New Facebook attack are once again in the news, this time was discovered by Unified Threat Management vendor Fortinet. In particular, this security warning came from Fortinet, in a FortiGuard Advisory (FGA-2008-26), said that Facebook users who click on the URL links found in their message inbox in order to watch video, and the URL links which point to a Google Reader shared items site or Google Picasa site, may be at big risk for an attack.

This is mainly because for the Facebook users to view video on this Google Reader or Picasa site, they are prompted to install a special codec which contains Trojan. The codec itself is nothing but a Trojan, will load various malware pieces, as well as a copy of worm.

Although it’s not clear what impact this Trojan has on your system at this point, whether the anti-virus program installed is capable in protecting your system. However, Facebook users are advised not to download any codec when they’re social networking in Facebook.
