back to article Bish, bosh, Bashware: Microsoft downplays research on WSL Win 10 'hack' threat

Microsoft has downplayed the risks of running a Linux Bash shell command line on Windows 10 via its Windows Subsystem for Linux (WSL) feature after security researchers said the technology could help hackers smuggle malware past security scanners and onto Windows 10 machines. Researchers at Check Point say that a potential …

    No need for funky exploits. You simply write a script that pwns the machine (download and install TeamViewer or a keystroke logger if you are real l33t) and claim that it is actually an AD or WSUS maintenance script and slap it on a blog somewhere. It'll be copied and pasted straight into the console so many times without question, you'll have a botnet in no time. Now I don't have to learn PowerShell to do this - I can use my long honed unix sysadmin script writing skills.

      So if we're being FSF-ish, surely it should be a GNU system for Windows. Something like GNU/Windows perhaps...

      Mine's the flameproof one, thanks.

        AIUI it's a facility to translate Linux system calls to Windows kernel calls in order to run the Linux userland - the converse of Wine.

        But I like Gnu/Windows. As soon as the marketroids mis-hear it it will become New Windows.
