For the longest time, Apple users were relatively immune to the malware woes of their Windows counterparts due to the smaller market share held by OS X. But the days of security by obscurity may have come to an end. On Halloween, researchers discovered a trojan horse, masquerading as a video CODEC, that gives full remote control of the computer to remote hackers. At the moment, the OSX.RSPlug.A Trojan only downloads when OS X is detected by particular pornography sites, promising to enable users to view video. A user still must acknowledge and install the download; however, it was packaged well enough to fool the typical browser. Fortunately, this first generation trojan is both easy to detect and remove.
