A sort of small, sort of long, observation or note, or something.

tldr nerds mad, touch grass

The internet (and humans in general, I suppose) love negativity and drama. There becomes a point though where negativity goes beyond spectacle and entertainment and it bleeds over into public anger and mass hysterics.

While I don't traditionally make political commentary (or try to rather, I'm human, make mistakes, or accidentally present bias), and stray away from political banter, my curated and compartmentalized information security feed has transformed into some pretty nasty dialogue regarding the recent United States governments actions both domestic and abroad. While some of my peers engage in political banter, an upward trend being observed, whereas even the "non-political" begin discussing things, is paramount and is an indicator that a profound event has occured.

This typically results in me saying "huh?" and acting like the cat in the attached image below.

Outside of this bubble I've made, it is chaotic (I'm sure you're well aware of what I'm addressing at this moment). Historically, it is unusual for this degree of anger and frustration to bleed into my bubble, previous and noteworthy "bleeds" include Mr. Rittenhouse, the death George Floyd, Ukraine-Russia conflict (beginning), Palestine-Israel conflicts (elevated, major event occuring), the COVID19 pandemic, January 6th, the assassination of Charlie Kirk, ... and now the recent events occuring.

I think being exposed to this polarization for too long is unhealthy, it makes people angrier, and deepens a divide. It's important to remember that political commentators profit off of outrage, it boosts their engagement and advertisement revenue, thus want to continually stoke the fire and ensure you're perpetually agitated.

I unironically recommend my colleagues and peers to touch grass. Disconnecting and disengaging with the internet hate machine puts things into perspective. Hug your children, pet a kitty cat, eat some junk food, go for a walk, ... do something other than being angry on the internet. There is a difference between being informed and being drawn into the political "event horizon".

Okay, back to kitty cat posting until morale improves and also nerd stuff.

I unironically perceive myself and you nerds as like, a bunch of old ass monks or priests or something, up on like High Hrothgar.

Person on YouTube uploads a video that is 114,115 years long (1,000,000,000 hours).

The video is (probably) a One Piece anime review.

Watched police body cam footage of a guy who robbed a bank. He went in with a gun, a slid a piece of paper telling the bank teller to give him all the money.

He received over $1,000 in cash. He was caught moments later. He is in jail and is facing over 20 years in prison.

The ex-mayor of New York pushed a "NYC Token" cryptocurrency and rug pulled over $3,000,000. He doubled his net worth in just a few days.

Nothing will happen to him.

Today I experienced something I had never imagined myself experiencing.

My 9 month old makes a big mess while eating. He is still learning coordination to self-feed. He's improving. I'm proud of him.

Today he made a gigantic mess while trying Jello for the first time. He decided to put it in his hair and also his pants. We're still not sure how he got the Jello so far down his pants ... but he did.

We had to wash him. He was sticky and stinky.

Because he's getting bigger he gets the "big boy tub". In essence, my wife or get in the bathtub with him and bathe him. We set him in the tub and we both wash him. The parent in the tub with him holds him, rotates him around to get the hard to wash spots, or keeps him distracted by playing with him. He loves splashing the water.

Anyway, today when I was holding him he took a massive shit in the tub. I'll spare you the details. I wasn't angry, ... but being a first time parent has been a unique experience none of the books or classes prepared us for.

That's all. I just wanted to share that with someone.

Today Spaniard authorities seized 10 tonnes (metric tons, 22,000lbs, 10,000kg) of cocaine being smuggled into the country from Brazil.

The cocaine is reportedly valued at enough to purchase 3 DDR5 RAM sticks and maybe a few Claude tokens

I need help.

My 9 month old son loves Ms. Rachel. For the past 3 days I've been subjected to cruel and unusual punishment. I'm trapped. I'm stuck listening to this lady sing "Wheels On The Bus" for, at minimum, 8 hours a day.

My home is a CIA torture black site. "thE wHeElS oN the BuS gO rOunD n RouNd" ... in the morning... in the afternoon... at night ... when he's trying to sleep or he's sleeping.

I'm at the point where I'll start confessing to crimes I've never committed to make this fucking song stop playing.

I've decided to poke MalwareBytes with a stick.

Why? I'm mildly curious how it works internally and I'm curious if I can produce malware custom tailored to evade it.

Why? Because sometimes I get weird ideas and want to do weird things for literally zero reason other than "sounds kind of cool".

I setup a VM for the first time in years to poke it with a stick. I didn't want to install an AV on my main machine. Yes, I will do malware analysis on my main machine but not install an AV.

After installing MalwareBytes, skimming some of the files, poking random things and saying "wtf does this thing do", I've learned some mildly interesting things but nothing revolutionary.

1. They use Jenkins for continuous integration. Does this mean anything? No.

2. Based off my minimal testing, I don't see any DLLs injected into binaries when they're loaded into memory. However, the binaries I tested are well known and well established. It might inject DLLs into unknown binaries.

3. MalwareBytes main binary is written in C#.NET. It loads a secondary MalwareBytes.dll which then displays everything. It does the same stuff Microsoft Copilot does. That is how MalwareBytes has a fancy UI and stuff.

4. MalwareBytes stores very little in HKEY_CURRENT_USER making tampering from user mode kind of hard. It's just basic settings and stuff.

5. MalwareBytes has a custom protocol handler of "malwarebytes://". It looks like it uses this for interprocess communication between other MalwareBytes modules and binaries

6. MalwareBytes ships with a (basically) blank DLL called "Sample.dll". I have no idea why.

7. MalwareBytes has 2 mini filters in place which (presumably) are the main thing responsible for detecting malware. This is standard. MalwareBytes Chameleon (one of the minifilters) looks like it's meant to prevent tampering with the actual important MalwareBytes minifilter.

8. MalwareBytes Chameleon looks like it's responsible for communicating with user mode and kernel mode components. It looks like this is done so user mode components don't communicate directly with the minifilter responsible for actually detecting malware

9. I have a lot more poking to do

10. There is a binary called "assistant.exe" which loads "assistant.dll" (more .NET) stuff. It may possible to abuse this as a LOLBIN (maybe, need to poke more, kind of). assistant.exe does things like issuing commands for scanning, updating, and displaying things in the MalwareBytes UI. It accepts commands as "assistant.exe --uri malwarebytes://"

11. I have no idea how their scanning works, but it's labeled internally as Hyperscan

12. There is a thing called ProtectedHashes. I have no idea what this is.

13. There are tons of SQLite libraries, but I have no idea what it's for. Presumably, it's for known-good and known-bad file hashes, maybe? But I have no idea where this is stored.

14. I like cats

Poking MalwareBytes with a stick continues. I fell down a weird rabbit hole.

MalwareBytes contains a file that is packaged with it called "malwarebytes_assistant.exe". This file is written in C#.NET, it subsequently loaded malwarebytes_assistant.dll.

As the name implies, it is indeed an assistant file. It accepts commands and does things based on the commands given to it. There's a lot of commands, but here are the interesting ones.

- AddExclusion (can't find it though)
- Deactivate
- DisableWebProtection
- StopService
- LaunchProcess
- SetRegistryValue
- CreateWFCRule
- ModifyWFCRule
- DeleteWFCRule

LaunchProcess and SetRegistryValue check the parent process of the invoker. If it is not from a process that is signed by MalwareBytes, it fails. However, everything else works. It does prompt UAC, but it says its coming from MalwareBytes.

tl;dr disable MalwareBytes, modify Windows Firewall, etc. It displays as MalwareBytes doing it.

We must continue poking it with a stick.
