Chat, we are cooking.

Previously on Dragon Ball Z, someone DM'd me a spoopy GitHub they found. They asked if it was malware. It was malware.

The GitHub contained HEAVILY obfuscated Lua. The malware payload is using Prometheus Obfuscator.

Upon review, it was determined this malware is SmartLoader. SmartLoader is a malware campaign heavily associated with Rhadamanthys Stealer and StealC Stealer.

SmartLoader is relatively new and is being tracked by AhnLabs, TrendMicro, Hexastrike, McAfee, and the GitHub security team. It first emerged around March, 2024.

SmartLoader is pretty sophisticated. It is multi-staged, uses Polygon Smart Contracts for C2 information retrieval, and despite being Lua, it is also makes usage of NTDLL makes low-level WINAPI function invocations. One interesting attribute also is it programmatically inflates or deflates its file size for pseudo-polymorphism. This is extremely cool.

I mention this, and the whole cookin' thing, because after I made a post complaining about the obfuscated Lua, a very, very, very gifted person in Lua obfuscation and de-obfuscation contacted me and successfully deobfuscated it. I don't know if they want credit or not, because they're so cool and badass, but they're extremely famous in the Roblox hacking scene.

Anyway, the de-obfuscation is so precise it borders on having the actual source code to SmartLoader. I am very happy. I will share it when I am not dealing with my baby.

I've almost reverse engineered the SmartLoader obfuscated code all the way down to a working source code

You can't hide behind Prometheus you little bitch

I'm sorry, SmartLoader malware campaign, I shouldn't have called you a little bitch. That is very rude of me.

I am just passionate and have spent some time working on it, so my emotions are high.

I love you.

My deepest condolences to my colleagues in Venezuela and those impacted by the recent earthquakes.

I wish I had more to offer other than words. I hope you're all doing well and I hope you're all safe.

my brother in christ, if your company ran this .exe from this vendor, you better call someone ASAP because your company is COOKED. also, this vendor is either a criminal enterprise or compromised. gl big dawg. happy monday

Chat, I don't want to jump to conclusions, but I have a sneaking suspicion this malware stager was vibe coded. Historically, malware hasn't left extremely descriptive comments in their stagers.

omg i got FREE malware from REDDIT

I tried to do a write-up on X and share some de-obfuscated malware source code

I kept getting notifications on X saying something like, "sorry—something has gone wrong, don't fret", blah blah blah.

If I removed the malcode it worked

I THOUGHT THIS WAS AMERICA

THEYRE PREVENTING THE PEOPLE FROM GETTING MALWARE!!!!!!
