Black hat 2010


Two researchers at the Black Hat conference in Las Vegas on Thursday exposed 24 ways hackers can hijack seemingly secure browser sessions.
Robert Hansen and Josh Sokol demonstrated methods attackers can use to take over users' accounts or assume control of a website without the need for any exploits, due to the way browsers implement "HTTPS." HTTPS, a combination of the Hypertext Transfer Protocol with the SSL/TLS Protocol, allows a website owner to encrypt a session using a digital certificate.
For any of the two dozen attacks to work, however, a criminal would have to have assumed control of a user's computer via a man-in-the-middle (MITM) exploit, by which an attacker intercepts communications between two systems.
But the researchers wanted to show that HTTPS protection alone won't stop bad things from happening.
