Anthropic's Claude solved in under 30 minutes the mystery of the origins of the curve parameter seeds in the NIST 2000 ECDSA standard provided by the NSA. The seeds came from the C language random number generator lrand48, initialized with Unix timestamps between May 1997 and April 1998; Claude spotted the pattern because lrand48 outputs only 31 bits, leaving some seed high bits systematically zero.
