Anthropic traces cryptographic curve seeds to an old random-number generator

Anthropic said on October 16 that an internal Claude research model traced five NIST prime-curve seeds to their origins. The method recreates the seeds with a 1990s random-number generator initialized with timestamps. Anthropic published the code so other researchers can test the result.

Anthropic's findings do not show that the signature system is broken, and the company says no change is needed. Researchers still do not know the origins of some base points or one binary-curve seed. The method also does not recover every design choice.

GitHub adds license checks that can block enterprise merges

GitHub made its open-source license checks generally available on October 16. Enterprise Cloud customers with Code Security can set one policy for dependency licenses. When a ruleset is active, GitHub can block a pull request that adds a dependency outside that policy. A new API lets coding agents check a package before they add it.

GitHub says the checks compare each dependency with a company's policy. They do not give a legal opinion on every use of a package, and the configuration affects the result. Evaluate mode flags findings without blocking a merge, though a separate comment-resolution rule can still block it.

Waymo aims to carry Toronto riders in 2028 after manual mapping and supervised tests

Waymo said on October 16 that it aims to carry its first Toronto riders in 2028. Human drivers will first map the city's streets. Trained specialists will then sit behind the wheel during testing. Element Fleet Management will provide fleet services.

This is a company expansion plan, not a driverless service that has already launched. Manual mapping and supervised testing do not show that the system is ready for Toronto passengers.

IMF chief warns AI risks could outweigh benefits without safeguards

IMF chief Kristalina Georgieva said on October 16 that AI's risks could outweigh its opportunities without safeguards, Reuters reported. Speaking on a panel in Bangkok, she said AI was strengthening the economy. She warned of economic shocks if productivity gains fell short. The IMF agenda lists Anthropic co-founder Jack Clark as a panelist.

Georgieva warned about a possible shock, not one that has happened. She supported industry self-regulation with government and public involvement, but her remarks do not create binding standards.
