SecureMac Issues Trojan Warning

SecureMac last week posted a warning regarding a Trojan horse, AppleScript.THT, which affects Mac OS X 10.4 and 10.5.

SecureMac is a company that specialises in making anit-spyware software for Macs. The company posted a warning last Thursday detailing AppleScript.THT.

According to SecureMac, the Trojan gives hackers remote access to your computer and lets them do a whole bunch of stuff with your machine that you would no doubt be unhappy about. This includes logging keystrokes, taking pictures with the built-in iSight camera, taking screenshots, and turning on file sharing, not to mention transmitting system and user passwords.

SecureMac says the Trojan is currently being distributed from hacker websites and discussions on these sites suggest distribution through iChat and Limewire. Users must download and open the Trojan in order for their PC to be infected. AppleScript.THT is distributed as either a compiled AppleScript, called ASthtv05 (60 KB), or as an application bundle called AStht_v06 (3.1 MB). Upon download, the Trojan will move itself to the Library/Caches/ folder and add itself to the System Login Items.

The warning page advises users to run MacScan 2.5.2. Click here to read the advisory.

The warning comes the day before Apple patched a “Carpet Bomb” bug affecting users running the Safari browser on Windows and allowed attackers to download files onto a users desktop without their knowledge. Click here to read more.

    Its just going to get worse for the apple community because the bunch of them believe they are immune to virus, and spyware. Its a shame really. I mean me myself use Pc, and Mac, and work in the computer field. I Obviously know to actively use a real time scanning program.

    I i consistently try to tell people on what it seems like a daily basis,
    that something big will come and you might want to try and be prepared for it. All i recieve back is ignorant rants about, thats PC related problems, im on a mac, and I dont have to worry. Sheesh.

    People just dont get that the only reason you dont here about Mac viruses, and spyware is because the number of users to Windows is minscule, but thats changing every so gradually, and it will be bad
    for a lot of people.

    I feel so bad because Apple really doesnt actively push the software to
    prevent hard enough.

    "Users must download and open the Trojan in order for their PC to be infected."

    At least it's user friendly and they don't have to compile it from source code.

    Just exactly how is this a greater threat then any other user-installable application? Is adware acceptable because of it's profit? Is game DRM spyware acceptable because of it's license?

    wow that's funny. I just saw the Mac advertisement that says they don't have viruses. I'll stick with my PC because they have better tools at detecting and removing the viruses. Kudos to Neog2.
