Bloggers were warned this week to raise their guard against posting potentially malicious referrer links into their Web logs.

It's potentially easy to hijack blogs through mendacious JavaScript code, a posting on one Web log (kasia in a nutshell) notes.

So the message is to double check referrers to make sure they link to a valid site, with links back to the blogger's site (if you will).

The risk is, of course, a generic one and certainly not specific to blogs. There's no strong evidence that blogs are being targeted as such, but the increasing popularity of Web logs and the (very) common practice of including multiple referrer links in blogs makes bloggers amongst the communities most at risk from the trick. ®
