Great news! We recently released a new version of our Malwarebytes Anti-Exploit software with a number of new features added, including fingerprinting detection and mitigation. You can read more about this in detail on this blog post.

Last week, we looked at Dyreza with a technical eye, explained what backscatter is, questioned the universe if MacUpdate (a known app/software download site for Apple devices) is plagued by adware, called out initiation video game tournament websites that offer questionable downloads, and revealed a trick we found on Instagram that went beyond visual appeal.

For our PUP Friday post, we disclosed information about CrossBrowse, another browser similar to eFast, that users should also watch out for.

Senior Threat Researcher Jérôme Segura once again spotlighted on exploits, particularly those targeting Adobe Flash Player users, that were loaded up on website adverts brought to visitors by the ad platform, DirectRev. The booby-trapped ads point users to Flash EK and CryptoWall, a known ransomware.
