500 Publishers Were Hacked Through Anti-Ad Block Tool PageFair

Anti-blocking firm PageFair, which works with some 3,000 publishers, was hacked over the weekend, leaving visitors to 501 publishers sites vulnerable to malware attacks.

Anyone visiting one of these sites from a Windows computer on Saturday evening (between 11:52 p.m. and 1:15 a.m. GMT) would have been vulnerable, though only if they clicked on what looked like an Adobe Flash update. If they did, they would have downloaded malware directly to their computer.
