Potentially Malicious Windows File Extensions Listing

I just stumbled on this very handy listing of almost every known Windows file types that can be used to compromise a Windows box in one way or another. It's pretty ironic that this document has been made using Word because a vulnerability that allows attackers to install rootkits on a computer via Microsoft's Word was discovered on last Thursday. Don't worry, this file isn't part of the problem; its part of the solution. It contains over 200 file extensions and provides you with all the details needed to help you make an enlightened decision about whether you should block them or not.


  • So, pretty much every filetype known to man... ;)

    Try this site for looking up unknown files/programs that are running (try typing in something like svhost).

  • Nice little find jono! I checked a couple of file names and extensions and most of them were right on the spot concerning security issues, except a few..

    like .bat and .cmd: "This file is usually safe"

    I guess we could say they are safe, but only if they come as a part of windows, or if you made them yourself. The same goes for .vbs files, they can be safe, but a lot of time, they are not.
