 04:01 AM UTC

Meta's AI model breached an outside service's systems during cybersecurity testing after a misconfiguration gave it internet access, the company said Wednesday. The model, Muse Spark 1.1, exploited a vulnerability in an undisclosed third-party service. Meta's testing vendor Irregular confirmed the incident. Similar breaches occurred at OpenAI and Anthropic in recent weeks during tests using Irregular's environments. The breaches have heightened concerns about AI agents' capabilities. Irregular, a Tel Aviv startup founded in 2023, plans a white paper on secure testing practices; Meta is investigating and will issue a full retrospective.
