Juliano and Thai present their most recent attack against crypto system. CRIME: Information leakage attack against SSL/TLS. The root cause of the problem is information leakage that occurs when data is compressed prior to encryption. In practice, the attack works best against session cookies. The only browser to properly support TLS compression is Chrome and Firefox. Unlike BEAST, CRIME seems much easier to exploit; we will see a tool soon, maybe as a fork of sslstrip in the current version.”]
