"Unprecedented Attack: Cryptographic Keys Safeguarding SSH Connections Stolen"
Researchers have discovered that a significant number of cryptographic keys used to protect SSH connections are vulnerable to compromise due to computational errors during connection establishment. The vulnerability affects RSA keys used in approximately one-third of SSH signatures, potentially exposing the private key of the host. While most SSH software has countermeasures in place, the finding is surprising as previous research believed such attacks were limited to TLS protocol. The researchers suggest implementing additional protection in other protocols and emphasize the importance of defending against these failures.
