Anthropic says its AI Claude traced the seeds the NSA supplied for several NIST-standardized ECDSA curves to the C pseudorandom generator lrand48, seeded with a Unix timestamp between May 1997 and April 1998; Anthropic argues the pattern makes deliberate backdoors less likely and will donate the $36,864 bounty to the Internet Security Research Group.
Two prominent Ethereum researchers, including Justin Drake, warned that advances in AI-assisted mathematics could — in a worst-case scenario within months — enable attacks that recover private keys from public keys and break the ECDSA signatures used by many crypto wallets. Drake urged the community to prepare a "bunker mode" and move funds to addresses that have never signed; Vitalik Buterin agreed on the risk but cautioned against rushed migrations and advocated relying more on hash-based designs, noting no practical breaks have been reported so far.
