Cyber criminals will jump at any chance and use any news to spread malware, and news doesn't get much bigger right now (sorry William and Kate) than the death of Osama bin Laden. It was obvious that we would see SEO poisoning leading to malware, image search poisoning, spam campaigns, and so on.

Twitter is a great source of information, and in the aftermath of the news of bin Laden's death, people started noticing that a Twitter account called @ReallyVirtual based in Abbottabad, Pakistan had tweeted about hearing helicopters and explosions in the area six hours before the news became public. Essentially he live tweeted during the attack.
As can be seen from the screenshot, Mr. Athar links to his blog, and I'm sure a lot of users who saw his tweets went there. Unfortunately for them, the site was compromised and was serving a poorly detected malware through the Blackhole Exploit Kit. Websense customers were proactively protected against this thanks to our real-time analytics in ACE. Below is a screenshot of what the site looks like:

To convince the user that something really is wrong with the system, the malware hides all files and folders in the hard drives and on the desktop:
But of course the scammers offer the user a quick solution to this problems with a purchase of the premium version of 'WindowsRecovery':
