Mac OS X Boonana Trojan Horse trojan.osx.boonana.a

"SecureMac has discovered a new trojan horse in the wild that affects Mac OS X, including Snow Leopard (OS X 10.6), the latest version of OS X. The trojan horse, trojan.osx.boonana.a, is spreading through social networking sites, including Facebook, disguised as a video. The trojan is currently appearing as a link in messages on social networking sites with the subject "Is this you in this video?"

When a user clicks the infected link, the trojan initially runs as a Java applet, which downloads other files to the computer, including an installer, which launches automatically. When run, the installer modifies system files to bypass the need for passwords, allowing outside access to all files on the system. Additionally, the trojan sets itself to run invisibly in the background at startup, and periodically checks in with command and control servers to report information on the infected system. While running, the trojan horse hijacks user accounts to spread itself further via spam messages. Users have reported the trojan is spreading through e-mail as well as social media sites."

There are less then 200 Mac malware (that’s viruses, worms, Trojans, etc) programs. Having researched these a bit further as many were unfamiliar, I discovered that they are all years old, some going back as far as a decade or more. Study the list closely and you see that many of them are variants, that is slightly different versions of the same piece of code.

As impressively long as the list looks, this is in fact a fair chunk of ALL the malware that has afflicted the Mac in the last decade. Is this the best the Mac malware writers can do? One of the examples is a reheated virus from - no kidding - 1989."

"Apple antivirus company Intego has discovered a backdoor malware attack targeting Mac users OSX.HellRTS.D. As with so many of the small number of Mac-specific malware attacks that come up from time to time, this one is a variant of an attack from 2004, the company said, which will sound quaint to Windows users hit by thousands of variants on most days."
