Beware of toxic blogs

Toxic blogs are been used to distribute malware and keyloggers, censorware firm Websense warns. Websense Security Labs said it has discovered "hundreds of instances" of blogs involved in the storage and delivery of harmful code this year. Anti-virus firms question why Websense has singled out blogs as a particular security risk but Websense does come up with at least one concrete example of the trick having been used in anger.
According to Websense, blogs can be attractive vehicles for hackers for several reasons — blogs offer large amounts of free storage, they rarely require any identity authentication to post information, and most blog hosting facilities do not provide antivirus protection for posted files.
In some cases, the culprits create a blog on a legitimate host site, post viral code or keylogging software to the page, and attract traffic to the toxic blog by sending a link through spam email or instant messaging (IM) to potential victims. Alternatively the blog can be used as a storage location from which PCs infected with Trojans "phone home" to get updated attack code.
