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 My knowledge base on the Information Stealer scene is out-of-date (it changes a lot).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.

@Shitpost_2048 can someone tell me what this is referencing?
the only thing i can think of is that one Quake 3 Arena story where a guy forgot to pause his server for 4 years and when he returned all the bots were completely still but im not sure if thats it

@SockPup93876932 @pickover wouldn't that take... an infinite amount of time? since you *are* processing an infinite amount of digits...
English

@SockPup93876932 @pickover i doubt regex would work for an infinite string...
English

@pickover It’s doable. Have a program calculate Pi and have a regex-check for a sequence of 1 and 0 in mo particular order.

YOU'RE VULNERABLE. YES, YOU. EVEN IF YOU DON'T RUN OLLAMA. You'll get it by the end of this.
throwback to the time when i ratioed ollama for a bug that they still haven't patched to this day
"we take security seriously"
I've had it up to here with companies that think they have good security but never respond to real bugs.
just because it's novel doesn't mean it's invalid. I get that "CSRF" isn't usually used in a DNS-rebinding type scenario where it's browser -> localhost request forgery.
Yes, rebinding is patched but THIS 👏 IS 👏 NOT.
Because *it's not a browser bug* in the first place
it's YOUR bad cybersecurity. YOUR CORS policy leaking all over the bathroom floor.
and i released a PoC, but some of them just dont get it. they don't read the code.
honestly it's your problem atp.
because if i can make a user go onto a website and run the javascript: "fetch('127.0.0.1')", it's not the server that makes the request.
it's the client. and that client sends the information back to the server. it's remote-controlling an ollama server even if it's firewalled and cut off from the internet.
sure, there's password protection, but that was barely around when i published this and it's still not a default.
everything is vulnerable. ive been finding bugs in openclaw, hermes, and every other AI project you could imagine.
they're all so broken.
you can be hacked.
within about 5 minutes of looking through a codebase.
honestly i doubt this tweet will reach many people. i average about 40 per post (lol), but you could help out with a repost.
