Detecting Compromised SSL Certificates Using Nessus

When Thieves Target SSL Certificates

SSL is one of the most commonly used protocols to provide encryption for a variety of different applications. As such, it has come under great scrutiny over the years. While SSL misconfiguration is commonplace, one of the more recent attacks against SSL is to steal the Certificate Authority (CA) certificate. (In a paper released in July 2012, NIST warned that this type of attack would increase). Access to this certificate allows the attacker to issue valid certificates, and in the case of a code-signing certificate, use it to sign malware. Malware executing with this level of trust increases the chances of successfully being installed on the system. Other CA certificates are used to generate website certificates used by attackers to impersonate secure access to a given website.
