People asking me for the anime lore on this LiteLLM compromise.

I'll do it tomorrow. It's got some filler episodes, but they're still lowkey important for later references.

The first episode is kind of cool, it slows down, but then toward the end of the anime it gets crazy.

In extreme summary, nerds compromised a thingie, used it to compromise other thingies, used that to compromise other thingies, then did the big thingie with LiteLLM

It's a big cluster fuck because now you're like, what did they steal? Do they have access to anything else? How long is season 1 of this anime? It's wild stuff

The LiteLLM supply chain attack is big shenanigans. I have to explain the whole thingie though so you can get the full context of the shenanigans. TeamPCP (the people who probably did it) is unironically swinging a big ass fuck off baseball bat, they're swinging for the moon.

tl;dr see picture of cat as summary

I also want to preface this with I DID NOT PERFORM THIS ANALYSIS. I almost never do open-source solutions malware stuff and this is also more in the line of work with DFIR (Digital Forensics and Incident Response). This summary comes from various peers and colleagues of mine who have been discussing TeamPCP the past couple of days.

DFIR nerds I sourced:
- ramimacisabird
- InsiderPhD

Non DFIR nerds I sourced:
- IceSolst
- IntCyberDigest

Yeah, so pretty much this group of nerds named TeamPCP bamboozled an open-source security product called Trivy. TeamPCP sent a pull request on GitHub but did it with "pull_request_target".

Normally a pull request isn't a big deal. Nerds do it all the time. "pull_request_target" though is designed to copy secrets, tokens, etc. pull_request_target is a legit thing. People do it all the time. It should only be performed by people you trust. TeamPCP impersonated a legitimate GitHub contributor.

Trivy was caught slippin'. When TeamPCP did pull_request_target they stole access tokens to a place called Aqua Security.

Aqua Security was like, "lol gosh dang it" and did what you were supposed to do. They rotated access tokens and passwords and stuff. However, Aqua made an oopsie and forgot to rotate the stuff for one of their automation bots.

Once TeamPCP had access they injected malicious code which steal environment variables, SSH keys, cloud credentials, cryptotokens, etc into three things.
- Trivy
- Trivy GitHub actions
- Trivy Docker stuff

As is tradition, once TeamPCP put malware into Trivy stuff, anyone who did anything with Trivy was given malware. TeamPCP got a metric poop ton of stolen data and began using it to move to NPM projects. The projects they infected next was infected with a malware people named "CanisterWorm".

In extreme summary, CanisterWorm placed stuff in package.json from the infected NPM project. Every new infected NPM project would download malware to the machine that (unsurprisingly) stole your data.

TeamPCP seems to have been inspired by the North Korean government, or ALPHV ransomware group, because instead of stealing data to their server they store it on the blockchain ... making it virtually impossible to takedown.

LiteLLM takes place somewhere between Trivy and CanisterWorm. As of this writing the exact way TeamPCP got access to LiteLLM is unknown, however it's heavily speculated it is from Trivy. TeamPCP also stated very bluntly they got access from Trivy but ... they could also be lying. This may come as a surprise, but sometimes criminals lie to cover their tracks.

LiteLLM infection though was a few more degrees amplified than the previous stuff. LiteLLM infection also attempts lateral movement by automating Kubernetes stuff. LiteLLM infection also steals a ton more data than previous stuff. Here is the big ass list of stuff it steals:

- SSH keys
- AWS credentials and configurations
- GCP credentials and configurations
- Azure environment variables
- Kubernetes credentials and configurations
- Environment configurations
- Shell History
- Git credentials and configurations
- Docker credentials and configurations
- Database instances
- IaC / CI/DI
- SSL private keys
- Solana keys
- Crypto wallets
- VPN credentials and configurations
- Hashicorp vault (?)
- NPM configurations
- SMTP credentials

TeamPCP is unironically putting in big moves. What makes them unusual is how profoundly aggressive they are. It isn't uncommon for Threat Actors to attempt things like this, but TeamPCP is doing something more akin to "smash and grab" rather than "stay silent and watch".

The past couple of months I've personally witnessed a few changes in malware that are so significant that it blatantly sticks out.

1. Malware written in more esoteric languages. I've witnessed a shift away from languages like C/C++ to languages that are heavily abstracted, most notably NodeJS with Electron.

2. A MASSIVE shift toward targeting open source solutions. While this isn't new, the past couple of months its been every single day someone is targeting a supply chain via masquerading or directly targeting the open source provider.

3. AI has assisted with the shift in the malware landscape ... toward higher level languages. I've witnessed a spike in multi staged malware using a lot of LOLBIN-like methods. Again, this isn't anything new, but I've witnessed such a dramatic spike I believe it is the result of AI making it much easier to create and use high level languages

4. The introduction of new threat landscapes: Clawdbot (or whatever it's called now). This has resulted in a shift toward MacOS malware which is referencing bulletin point 3. Heavy usage of ClickFix with high level multi staged languages (bash script to Js)

5. AI being used for social engineering. Historically I've seen really crappy malware lures and phishing pages. I suspect AI is helping polish pages and making them look more realistic, possess no typos, use good grammar, etc.

And for a bit of nuance, this is MY perspective. This is anecdotal. It's totally possible this is just what I'm seeing and it's possible the shift is much smaller than what I've personally seen.

We would need for a larger sampling size and study to be performed.

Windows Defender is very silly and I am flabbergasted.

I always keep Windows Defender off. As a person who collects malware, writes malware, and pokes malware with a stick, Windows Defender is a big stinky dork who isn't cool and gets in my way.

Earlier today I was doing big brain intellectual stuff that you wouldn't understand (watching police chase videos on YouTube) and suddenly Windows Defender began screaming obnoxiously loud into my headphones that it has detected hundreds of malwares on my machine.

Windows Defender turning itself on is no big deal. I keep my several terabytes of malware segregated (it's in a special folder that is whitelisted, I pray I don't accidentally detonate it). However, Windows Defender was screaming malware was in my C drive.

This is sort of weird ... I write malware, maybe it's flagging one of my proof-of-concepts as malware? Maybe?

I look inside and this fucking piece of shit is flagging my anti-malware project I'm working on as malware. That makes literally zero sense. Nothing in my anti-malware static analysis goofy project is even remotely malicious. What the fuck is this piece of shit yapping about?

In my malware static analysis project I extracted the YARA rules from Windows Defender. I use those same rules for identification.

Windows Defender flagged IT'S OWN RULES as malware because of the strings present in THEIR OWN YARA RULES

You dumb son of a bitch. I HATE YOU. Now I have to spend an extra FOUR MINUTES re-extracting your YARA rules and recompiling them for my project. HOW DARE YOU

LeakBase admin "Chucky" was arrested.

For those unfamiliar, LeakBase was this big ass fuck off website which sold, traded, auctioned, and freely distributed stolen data from compromised websites or companies.

LeakBase audience was primarily Eastern European.

Despite the wide spread identify theft, credit card fraud, extortion, initial access brokering, and money laundering that "Chucky" enabled, he was a nice guy.

I used to send silly pictures of kitty cats to him.

Was he a hardcore cyber criminal? Yes
Did he enable crime? Yes
Did he help facilitate crime? Yes
Did he aid and abet criminals? Yes
Did he give a platform to other criminals? Yes

But, did he have good taste in silly kitty cat pictures? Yes, he had very silly kitty cat pictures.
