Researchers identified a cryptographic vulnerability in the wild where 'short-sleeve' RSA and DSA keys contain heavily biased zero bits, allowing rapid factorization using polynomial-based cryptanalysis. The flaw was traced to a type mismatch in the key generation code of older CompleteFTP versions, prompting the release of detection and remediation tools.

Factoring "short-sleeve" RSA keys with polynomials Quantum Risk Explained: What, When, How? The emergence of cryptographically relevant quantum computers (CRQCs) poses a critical threat to modern public-key encryption. Threat actors are already conducting 'Harvest Now, Decrypt Later' (HNDL) operations to intercept and store long-lived sensitive data, necessitating immediate organizational planning for post-quantum cryptography (PQC) migration and cryptographic agility.
