Firesheep: Baaaaad News for the Unwary

Summary: Firesheep, a Firefox add-on released at the Toorcon hacker conference in San Diego, lets users on the same wired or wireless network capture session cookies from sites like Facebook and Twitter, which send post-login data in unencrypted plain text. Krebs tested it on two wireless routers with and without WEP/WPA and found it only captured his own logins until combined with a tool like Ettercap, which routes other users' traffic through the attacker's machine.

Key Takeaway: The weakness is not new - session and cookie hijacking has been discussed since at least 2003 - but Firesheep turns it into a point-and-click attack, and the only effective fix Butler names is full end-to-end HTTPS encryption, which popular sites had not adopted.
