What I find so impressive though is that this malware has been active on GitHub FOR A YEAR.

Dawg, they're banning security researchers and this malware has been present FOR A YEAR

I like writing malware because, instead of making useful and productive software, you spend an absurd amount of time writing a really over complicated and convoluted way to create a file.

A simple line or two of code becomes like 50 lines.

It's fun, I don't know why

o ok, thank god they removed it, i was afraid the knedliky police were gonna come to my house and beat me to death with knedliky

close one

Oh yeah? You're a "hacker"? Prove it.

Show me your $600 entry ticket for Slermie Doop 16 and massive collection of cybersecurity vendor merchandise you either received for free or purchased.

You're not a real hacker until you're a walking billboard for tech companies

Hahahahaha. What? You can't afford a ticket to Slermie Doop??? Sounds like you're POOR. Sorry, kid. We're HACKERS. We fucking HATE poor people.

Next thing you're going to do is say you can't afford the $2,000 Schmeemee certificate, proving you're a real hacker.

It makes me very happy receiving DMs of malware and people asking "is this goop?".

There is a real-world chance that we can fundamentally corrupt people to begin referring to malware as "goop", and making our entire industry look like a fucking joke

That's so badass omg

Chat, I'm unironically a big fan of AI now

I don't vibe code, or whatever, but it's ability to generate me slop Python scripts for reverse engineering, or it's ability to help me troubleshoot Linux gunk, is absolutely incredible.

I'll say, "Hey ChatGPT, I've got this goop that is doing X, Y, Z. Can you make me a Python script that handles it?".

My Python is trash, but ChatGPT is like, "I got you, big dawg", and gives me the thingie I need in just a few seconds, saving me tons of time browsing StackOverflow or screaming at my IDE about syntax issues.

Thank you, OpenAI, for giving me ultra mega slop Python maker 9000. It is incredibly helpful to me.

Oh, and I've never had OpenAI give me any warnings and stuff about potential violations or whatever. Anthropic complained all the time. I'm not verified by OpenAI as a cybersecurity professional, ... I just ask for slop Python and it produces magic. I don't know how it works, but it's cool and badass

Someone is DDoSing vx-underground.

This is terrible news. I was going to work on the website, but now all I can do is spend time with my family and enjoy a beautiful summer day

Terrible, this is just plain terrible

Welp, do your thing big dawg, hit me up when you're done

Hi

More malware has been uploaded to VXUG. It's like, 150,000 malwares, or something. I also uploaded more malware analysis papers.

Show it to your parents, they'll be proud of you.

I am filled with disappointment.

Last time on Dragon Ball Z, I announced my boredom with malware development, hence I decided to pivot to malware defense. I began by taking apart YARA to understand how it works, and making my own little silly YARA scanner. Whatever.

I then began reviewing the malware people discovered in the wild. I have reviewed hundreds of malwares, and many also non-malwares.

Unfortunately, I am at the point where I am no longer finding original goop. It is the same malware campaigns, different person sending it, different compromised webhosts, or slightly tweaked SHA256 hashes.

I now feel the existential dread my blue team colleagues feel. It is the same gunk everyday. The gunk is persistent. The gunk is infinite and vast. The gunk is like an ocean of gunk.

"What if we used AI to turn source code into a binary?"

Lots of stuff happening with vx-underground at DEFCON

It's all very confusing though because I don't go to conferences, and many of the vx-underground things occurring I was not informed of, or made aware of, or I literally don't even know what it is

So it's just kind of weird when I'm chilling and I'm notified like, VXUNDERGROUND THING HAPPENING AT DEFCON and I just stare at my screen like ?????

Then people message me if I'm at DEFCON and I'm like "nah" and then they're like "omg thank you so much for the goop" and they send me a picture of something I've never seen before, or a picture of someone I've never met in my entire life

I don't care, I just do malware stuff and collect pictures of cats, but it's all very confusing and it hurts my little brain because I don't go outside but apparently I (or my crappy project) is doing many things that I myself didn't know existed

Anyway, yeah I have no idea what's going on, I'm not there, I'm sniffing around the internet looking for goop

Them: "Great meeting you at DEFCON! Thanks for the stuff!"
Then: *Sends picture of people and stuff*

Me:
- I'm not there
- I don't know who you are
- I didn't give you anything
- I don't know what you got
- I don't know the people in the photo

Me: "No problem, bro" (I don't know what's going on)

dude, what in the fuck is this shit?

.vbs -> .zip -> .msi (files 1 - 6)

.msi_file6 -> msi_file4

.msi_file4 -> autoitscript

autoitscript -> .exe

.exe -> msi_file5

these nerds put in a significant amount of effort to make this as multi-staged and as convoluted as possible. this is 100% AI generated. they left the notes in place. however, based on everything i'm seeing, i think this person probably has a decent understanding of malware and understands how annoying this is

tl;dr not super sophisticated malware, but really fucking annoying

oh, and the files arent on VT, for my colleagues who care about weird annoying goop
