As predicted by the SecureMac team, the new version of BlackHole RAT 2 was officially released on a hacker message board this weekend, with some slight differences from the earlier version analyzed by SecureMac. The trojan horse, once installed, disguises itself as a Java Updater.

The new version has a more complicated installation process that requires physical access to the computer, so SecureMac continues to rate this as a low threat.

Read more details about BlackHole RAT 2.0

Trojan Horse Alert: Intego recently alerted users to the presence of a new variant of the HellRaiser Trojan Horse, which they identify as OSX/HellRTS.D. SecureMac has analyzed this new variant and it is detected in the latest MacScan spyware definitions update (Spyware Definitions Version 2010006) as HellRaiser Trojan Horse 4.2. MacScan has detected previous variants of this trojan horse since 2005.

HellRaiser is a trojan horse that allows complete control of a computer by a remote attacker, giving the attacker the ability to transfer files to and from the infected computer, pop up chat messages on the infected system, display pictures, speak messages, and even remotely restart or shut down the infected machine.

The attacker can search through the files on the infected computer, choosing exactly what they want to steal, view the contents of the clipboard, or even watch the user's actions on the infected computer.

In order to become infected, a user must run the server component of the trojan horse, which can be disguised as an innocent file. The attacker then uses the client component of the trojan horse to take control of the infected system.

This trojan contains the file extension of .mp3 although it is not, the icon itself is hardcoded into the trojan and not picked up based on file creator associations. The file itself is a Carbon (CFM) application with the file type of APPL. iTunes should not be able to execute a trojan or virus, and this file would only be able to run if double clicked on to execute it.
