Have a nice day

Today Linus Tech Tips released a video about the vx-underground harddrive and our collection.

First, thank you for using an image of a shadowy person with odors radiating off of them to describe smelly. 11/10.

Secondly, Linus and his group did an EXCELLENT job discussing the harddrive and the collection. We believe they accurately describe it, its use case, and the basic reasoning why this entire collection exists.

Some portions of the video are very watered down – but this high-level beginner perspective is perfect for people who are unfamiliar with malware. Additionally, in some places the nomenclature is wrong, but the general idea and principles are still 100% correct.

We also enjoy the enthusiasm Mr. Linus shows with the malware, he reminds us of our first time experimenting with a malware builder.

The end review saying we're the darker side of grey is a little disheartening, but ¯\_(ツ)_/¯

Every week nerds ask us "do you know {ransomware_groups} onion?".

Every ransomware group's domains are archived, past and present, as well as their post history by Josh Highet on his website ransomwatch telemetry.

Now stop asking us >:(

tl;dr video with 1,000,000+ views gets lots of attention

(we dont have any in stock so it doesnt matter)

It appears security researchers, not just sim swappers and fraudsters, follow us on Telegram. It's truly a Christmas miracle

(we don't know who did this talk or what it's about)

"i'm a noob, whats the best language to start maldev?"

Buy a dartboard, put stickie notes on it, write programming languages on them, cover your eyes, spin around 10 times, then throw the dart.

Whatever it lands on, learn that language and get good. If you miss, give up.

Lockbit ransomware group administrative staff agreed to go onto a livestream with us (us screensharing a Tox screen) and doing a live Q&A and allow the audience to ask questions.

Questions would be filtered, but maybe it'll be fun.

¯\_(ツ)_/¯

We caused some confusion about our RansomHub interview post because it was worded similarly to our Lockbit ransomware interview post.

It's a new interview – nothing is being cancelled. We'll mentioned it again later on so we don't confuse people.

Yes, we're aware of the OpenSSH exploit – "regreSSHion".

Everyone and their grandmother is discussing it, it'd be difficult to miss it. We didn't have anything meaningful to contribute to the conversation, so we didn't mention it.

tl;dr exploit bad, its monday, nerd stuff

stupid ai meme is kind of funny

Today RecordedFuture released a research paper on using malware infostealer logs to identify CSAM consumers.

RecordedFuture identified over 3,000 individuals purchasing CSAM. All users were reported to their respective law enforcement agency.

https://www.recordedfuture.com/caught-in-the-net-using-infostealer-logs-to-unmask-csam-consumers

The paper is profoundly interesting. Research indicates some users had multiple accounts across multiple CSAM sites. Using the malware stealer logs they were able to perform OSINT and tie them to real-world identities.

tl;dr being a failure is cool and badass

Failure is the standard for any sort of malware development, research, or reverse engineering. We think of ideas all the time, research them, work on developing them, then it implodes and fails to come to fruition.

Collectively, we've got dozens of failed, botched, or incomplete projects due to various setbacks and failures. Often times the code is scrapped, put on a metaphorical shelf, and hope the code will be of value sometime later down the road (sometimes years later, or never).

If you're new and you invested several hours, days, weeks, or months and your code ends up being a dead end: Welcome to the club.

Attached image is a screenshot of failed or incomplete projects. This is just the tip of the iceberg.

ChromeDumper - dumps stored credentials from Chrome like a generic infostealer malware. It used to work, but Chrome changes how it stores credentials fairly often, so stopped working on it

DataSharingMalcode - experimenting with various interprocess communication ideas.

Demo - Just shooting in the dark at random ideas. Experimented with things like CfOpenFileWithOplock instead of CreateFile. Lots of failing

DiscordSecrets - Disassembling the Discord binary and inserting malicious payload into it. Sort of works, stopped caring

DiscordExfil - Using Discord as a C2 using webhooks. Works, got bored with the idea

Dll1 - Throwaway DLL for debugging

EtwKeylogger - Experimented with keylogging using ETW. Someone else did it, couldn't reproduce it, gave up

FirewallAPI - Various experiments with using Windows COM to disable or alter the Windows firewall. It works, but got bored with the idea, moved on. Buggy code.

InMemoryJsExecutor - Uses Wnoscript engine to execute JS and VBS in-memory. It works, is buggy and unstable.

KeyboardTsf - Experimenting with keylogging using Windows Text Service Framework. It's a huge pain in the ass and requires a lot of external factors for it to work.

LetsGetWeird - Various attempts at abusing random Windows APIs for loading or executing binaries. Some of the code has been added to VXUG

LsassDump - Experimenting with dumping LSASS. Some of it is reproducing or testing others works.

Matroyshka - RecursiveLoader version 1. It's a piece of junk

Packer - Inserts malware into a section into the target PE file. Modifies entry point to jump to it. It works, can be unstable. Got bored

PancakeWare - Experimenting with file compression, some have been added to VXUG, most fail

SpywareVideo - Experimenting with turning the camera on a PC like old school RATs do. Got it working, but got bored.
