何が起きたか: Factoring RSA-260

Cognition's AI agent Devin factored RSA-260, a 260-digit number, using GPU-optimized lattice sieving at roughly 10x lower cost than previous records.

なぜ重要か: Factoring RSA-260

Security teams should monitor this if they manage RSA-1024 systems, which now face estimated $30M factoring costs within reach of well-resourced organizations.

注意点: Factoring RSA-260

RSA-2048 remains roughly a billion times harder than RSA-1024 and appears unaffected. The factorization used spare cluster compute and took about $400k in GPU resources.
