Researchers from INRIA, MSR, and IMDEA discovered the FREAK vulnerability in TLS/SSL implementations, including OpenSSL and Apple clients, which exploits weak export-grade 512-bit RSA encryption to enable man-in-the-middle attacks. The flaw stems from legacy U.S. export restrictions on cryptography that were never removed from implementations despite the policy ending decades ago. The discovery demonstrates the value of formal verification methods and systematic testing in identifying security weaknesses in complex cryptographic protocols.
Researchers have discovered a novel method to forge RSA signatures using classical computing without factoring the key, reducing security to unacceptable levels. The attack is practical against 1024-bit keys and significantly reduces computational requirements compared to traditional factoring approaches, though widely used implementations remain safe.
Researchers have discovered a novel classical computing attack on RSA that enables signature forgery without factoring, reducing computational requirements by orders of magnitude. The attack is now practical for 1024-bit keys and significantly weakens 2048-bit and 4096-bit RSA security, though widely used implementations remain safe for now.
DTec offers a software-based quantum encryption tool claiming to break RSA-2048 and protect personal data and infrastructure. The service provides post-quantum encryption and threat detection across multiple subscription tiers, starting with a free security assessment.
Researchers have discovered a novel classical computing attack on RSA that enables signature forgery without factoring keys, reducing computational requirements by orders of magnitude. While immediately impractical against widely-deployed implementations, the method brings 1024-bit RSA attacks into feasibility and degrades security of larger keys below acceptable thresholds.
Researchers implemented a 2007 algorithm that forges 1024-bit RSA signatures using a raw signing oracle in ~1,380 core-years, faster than factoring but requiring oracle access that most real-world RSA deployments don't expose. The attack doesn't pose immediate operational threats to properly padded RSA signatures, though it suggests RSA security estimates may need revision and supports transitioning to post-quantum cryptography.
A fictional retrospective set in 2036 describes the discovery that RSA-2048 had been factored, revealed through a series of mysterious cryptocurrency thefts and subsequent cryptographic failures that led an ISP network administrator to deduce a breakthrough in solving hard mathematical problems, ultimately confirmed when the factors were posted anonymously.
RSA-896 is a RSA cryptographic challenge number that was factored on September 19, 2026 using Claude. The factorization yields two large prime numbers p and q whose product equals the original RSA-896 number.
