Two security researchers claim to have developed a new attack that can decrypt session cookies from HTTPS (Hypertext Transfer Protocol Secure) connections. From the security researchers who created and demonstrated the BEAST (Browser Exploit Against SSL/TLS) tool for breaking SSL/TLS encryption comes another attack that exploits a flaw in a feature in all versions of TLS.
The new attack has been given the name CRIME by the researchers. The CRIME attack is based on a weak spot in a special feature in TLS 1.0, but exactly which that feature is has not been revealed by the researchers. They will say that all versions of TLS/ SSL including TLS 1.2, on which the BEAST attack did not work are vulnerable.
