    That´s why Windows PowerShell should be locked down on every system. :)

    yhnnhd1, first, welcome to Wilders! Because it's against our Terms of Service, posts directing members to malware, would be removed. Just FYI.

    Greeting. May I know how to config Windows or use security software to protect ourselves from Windows Powershell attack.

    Thank you.

    @ southcat

    I'd say have an App that Prompts you to run rundll32.exe & also helps prevent code injection. For eg, i have ProcessGuard which does both, & Zemana which does the latter too.

    Thanks for advices. I have used Process Guard long times ago until the developer stop it, I have installed Comodo and Spyshelter in my computer and i guess they do the same things ?

    Regards.

    Would EXE Radar Pro protect against this as well?
    Because rundll32.exe is by default in Exe Radar's "Vulnerable Processes"

    Yes, ERP can stop malware (and other apps) from using the Windows PowerShell.

    That´s why executable control (and white-listing) is so important. :)

    Yet another example of how XP "can be made" to be more secure overall than MS OS's since, in the right hands. Largely on account of being able to make the attack surface nearly non-existent with some tweaking. I don't have Powershell on my box at all, so this is all moot to me. .NET FW exploits, also rendered moot. And the list goes on and on... And I won't even get into the privacy side of things... there's no contest there.

    Modern OSes can be made even more secure. ;)

    Check out this thread:

    -http://ssj100.fullsubject.com/t7-blocking-powershell#3551-

    Both powershell.exe and powershell_ise.exe should be blocked.

    I suppose this would stop such an attack. :)

    They arrive more secure in some regards, not so much in others. But you're very limited on being able to "make" it anything it isn't already in out of the box, which I don't like. XP I can trim so much I'm left with basically nothing but the stump left, and it still works. Trim even a leaf from 7/8 and something is broken it seems. Also, I consider privacy and anonymity part of security. Not a fan of backdoors either, which I suspect all modern OS's have. That last bit is of course pure speculation.
