Anthropic's Opus 4.8 Reportedly Discovers Critical Zcash Privacy Vulnerability, Triggers Hard Fork

An AI model appears to have found a critical bug in Zcash's privacy pool implementation that human auditors missed — and it's now reportedly turning its attention to Monero. AI-as-security-researcher is no longer theoretical.

Anthropic's Opus 4.8 model has reportedly uncovered a critical vulnerability in Zcash's (ZEC) privacy pool implementation, a discovery significant enough to trigger a hard fork of the protocol. The finding was flagged by several accounts on X, with @0xDawny noting that the "AI bug hunter" is now reportedly being directed at Monero's codebase as well. @MohdRas85952829 described the bug find as "wild," reflecting a broader sense of surprise in the crypto security community.
