A sophisticated “browser locker” campaign is spreading via #Facebook and pushing a #tech-support scam.


'''Browser lockers are a type of redirection attack where web surfers will click on a site, only to be sent to a page warning them that their computer is infected with “a virus” or malware. The page then typically urges targets to call a number on the screen for “tech-support help.” If they fall for it, they’re connected to a call center where they’re asked to pay a fee to “clean” their machines.

In a recent, widespread campaign, cyberattackers are using Facebook to distribute malicious links that ultimately redirect to a browser locker page, according to researchers. The links may be propagated through Facebook games, researchers at Malwarebytes noted in a post outlining its findings on Wednesday.'''
