🔒Cognition Team Cracks RSA-260 With GPU-Optimized GNFS
GPU-powered factorization drops RSA-260 barrier
TL;DR
The Cognition team used GPU-optimized GNFS to factor RSA-260, a 260-digit number, at a cost of $400,000. This breakthrough lowers the barrier to entry for cryptanalytic work and large-scale scientific computing.
The Cognition team cracked RSA-260, a 260-digit number, using a GPU-optimized version of the general number field sieve (GNFS). This marks a significant milestone in computational mathematics and cryptography, as it demonstrates the power of GPU clusters in tackling complex factorization problems. For developers and researchers, this means that the cost of performing such computations is dropping, making it more accessible for smaller teams and projects. The factorization cost about $400,000, with 643 GPU-days in polynomial selection, 3,813 GPU-days sieving, and 467 GPU-days linear system solving. The team used spare compute resources, highlighting the potential for more efficient use of existing infrastructure.

Why It Matters
If you're working on cryptanalytic projects or large-scale scientific computing, this breakthrough lowers the cost barrier. For example, factoring RSA-1024 would cost roughly $30 million, making it more accessible for smaller teams. However, RSA-2048 remains roughly a billion times harder, so the impact is limited to specific use cases.
