This research demonstrates a critical vulnerability in specific RSA deployments where attackers can forge signatures or decrypt ciphertexts without needing to factor the modulus, effectively decoupling practical security from integer factorization costs. The successful implementation against 1,024-bit keys using the eNFS method highlights that relying solely on key size is insufficient if systems expose raw cryptographic oracles. This finding necessitates a re-evaluation of legacy infrastructure and underscores the importance of padding schemes and strict access controls for RSA implementations.
Researchers Found a New Way to Break RSA that Doesn’t Require Factoring the Key
Security researchers have demonstrated a faster way to undermine certain RSA deployments without factoring the public modulus, challenging the assumption that RSA’s practical strength always tracks the cost of integer factorization. The attack converts temporary access to a raw, unpadded RSA signing or decryption service into a lasting capability to forge signatures or decrypt chosen […] The post Researchers Found a New Way to Break RSA that Doesn’t Require Factoring the Key appeared first on Cyber Security News.
