What happened
ISO/IEC has an Approved Work Item (AWI) TR 27259, 'Information technology — Artificial intelligence — Taxonomy of misuse patterns in AI applications' (Edition 1, © ISO 2026), currently under development with a draft prepared by a working group. This is a distinct new SC42 work item from the already-covered AWI TR 27258 ('Interactions in multi-agent AI systems'). The publication/registration date is not explicitly shown on the ISO page or in search results, so the in-window timing could not be definitively established; it appears alongside the recently-registered TR 27258 in the same SC42 work-item batch.
Why it matters
SC42 is the international AI standards body, and misuse-pattern taxonomy work feeds directly into how AI security incidents and attacker misuse of in-use AI systems are classified and reported. It complements TR 27258 (multi-agent interactions) and the AI-incident reporting data-element work referenced in NIST IR 8621. A structured taxonomy of in-use misuse patterns would help organisations and regulators align on detection and reporting semantics.
Action needed
Monitor ISO 27259 progress and, if participating in SC42, track the working draft for comment; map the resulting taxonomy to existing AI-risk frameworks (NIST AI RMF, MITRE ATLAS, OWASP).
