Powershell Deobsfuscation Ep.7

Team, has anyone ventured into PowerShell Deobsfucation yet? I’ve got to 7 no issues but I cannot get another further. The drama is every time you reset it’s a completely different code or it freezes...

    Hello - the labs use "invoke obfuscation" which is why they are different every time. They are really difficult, it took me a month to complete them.

    Have a look at some internet articles - this is a good primer

Hi Jay,

What tool or approach you use is very much a personal choice, but CyberChef is very powerful and flexible as you can tweak and fine-tune your recipe and see the results in real time.

Out of interest, have you looked at the 'Introduction to PowerShell Deobfuscation' collection?

If you continue to struggle then let me know - I'll be happy discuss approaches in more detail.

Cheers,
Barny
