The kids are making anti government surveillance memes and I love it.
If this were a meme made by someone in my age group it would be something like, "how I walk when I have hemorrhoids"

Administrative update:

1. I am going to begin the process of thanking people for malware submissions and/or papers and/or recommendations. They will be placed somewhere on the website. You can exaggerate yourself on LinkedIn and say you're a collaborator.

2. I have a large volume of malware papers and malwares in queue. It is 175,000 malwares, 20 or so papers. As is tradition, malware analysis will be coupled with the papers too. That is expanded every month as new material comes in.

3. I have no plans to resurrect the virus exchange for the time being, unless someone (preferably a large company) is willing to bank roll the entire thing. I can provide the malware goopies, but computers are expensive.

4. Per request from OG vx-underground nerds, in more serious posts discussing technical topics, I will drop the silly cats and instead revive the classic edgy vx-underground dark. I will introduce a balance between seriousness, and edgy Hot Topic Goth, and generate kitty cat stuff.

Thank you everyone for the love and support. I see your messages and e-mails. I am enjoying the summer with my son and family, so I am simply less inside at the moment. I will (hopefully) do more malwares soon.

Oh, I forgot. One other thing.

I had a few people say I should focus more on news. People said using keywords like "breaking" can improve engagement and potentially bring more people to this social media account.

I appreciate the insight, feedback, and thoughtfulness. However, I am very much ... I don't know the word ... I guess I don't really give a fuck bro. Yes, people and monies and stuff is cool, but I don't want to be a slop account. I'm just going to continue doing what I'm doing.

Malware source code, samples, and papers for free, forever.

Cheers

Have you ever accidentally lost 50,000 malwares?

I downloaded 50,000 malwares and I don't know where it went.

No, I'm serious, I actually have no idea where the malware went. I'm confused and scared.

Have you seen my malware?

Hello, People Living Inside My Computer (PLIMC),

If you're someone who enjoys malware, I have good news.

If you're someone who dislikes malware, I have bad news.

I have uploaded 176,000 malwares and some malware papers. Please download it.

Found a compromised website with ClickFix that successfully bypasses uBlock. The ClickFix payload uses LOLBINs and uses a WebDAV server. It was promising.

The C2 is dead.

Wait, no. The C2 domain changed and the C2 blocked my IP.

Give me your goopies.

We desperately need someone to update noob malware literature.

The shit for malware noobs looks like it was written in 1995 and by someone who doesn't know shit about malware or how it actually works.

It reads like someone describing swimming who hasn't ever been in a pool

As an example, if I search "malware intro", the first page is from CISCO. CISCO writes that there is seven different types of malware.

- Virus
- Worm
- Trojan Virus
- Spyware
- Adware
- Ransomware
- Fileless malware

These definitions are too vague, I think a better explanation (although a little bit trickier...)

- Infector
- Stager
- Module
- Stealer
- Spyware
- Ransomware
- Loader
- Toolkit

However, this doesn't accurately capture the nuance of web based malware or IOT and/or ICS/SCADA malware.

I'm pretty impressed. The past four malware goopies people sent me were partially AI slop.

Despite them being AI slop, they were still relatively effective and got the job done.

If AI is helping the noobs, imagine how much it's augmenting the actual skilled Threat Actors

Yesterday I was experimenting with using X articles for sharing malware bonkings. People wanted me to be slightly more verbose, primarily out of curiosity.

It was cool. However, for reasons I don't understand, the X algorithm doesn't do much for highlighting articles. I was under the impression they wanted people to write articles. When I used their article thingie my engagement was through the floor.

I don't understand how any of this works.

Regardless, with X articles it isolates the homies on Telegram (they're probably all criminals, I don't know, Telegram nerds are schizos).

Moving forward I'll probably just link to my goofy ass blog. It'll also make it easier for people to find it in the future (if they even care). I'm aiming to make them short, entertaining, and (hopefully) educational.

Thank you to the people who continue to send me free malware. It is cool and badass.

Hello mystery mini-people living inside of my computer. I want to speak into the void. You probably don't care, but I would like to share something with you.

Today I was hit in pee-pee so hard I thought I was going to die. I've been hit in the pee-pee area before, but this was like ... I was completely incapacitated.

I fell to the ground and began screaming like a sissy. I couldn't breath or move for like, 5 minutes probably. I couldn't breath, my stomach hurt for some reason, my pee-pee area was cramping. I don't know, bro. I've never experienced pain like this.

I got up and limped my soft squishy body to bed. I laid down in bed for over an hour and my pee-pee spot still hurt. It was pulsating, kind of swollen.

I ended up going to the hospital and ended up getting told I've got Testicular Contusion with probable soft tissue damage to my string thingies.

Will I die? No. Was it the most painful oof owie I've ever had in my pee-pee spot? Yes.

I guess basically what I'm trying to say, if you have testicles, you should not bruise them (contusion). It hurts really, really bad. It will literally ruin your day.

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.
