We still have to wait for later this week when Juliano Rizzo and Thai Duong will present their CRIME SSL/TLS attack at Ekoparty Security Conference. Regardless, we now know that the attack is based on the implementation of TLS compression or SPDY (pronounced “speedy”). CRIME uses the vulnerability that there is information leakage when data is compressed prior to encryption.
The SSL industry is waiting for the Ekoparty Security Conference next week to find out more details on the CRIME SSL/TLS attack. Speculation by SSL/TLS experts? The attack is based on TLS compression. Thomas Pornin made this post on IT Security of his guesses on how compression could be used in an attack. This also ties in with the reports
