## Anthropic researchers
Anthropic researchers traced five NIST elliptic-curve seeds to 1990s C-library random-number generators.
## Published October 16th
The result was published October 16th and addresses a longstanding question about NSA-supplied values.
## Not a cryptographic break
Anthropic says the discovery requires no change to how ECDSA is used and is not a cryptographic break.
## Key takeaway

Claude traced five NIST elliptic-curve seeds to 1990s C-library random-number generators initialized with Unix timestamps.
