XSS: Cross Site Scripting attack

| Sunday, December 18, 2011
XSS (Cross Site Scripting), now and then

In Nov., users of Facebook were "offered an opportunity for something (a shocking must-see video? a free iphone?)" if they could copy and paste a line into their address bar. A number of them did, they were then bombarded with explicit and violent content. For 24 hours, the content spread throughout the site and forced Facebook shut down malicious pages, and roll back any infected user accounts.

Facebook is a fertile ground for XSS infestation. It is only a surprise how blatant and "old timer" the manner of the attack (Yes, free iPhone!). Only in May, Facebook rolled out a "Self-XSS protection" security feature to protect users from such spam and scam, on the wake of three consecutive XSS attacks.

The first was passed as stories posted on users' wall, with a bit of iframe code embeded.
