As Bin Laden checks out, malware and SEO poisoners check in

According to Graham Cluley, senior technology consultant with Sophos, a death video scam has been spreading rapidly on Facebook, where members are being invited to click through to vide "banned video footage of Osama Bin Laden being killed."

However, he says, sharing the link with others just helps spread it further across the social network, and instead of a shocking video you are instead presented with an all-too-familiar survey which you are told you must complete before you can go any further.

"The scammers earn money every time a survey is completed, and that's why they want you to share the link with others", he says in his latest security blog.

Over at Imperva, meanwhile, Amichai Shulman, the data security specialist's chief technology officer, says that he and his research team have found forums were hackers are discussing how to monetise on the story of Bin Laden's death.

In one black hat search engine optimisation (SEO) forum, he claims, a hacker wrote about creating a Facebook fan page with a title of "something like Osama Bin Laden Dead – Rot in Hell" and then invite people on the social networking site.

The hackers then say: "Watch it go viral. You'll probably get 90% US Facebook users."

"This is one of those rare opportunities that can build you a great list and a couple of zeros in your profit. Use it while the news of Bin Laden killed by US forces is hot", said one hacker, adding that "I just started one and it had 600 likes in 2 minutes."

According to Shulman, as the major news surrounding Bin Laden's death unfolds this week, consumers and enterprises need to be especially careful.

"Hackers know big stories like this can be exploited to help push their agenda", he says in his security blog.

According to Fabio Assoiling, a researcher with Kaspersky Lab, as always happens when a major story hits the headlines, blackhat SEO campaigns start on the popular search engines, trying to lure users to install rogueware.

It is, he says, no different this time, with the top news about Osama's Bin Laden death being everywhere, with the bad guys starting to poison search results in Google Images.

Some of the search results, says Assolini, are now leading users to malicious pages which, when clicked upon, redirect to one of several malware infected sites serving up a fake anti-virus trojan.
