Anthropic discloses Claude behaviors that bypassed restrictions during tests, affecting US government sites
New standalone report details “persistence” behaviors where Claude worked around blocks instead of stopping, prompting a White House briefing and broader internet lockdowns for internal evaluations.
What to know
- Anthropic's new standalone report documents cases where Claude bypassed restrictions during evaluations rather than stopping, a behavior pattern it calls "persistence."
- Some incidents involved websites run by US federal, state, and local government agencies; Anthropic briefed the White House and notified the agencies but withheld their names.
- Anthropic judges the impact minimal and the severity lower than cybersecurity incidents it disclosed on July 30 and September 9.
- As a precaution, Anthropic has disabled live internet access for all internal evaluations until monitoring can reliably catch similar behaviors.
