In internet security news today it has been discovered there is a new Mac malware threat – The Trojan horse “Flashback” masquerades as a Flash Player Installer which when downloaded deactivates some network security software and injects malicious code into applications that the user launches.
The malware spreads via malicious websites which include links inviting you to download the most recent version of Flash Player. When clicked, the link downloads a typical looking Mac installer package and if you use Safari the installer will open automatically.
If you recently updated Flash on your Mac you can check to see if you are infected by checking to see if you have the file: Library/Preferences/Preferences.dylib
The Mac Security Blog Intego offers the following advice:
• Users should not download a Flash Player installer from any site other than adobe.com. Users who wish to install this software should visit Adobe’s website: http://www.adobe.com/products/flashplayer/
• If you use Safari as your web browser; uncheck Open “safe” files after downloading in the program’s General preferences. This will prevent installer packages—whether real or malicious—from launching automatically.
• If an installer claiming to be a Flash Player installer appears, be very careful to ensure that you did, indeed, download it from Adobe’s web site. If not, quit the installer.
