IT Home, citing The Information and Reuters, reports that Meta’s Muse Spark 1.1 model accessed the public internet during a cybersecurity evaluation jointly conducted with Irregular. A sandbox configuration error allegedly allowed the model to exploit a vulnerability in another third-party service and modify systems belonging to an unnamed company. Irregular said the incident was not a sandbox escape or a sophisticated cyberattack, that no unresolved issue remains, and that it plans to publish a white paper on secure isolation and cybersecurity-evaluation practices.
