My internet connectivity has been absolute dog ass for years. I've been using this old ass fuck off modem and router combo. It was like, 10 years old.

I went to the local poopy pants store (computer store) and purchased this stupid expensive modem router combo thingy that looks like its from the year 3035

Dawg, I'm getting 2Gbps down 😭

Before I was getting 25 Mbps down (if I was lucky). I never even questioned why my connection was so slow despite paying so much money. I was too focused on cat pictures and malware to think good

tl;dr im dumb as hell

As is tradition, 4chan is doing some trolling.

They've launched "Operation Clogged Toilet".

They're intentionally reserving flights (prior to payment confirmation) from places such as India to the United States to prevent potential H1B holders to return to the United States

Yesterday a video game streamer named RastalandTV inadvertently livestreamed themselves being a victim of a cryptodraining campaign.

This particular spearphishing campaign is extraordinarily heinous because RastaLand is suffering from Stage-4 Sarcoma and is actively seeking donations for their cancer treatment. They lost $30,000 of the money which was designated for their cancer treatment. In the steam clip their friend tries to console them while they cry out, "I am broken now."

They were contacted by an unknown person who requested they play their video game demo (downloadable from Steam). In exchange for RastaLand playing their video game demo on stream, they would financially compensate them.

Unfortunately, the Steam game was actually a cryptodrainer masquerading as a legitimate video game.

Previously we made a post about a cancer patient being a victim of a malicious Steam game. It is a cryptodrainer masquerading as a free-to-play video game.

Based on reports and conversations occurring online, this is the malicious video game:

However, it is important that I note that I have not personally reviewed the game yet to determine if this is actually malware. This is what the victims allege or believe to be the culprit.

I guess we lookin' at this mfer fr
Chat, I'm not video game developer, but this file looks strange. Why does this video game contain a .bat file that looks for your browser credentials and crypto wallets?

Dawg, why did these cryptodrainer nerds leave their Telegram credentials exposed in plain text in their drainer?

dawg, you have to write better malware. took less than 30 minutes bro. you gotta lock in

Okay, I'm done looking at the malware. I enjoyed reversing it and looking at it. I've got stuff I gotta do now though.

Interesting technique by "David" to hire someone from Telegram to make the video game. I never considered this as a TTP. +1 cat picture for the clever idea.

-1 cat picture for using generic malware. This is probably some DaaS or ChatGPT malware. Makes use of Python and .BAT stuff.

-1 cat picture for draining a person with stage-4 cancer. That is really fucked up bro.
