SecureMac warns of new OS X Trojan Horse called AppleScript

SecureMac is reporting a new Trojan horse that threatens the Mac OS X 10.4 and 10.5 installation. AppleScript.THT, a new variant of the infamous Trojan Horse virus, is originating from a hacked website through iChat and Limewire.
The Trojan horse allows a malicious user to access a system remotely and transmit system and user passwords. It can also avoid detection through opening a port in a system’s firewall, as well as turning off system logging. AppleScript.THT can also log keystrokes, take pictures with Apple iSight camera, take screenshots and turn on file sharing.
SecureMac is also reporting that the Trojan horse is being distributed in two ways. As a compiled AppleScript known as ASthtv05, or as an application bundle called AStht_v06. When a user downloads and runs the script, the Trojan horse will then attack the system, and even moves itself into the /Library/Caches/ folder.
To protect your Mac OS X from getting infected by the virus, SecureMac is suggesting you run its MacScan 2.5.2 software.
