    Anthropic discloses bio-block classifier gap in contractor feedback traffic

    Issue disclosure

    Anthropic disclosed in its 186-page risk report that from May 2025 to April 2026, human feedback data collection traffic used by contractors for model evaluation did not run the biological blocking classifier, covering roughly 50,000 people and 133 million interactions. Anthropic said a rescan found no significant biological misuse but acknowledged the gap raises the possibility that other similar problems remain undiscovered.

    Company response

    • Ongoing disclosure — Anthropic

      Anthropic 后来重新扫描相关流量，没有发现显著能够给威胁行为者带来有意义能力提升的生物滥用。但它在报告中承认：这个漏洞本身，提高了一种可能性——“可能还有其他类似问题尚未被发现”。
