PowerShell MultiHack

Do you guys remember PowerShell MultiHack? I just want to know.. Is it still undetected?

From my understanding, it will always stay UD as it's core program is PowerShell and Valve can never ban PowerShell. I was using it for a good 4 months and I've never been vac banned. The real issue you should be worried about isn't getting vac banned, but getting overwatched or getting disconnected during competitive matches due to VAC unauthenticated.

I'm pretty sure Valve blacklisted Powershell which renders that cheat useless
