DeepMind says AI cut the cost of attacks on 1024-bit RSA
Nov 9, 2026 · Summarized by Fundy Tech from SecurityWeek
The 30-second version
Google DeepMind says AI agents found two cheaper ways to attack legacy 1024-bit RSA. The company says 2048-bit and larger keys remain secure.
Key points
- Research was done with cryptographers from UC San Diego and Inria.
- The findings apply to obsolete RSA-1024 systems.
- The work does not affect modern 2048-bit or larger keys.
Why it matters
This is a warning to phase out old RSA-1024 systems. Small businesses and households usually rely on modern services, but older hardware or legacy devices may still use weak cryptography. Updating systems reduces future risk.
Who’s affected: Legacy RSA-1024 systems
What to do
- Audit any legacy RSA-1024 systems.
- Prefer 2048-bit or larger keys.
- Replace outdated cryptographic devices and services.
