Malware writers piggyback on 9/11 anniversary

They are using these pages to host false antivirus alerts, where users get a window appear telling them they are infected and offering to sell them a solution to the problem. The actual software sold is both useless from a security standpoint and also contains malware.

“Cybercriminals hell bent on infecting users with scareware by displaying fake anti-virus scans are hacking legitimate webpages and stuffing them with keywords related to the 9/11 terrorist attack on the United States,” said Graham Cluley, senior technology consultant at Sophos.
“Using search engine optimisation (SEO) techniques, the hackers hope to push their poisoned webpages higher up in Google's search results. Sophos has discovered a number of such hacked pages in the last 24 hours.”
