John, you are an amazing Fella who always makes AAA+ quality videos! Huge props to you!! 😊 I really have obtained lots of knowledge from your videos!

Already stopped the same attack thanks for this. Also did the malware analysis of the .ps1 file.

Love this content! Thank you for the analysis as always ❤️

18:35 That looks like someone actually modified the malicious DNS record instead of just removing it XD

Thanks man!!

That UUID at the top of the script in the registry is probably to change the signature of the script.

Powershell stuff is interesting af

13:01 and I'm here for it

I had this too and not sure where I had gotten it.

How did you get to stage 2? Did I miss something? These ps1 scripts are just reading from registry and getting values. What values are they getting?

So after the first stage ran, it output a base64 code. He decode it and it shows a block of code. That code is the second stage.

How are they injecting and running the PowerShell? It feels like we’re missing the initial attack.

Temp files/adware/malware. Unprotect your computer and visit as many fishy websites as you can. Then turn on your protection and watch it pick up a bunch of stuff in your temp folder.

thanks

Great master

coolbase64 package for sublime would be useful for this kind of stuff since you do a lot of decoding ,you can just select and decode in sublime directly

For a moment there I thought scambot (EDIT: now banned and deleted) was doing a ^this style comment to reaffirm your suggestion. Which very well may be the first and only actually useful thing it did.

aaawesome !!!

uuh, wtf. I found this on a pc two weeks ago, 3 PowerShell files with a name of 4 random characters with the exact same contents. I correctly identified it as a virus and did some research, after deleting it there still remained some other parts which I could not find (I am a noob on this), so wiped everything. Amazing to see a video on it

Why they store payloads as byte arrays?

Ingress/egress by DNS is so brutally annoying!

Mind-blowing how these files brutally murder PowerShell. Even if you think about creating a file that doesn't make sense, to help disguise the malware, these scripts are terrible.
