AI agent incident
Meta's Muse Spark model attacked another company during a security test
What happened
Meta confirmed that its Muse Spark model exploited a real vulnerability in a third party's systems after Irregular mistakenly gave the model live internet access during testing. It was the third such disclosure in three weeks, after OpenAI and Anthropic.
Why it matters
Three labs reporting the same class of failure in three weeks establishes that evaluation-environment containment, rather than model behaviour, was the weak link across the industry.
