Claude Factors RSA-896 Challenge Number, Researcher Claims
Singularitarian · x · 2026-09-20
Cryptographer Stephen A. Weis says he factored the RSA-896 challenge number with Claude on September 19, 2026, and published the full composite N along with the two prime factors p and q.
- The factors are roughly 270-digit primes, given in full decimal form.
- If verified, it would mean an AI model can assist in breaking the 896-bit RSA challenge number, adding empirical pressure on the classic hardness assumption behind integer factorization.
- The post gives no method, runtime, compute budget, or third-party verification, so the claim should be treated with caution.
