2025-11-11 (Tuesday): Cryptocurrency #scam starts with an email. Potential victims must click through several web pages to finish the process. I recorded a video showing what I did after the last image in this post at youtu.be/yUV7OkQqSBk

More info on this activity at github.com/PaloAltoNetw...
The scam starts with an email that links to a suspicious web page. I've somehow earned $138,246.83 USD... Let's go down this rabbit hole! Hey, these pages say I already have an account, but I've not been on it for 364 days... Those fools! I'd better click my way through this. Wow, an account I didn't even know I had! I just want my money. Better keep on clicking! A progress bar? What the what??? This made me wait several minutes before I could continue. See the video at https://youtu.be/yUV7OkQqSBk for what happened after.

2025-10-10 (Friday): Was looking for Koi Loader/Koi Stealer, and I found this #WebDAV server that hosted malicious Windows shortcut (#LNK) files.

Malicious Windows shortcut (LNK) files on the WebDAV server. Both are the same file with different names. Traffic from the initial infection filtered in Wireshark. Malware that was persistent on the infected Windows host. Post-infection traffic generated by the peristent malware.

Screenshot of a Facebook post that linked to a page providing the password-protected 7-zip archive for Lumma Stealer. The archive is named "NCH Debut Video Capture Software Pro 11.2 Beta Crack full version.7z" in an attempt to disguise it as a software crack. Extracting a malicious Windows executable file that will install Lumma Stealer from the password-protected 7-zip archive. The extracted file is named "NCH Debut Video Capture Software Pro 11.2 Beta Crack full version.exe" in an attempt to disguise it as a software crack. Traffic from the Lumma Stealer infection after running "NCH Debut Video Capture Software Pro 11.2 Beta Crack full version.exe" on a vulnerable Windows host. Note the unusual DNS query for iUlWkftUnbTjqPSDLGsNPpSG.iUlWkftUnbTjqPSDLGsNPpSG that happened before the HTTPS Lumma Stealer C2 traffic to secrequ[.]top. Files seen from the Lumma Stealer infection in the user's AppData\Local\Temp directory. The .a3x file for Lumma Stealer wasn't on the disk when I conducted forensic analysis on the infected host.
