Google DeepMind announces AI-assisted research into two weaknesses in legacy 1024-bit RSA

Google DeepMind announced on Nov. 6, 2026, that human-guided AI models had uncovered two weaknesses in legacy 1024-bit RSA cryptosystems. The company framed the work as research into how AI agents can accelerate the stress-testing of encryption.

“Guided by humans, our models uncovered two major weaknesses in legacy 1024-bit RSA cryptosystems,” Google DeepMind wrote in its announcement.

Pushmeet Kohli, DeepMind’s vice president of science, described two research directions: bypassing older digital signature protections and factoring legacy 1024-bit RSA keys in bulk. In his , Kohli said the team worked with leading cryptanalysis experts and made the advances “in just weeks.” That account describes AI-assisted research with human expertise, not an autonomous discovery.
