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 My knowledge base on the Information Stealer scene is out-of-date (it changes a lot).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