The rogue post includes a link to a supposedly "Facebook extension". Clicking on the link and following the instructions will eventually install the virus on your computer. That's how the virus spreads. It's a pretty smart virus; it even tags friends in the post. Do yourself (and your computer) a favour and do not click on any link. If you see such a post, I recommend adding a comment to the post warning others (possibly with a link to this blog post); this may help your friend understand the error he made, and prevent future contamination.
The latest victim to be hit by this scam is Bhutan's first IT Park, Thimphu TechPark (no relation to this blog). Here is the post that was made by the virus on their behalf. The malicious link is the one inside the post that ends with .TK (a Turkish website). Although the claim is that if you install the software "You won't be disappointed", I promise you that you will.
|Beware: this is a hoax.
