No, this is no a new CAPTCHA, this is a new malware vector which tricks users to open #Windows command line and paste a command to download some harmful stuff.

Just reported by Mohamed Aruham on Twitter.

Interesting vector, ever seen this before @_JohnHammond?

@kravietz I don't see how something like this would work on #Linux.

Let's say you achieve this. You copy text for bash commands. It would have to be a long ass string of commands and if it needs something to be installed, you would need to elevate your privileges. It won't allow any program or any script to run.

This is a uniquely Windows problem, IMO.

@joelpomales
most linuxes have curl and you can rely on a posix-compatible shell under sh, curl blablahblah |sh for getting the real long string in
