Chat, this is yet another Threat Actor using AI to slop up some malware. The only difference is this Threat Actor used professional level tools (although trial version) and put slightly more effort into the C2 and masquerading stuff.

If you'd like to see the source code I've reconstructed (and slightly more verbose writing), see post below this one.

I'm a big fan of Windows 11.

One of my favorite features, which really boosts productivity, is the UI crashes (explorer), and whatever UI element was highlighted is now forever stuck in-memory.

"Copy" is stuck in the middle of my screen. I won't go away.

I love it.

It also overlays other UI elements. This is amazing. Look what I see when I open Telegram

A colleague of mine notified me of actual super rare mega fuck off ultra malware identified in the wild.

He said the malware is sophisticated (by my standards) and has proven to be incredibly difficult to reverse engineer. He asked if I felt like trying to bonk it with a stick.

Chat, can I bonk the sophisticated Threat Actor malware with a stick? This malware is believed to originate from a well-known and very active Threat Group, which has posed a significant threat to vendors and consumers, for quite some period of time. Their new malware strain is believed to be augmented by AI, hence improving their malware development lifecycle and introducing enhanced capabilities.

I guess we'll find out later tonight, or tomorrow, when I get a chance to look at it. We'll review it and see if the hype is real, or if it's just malware goop.

Had a lovely conversation with a Threat Actor from South America.

It turns out, one of the malwares I bonked with a stick was written by someone who follows this social media profile. They confirmed to me in private it was primarily written using ChatGPT.

We had a cool conversation though, last week bro made about $54,000 from his various malware campaigns he spreads on Discord. He was not lying about his "income". Crimes does indeed pay.

He also has a pretty nice computer setup.

We also made small talk about how to illegally immigrate into the United States for as low as $400, problems with money-mules and credit card fraud, and his opinions on other South American countries (he doesn't like Colombia, he says they're not good people).

Overall, bro was pretty chill, despite the large scale identify theft, extortion, money laundering, tax evasion and possibly illegal immigration he does.

I keep having noobs message me and call me a hacker and ask about computer exploitation

Dawg, I am NOT a hacker, I'm not memeing either.

I can write malware, reverse engineer malware, bonk stuff with sticks. But, if you asked me to move laterally in a network it would take me 6000 hours.

Likewise, I know nothing about web exploitation. I couldn't compromise a website if you gave me the username and password

I'm just stinky malware man, I am not cool and badass hacker man.

I've been bonking this malware with a stick for over an hour, I think, maybe two hours. I've been able to grab an in-memory mapped PE file which the original .exe loads into memory. However, I am unable to determine precisely where this PE file is mapped exactly because it's a Delphi TForm application, its statically linked, and is intentionally obfuscated.

This secondary .exe loaded into memory has tamper protection, patching it to force itself to give me more malware won't be easy. This binary also has anti-VM features as well, I think from calculating disk space. However, I can't tell right now either, but this is what it appears like based on the API it imports.

1. Delphi TForm application
2. Does stuff, lots of junk
3. Maps secondary PE into memory (somehow)
4. Secondary PE does recon to assess the machine
5. ???

Somewhere in the midst of this, this binary is going to make an external call, somewhere, somehow, but it's proven to be difficult due to how obfuscated this code is, coupled with the custom PE cryptor, decoy data present, ... and everything else.

Initially I was under the impression one of the obvious .EXEs I saw was the actual secondary payload, but it's not (I think?), it appears to be a decoy (I think).

I don't know who wrote this, but this is probably one of the most sophisticated malware payloads I've seen in recent time.

It has successfully evaded my VM, RecordedFuture Triage, VirusTotal VM, and AnyRun

I still don't know what this malware is trying to do.

This super ultra mega rare fuck off ultra malware my colleague sent me has a really fancy schmancy anti-VM feature. It is the fanciest I've seen to date. I like it.

After bonking this goop with a stick, sifting through dummy and decoy data, I figured out how they evaded my VM, RecordedFuture Triage, AnyRun, and VirusTotal.

They made a really fancy entropy thingie by collecting a bunch of data and doing fancy math.

I respect it.

🍞BAKING 🍞

I had a ton of people ask me about the super cool and badass malware sample my beloved colleague sent me. I also had a ton of people me to share more details on it.

Here are some FAQ:
1. What does it do?
It's an Information Stealer, but it's super fancy

2. Does it have a name?
Yes, as of like, last Tuesday (I have no idea when it was named, I'm just talking shit). It's officially called RevStealer by my peers. There is limited information it at the moment.

3. How long have you been bonking it?
I invested about 4 hours over the time span of a few days, I think. I wish I had more free time for bonkings, but I don't

4. Can you share it?
Yes, I am sharing it now. I'm pushing it to prod now. It's under /Samples/Families/RevStealer. I encourage you to bonk it too. It's really cool and fun to explore. I haven't had enough time to explore it and appreciate it, but I enjoyed it.

5. Can you share hashes?
Initial .zip:

Stage 2 (in-memory payload):

Decoy (maybe?):
851383fb22dcb1d16367839178271eef6504199b8ca60405e1698879696e49d4

6. Who is it attributed to?
I have no idea. My colleagues have speculations, but nothing is solid yet.

Pic unrelated (or maybe it is).
