New Mac OS X Trojan Horse in the Wild

New Mac OS X Trojan Horse in the Wild

The Trojan allows malicious users to transmit system- and user- passwords, at the same time avoiding detection by opening ports in the firewall and turning-off system logging.

Multiple variants of a new Trojan horse have been discovered in Apple's Mac OS X; the Trojan runs under cover on the operating system giving a malicious user complete remote access to it, according to SecureMac, a Mac-focused security firm.

The Trojan named 'AppleScript.THT' on Mac OS X version 10.4 and version 10.5 is currently being distributed from a hacker Web site, where discussion has apparently taken place on distributing it through iChat and Limewire.

The Trojan allows malicious users to transmit system- and user- passwords, at the same time avoiding detection by opening ports in the firewall and turning-off system logging. In addition, it can log keystrokes, take pictures with the built-in Apple iSight camera, take screen-shots, and turn on file-sharing.

According to SecureMac, the Trojan is being distributed either as a compiled AppleScript called ASthtv05 (60KB in size) or as an application bundle called AStht_v06 (3.1MB in size). A PC can get infected if the user downloads and opens the Trojan Horse. Once the Trojan is running, it automatically moves into the /Library/Caches/ folder, and adds itself to System Login Items. The Trojan is said to exploit a recently-discovered vulnerability in the Apple Remote Desktop Agent (ARDA) that allows it run as root.

Another security firm called Intego has warned that any application could use this vulnerability to obtain root privileges without users ever needing to enter passwords.

This article sounds like an ad for someone selling security software. Remember that you're safe unless you download and run this program.
