According to a Symantec blog post, researchers have discovered attackers using fake Facebook accounts to post links to view free movies and sporting events in the comments of popular articles and posts on Facebook, Buzzfeed, ESPN, and the Huffington Posts.

The links lead users to tech support scam sites.

After the scammers post their comments, they return in five to ten minutes and edit their posts and add a malicious link. If the user clicks on the link, they are redirected to a site through AdCash, a site known to host malicious advertisements, to a site that mimics the tech support websites for a user's device.

The page that they are directed to contains false warnings that state the users computer is infected with malware. They are then compelled to contact the scammers and asked to provide sensitive information.
