Once installed on a system, Backdoor:OSX/XSLCmd wait for instructions from a remote server and execute them on the infected machine.


The F-Secure security product will automatically remove the file.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

Backdoor:OSX/XSLCmd appears to share a significant amount of code with the XSLCmd backdoor previously known to target Windows systems, possibly indicating that the backdoor's authors have expanded their targets to include the rival operating system.

Once installed, possible actions carried out by the backdoor include installing other programs, steaking files, logging keystrokes, capturing screenshots and updating its own configuration. Captured information is forwarded to a remote server.
