DeepMind: AI agents factor legacy 1024-bit RSA keys in bulk within weeks
JMateosGarcia · x · 2026-11-07
Google DeepMind's science team, working with leading cryptanalysis experts, showed AI agents could make two significant cryptographic advances in just weeks: bypassing older digital signature protections and factoring legacy 1024-bit RSA keys in bulk.
- Modern schemes like RSA 2048 are not affected
- The takeaway: don't assume the mathematical "hardness" of legacy cryptographic schemes holds forever
- Also a demonstration of how AI can help defenders raise security standards ahead of future threats
Team lead Pushmeet Kohli published a longer essay, "Advancing the frontier of cryptanalysis," with full details.
