2026-07-22 - Free AI goop (malware source code)

As is tradition, someone DM'd me on X (the everything app, but not really). They said their box was infected with malware and linked a Triage report. The report was ... meh. It was a typical emulation report. It gave a brief overview of it worked but I wanted more.

"sorry for the header but I’m hoping it got your attention among the thousands of DMs you get. Eric Parker recently made a video talking about a typosquat domain that was impersonating christitus’ tool “winutil”. I was the one who reported the typosquat to Eric’s discord, in which an analyst named Flamma (thisthinkletsyouusereallylongnam is their full username) helped me analyze it." — guy on x

Okie dokie.

Original report with SHA256 and stuff: https://tria.ge/260709-zhnv3sav51/behavioral1

tl;dr PyArmor stager followed by PyArmor payload, likely all AI slop, reverse engineered payload has debug statements, print statements, and super repetitive code which no actual malware developer would do. Despite this, it appears these Threat Actors have had moderate success.

This person downloaded "Update" which was a .zip file. It is masquerading as WINUTILS. It has a PyArmor encoded .py file

This is a very silly file. They used a trial version of PyArmor. I guess we'll bonk it.

I bonked it with PyArmorOneShot (I named my directory "aaa", I'm lazy)

We get goop:

Neat, we've pulled a thingie out of SysMon.py.

The result is a botched .py file and the raw instructions to SysMon.py (from PyArmor). The main thing of value is this silly guy:

tl;dr it's downloading this:

getthemff ... very cool, I guess...? I guess we'll download it

It's free malware. However, it is MORE masquerading malware. It contains more PyArmor stuff. It is also a trial version (again). I guess we'll bonk this now too....

So... we've got some password stealer stuff, some wallet stealer stuff, ... lots of stuff actually...

I got the PyArmorOneShot .das (raw bytecode) and coupled with the PyArmorOneShot .py and AI slop machine, I was able to reconstruct their stuff back to original source code.

Auto-fill Stealer:

Utils:

Discord Tokens:

The main stager also has something with Minecraft in it, it also drops XMRig somewhere in this piece of shit, and some basic machine identifying stuff and persistence using Windows Scheduled Tasks. Now that I've reversed a big chunk of it I'm pretty bored.

They also named some files "nig". ???
