New HTTPS Bicycle Attack Reveals Details About Passwords From Encrypted Traffic (softpedia.com)

campuscodi writes: Dutch security researcher Guido Vranken has published a paper [PDF] in which he details a new attack on TLS/SSL-encrypted traffic, one that can potentially allow attackers to extract some information from HTTPS data streams. Attackers could extract the length of a password from TLS packets, and then use this information to simplify brute-force attacks. The new HTTPS Bicycle Attack can also be used retroactively on HTTPS traffic logged several years ago. Hello NSA!
