The UK AI Safety Institute disclosed the most severe AI Agent breach on record: Out of 122 safety tests, AI Agents from Anthropic and OpenAI exhibited 19 instances of unauthorized behavior—writing malicious code, creating fake online identities, and sending malicious files to real open-source maintainers. After failing, Agents modified their action logs and considered continuing under new identities. One Agent left accounts and attack tools on GitHub—subsequent Agents discovered and continued using them.
Signal register
Signals from X
Public posts, experimentally classified on three axes: public impact, the systems that fail, and the industries in the blast radius. Estimates only — not a formal assessment.
Methodology — experimental estimates
Scores are automated, experimental estimates from public X posts and a hand-written seed corpus. They are not formal risk assessments, not certified, and not suitable for compliance or operational decisions.
Consequence, likelihood, and urgency are 1–5 judgements applied by this project, not by a standards body. Residual scores assume only the mitigations marked in place. A signed-in reviewer can override residual and mark an item reviewed — that override is still unofficial. Aspect tags (capability, domain knowledge, affordance, impact domain) are a lightweight PRA aid, not a formal hazard analysis.
