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 ugh now MS will disable the run dialog which is literally the only way i can survive using windows 10 or 11 for 5 minutes
@wyatt8740 @[email protected] shift + f10
opens cmd

you can also use task manager (Ctrl+shift+esc) and then go to file>run

and gpedit.msc can enable/disable run iirc

@Maven @kravietz yes, that is how it currently works.

But if this attack becomes common it might change more.
