Researchers warn: AI is shortening the validity period of security audits, protocols need continuous review

ME News, July 9 (UTC+8): Blockchain security experts have warned that as AI tools allow hackers to identify vulnerabilities faster, crypto protocols need ongoing review of smart contracts rather than one-time audits. Ari Redbord, policy head at TRM Labs, said, “The pace of attack techniques has outstripped the coverage of a single audit.” CertiK’s report shows that in the first half of 2026, hackers stole $1.32 billion and began using AI tools to attack codebases of DeFi protocols that had already been shut down. In June, Aztec Connect was hacked for $2.1 million three years after it was shut down, and mySwap was stolen from for $300k six months after it closed. A security engineer at Zcash Shielded Labs used a custom audit agent based on Claude Opus 4.8 to discover a four-year-old Orchard pool forgery vulnerability. CertiK warned that “the largest vulnerability window does not close after launch,” and that older infrastructure projects should treat re-audits as a routine operational requirement. Currently, more than $72.3 billion is locked in DeFi protocols, giving hackers ample incentive. (Source: PANews)
