New Mac Malware Uses Right-to-Left Override To Trick Users

by

By Michael Sweeting After a relatively long lag period without seeing any particular new and exciting Mac malware, last week we saw the surfacing of a new and interesting method of compromising the OSX system. Malware authors have taken a new approach by altering file extensions of malicious .app packages in order to trick users into thinking they are opening relatively harmless .pdf or .doc files. Changing file extensions in Mac OSX can be tricky due to a built in security feature of the OS that detects attempts to change the extension and automatically annexes the extension of its correct […]

Adware Purveyors Panning for Search Gold

by

We know most adware companies are shameless in their pursuit of revenue, but it’s been a while since we’ve seen anything as bizarre (or hilariously bold) as the sales pitch from a relative neophyte to the world of adware, which calls itself SnappyAds. On its homepage, SnappyAds posits the hypothetical glee of two business-suited online ad men counting the thousands of dollars they’ve allegedly earned from their allegedly lucrative venture. Behind the SnappyAds facade, however, is an adware client we (and a few other AV companies) call SearchPan. The installer for the adware client application is hosted on SnappyAds’ webserver, […]
