In the past few weeks, a lot of Facebook users have received the following (or similar) messages posted by their friends
Hi Friends see Face-book images rotate 360* see here >> http://SHADYCLOUDS.TK/
Really cool Facebook revolving images. MUST SEE http://rotatingimage2.tk/.
Following are observations and analysis of the same.
So, today morning I received an email saying I recieved an orkut scrap from a friend with contents “Bom Sabado”.
Within a minute, I received same scrap from another friend. Now getting the feel that this must be some sort of worm, I decided to open Orkut with firebug logging enabled to see what’s going on.
It turns out that its a typical case of Cross-Site Scripting (XSS), the attacked is able to include and execute its own script from hxxp://tptools.org/worm.js and the contents of scrap are able to by-pass orkut sanitization.
