My goofy ass website gets 142,000+- unique visitors a month. Dawg, I have GOT to find a way to monetize this without dropping to my knees and begging like a dirty scoundrel on the internet.

I've worked on this gunkie slermie everyday for 7 years. I gotta do something

Meta is still having some minor security problems. Instagram is currently exposing phone numbers and email addresses associated with accounts when trying to perform a password reset

This is cool and badass because everyone is sharing Mark Zuckerbergs phone number right now

I considered sharing the screenshot, but from what I've seen and heard, Instagram are severing the heads of people who post Marks phone number. I've seen a few X accounts get suspended

Silly shenanigans indeed

I don't know the whole lore, but nine crypto drainers and/or sim swappers have been apprehended in the UAE.

According to Threat Actors, cryptocurrency nerds (including ZachXBT), the people in the UAE are being tortured.

The full extent is currently unknown, however it's been reported the UAE government has broken their fingers, pulled their teeth out with pliers, and beating them in detention cells. They're still locked away.

These nine individuals have been in Dubai flexing expensive watches, partying with models, showing off expensive cars, etc. None are citizens of the UAE.

I don't know what they did to make the UAE so angry, but they're extremely angry. I also don't know if prisoners have the same rights in the UAE as you would countries like the UK or USA.

June 2nd, McAfee released a paper on malware targeting Minecraft nerds.

Minecraft nerds and malware aside, this is the header image they used in the paper.

New movie coming out about Mark Zuckerberg.

I didn't read the plot because I don't give a fuck, but look at who they hired to play Zuckerberg. It's like if Zuckerberg had a high-functioning autistic Uncle named Mark Uncleberg

I've been asked a bunch about AI and malware.

As many others have stated many times, and I will happily regurgitate, AI acts as an augmentation device to skilled Threat Actors and a kiddy booster to non-skilled Threat Actors.

AI has yet to produce truly sophisticated malware, presumably because non-skilled Threat Actors don't know the correct nomenclature or what exists and what doesn't.

Skilled Threat Actors know what is, and what isn't, possible and AI enhances their skill set and allows RAD (Rapid Application Development) for languages people may be less skilled in.

Conversely, my malware library must adjust appropriately for the future and include malware targeting AI agents. AI focused malware is a new and evolving threat. Is it paramount information like this be archived. Unfortunately, I myself am not an AI expert, I only have an elementary understanding on the programmatic implementation of AI models, hence I am incapable of assessing what is a good malware paper on AI agents, and what isn't.

We'll figure it out.

Cheers

There is some bizarre thought that AI can just wish hyper sophisticated, never seen before, malware into existence. The reality of the matter is that truly sophisticated malware requires quite a bit of creativity combined with objectives and targets. It is not malware aimlessly blasted into the wild.

Someone showed me this on Telegram. It is very silly. It is clearly masquerading as "Free GPT and Claude". Anyone with half a brain knows this is malicious, but people will still fall for it.

People asked what it is. I have some free time. I poked it with a stick,

People discussing it said it is XMRig. That is not entirely accurate. This is not XMRig. This is flagged as XMRig from Triage and VirusTotal because it does indeed drop XMRig, but it is much more than that. This is a (maybe new) information stealer packaged with XMRig as a double whammy.

This malware is interesting because of a few things:

1. It is position independent, they care enough to be evasive and strip out a majority of dependencies. This is usually indicative of more serious malware.

2. They .zip it delivers from the "Free GPT and Claude" is intentionally bloated (payload inflation). It is 97MB, which may evade a majority of anti-malware product (initially) due to it's large size. It packages itself with FFMpeg and various other audio codecs.

3. It accesses Microsoft Outlook e-mails, accesses Chrome stuff using the COM IElevationService, looks for any SFTP credentials

It (currently) does not have any matching YARA rules from AV vendors. The closest approximation is LummaStealer. My knowledge base on the Information Stealer scene is out-of-date (it changes a lot). However, on first initial glance this appears like a new information stealer. Again, this should be taken with a grain of salt.

It's also worth noting the domain it exfiltrates to does not appear in any malware reports. The domain is unique, and the payload does not match any existing YARA rules (it's behavioral characteristics do, but not a specific malware family), so this is actually a pretty interesting sample.

A lookup though shows this is an emerging malware campaign. It first appeared around the end of May. This is (probably) a known Threat Actor who has switched it up a bit (or it's MaaS, whatever though).

The malware appears online masquerading as various products.
- ecore-sourceproject
- LogiDA
- GPT_Claude_Free
- CortexSystems.v3.4.2.Stable
- TikTokBot-v2.2
- CortexLauncher

Funny enough, this malware would have been much, much, much, MUCH more evasive if they didn't package it with XMRig. VirusTotal and Triage immediately flagged it because after it establishes persistence, and steals any credentials on the machine, it pulls XMRig to turn into a cryptocurrency miner.

If they did not pull the XMRig binary this stealer would be much more quiet. I have no idea why they decided to burn their OPSEC with XMRig.
