Claude reportedly traces NIST elliptic-curve seeds to a 1990s random-number generator
A post relaying Anthropic's announcement says Claude linked the seeds to lrand48 initialized with 1997–98 system-clock timestamps.
TLDR
Posts relaying Anthropic's announcement say Claude took under 30 minutes to trace seeds for five NIST elliptic curves to lrand48, initialized with 1997–98 timestamps. One post says Valsorda independently reproduced the finding; another says Anthropic considers an NSA backdoor less likely. The curves are used in HTTPS, while Bitcoin and Ethereum's secp256k1 curve is unaffected, according to one post.
