Captured a screenshot of a live #panel of the #Ermac 3.0 #Android #bot builder. Some interesting functionality here: ✅ #C2 connection URL ✅ Backend encryption key ✅ Crypt the #apk ✅ Emulator blocking ✅ Custom icon ✅ Build with a clean app #malware

Interesting interview with the author of #Amadey loader, which is consistently one of the top malware families observed in the wild recently
A few days ago, #Amadey owner and I did a brief interview. We talk about past, present and future of the infamous #Amadey Loader, one of the biggest products in the MaaS environment. Something worth a read. Please find it at: g0njxa.medium.com/approachin…

Interesting shift for #Vidar C2 servers: some communications occur on the port 11111 (why?) Malware builds still use profiles on Telegram and Steam as Dead Drop Resolver. Recent C2: 116.203.2.]149:11111 116.203.220.]83:11111 95.217.246.]227 116.203.240.]51 116.203.15.]24

Interesting change in #Vidar infostealer C2 traffic. Instead as part of the multipart payload, the Id, Token and hwid are now sent as part of the header. Sample: tria.ge/230222-yxyhdsfb6z/be…

I've had a few people ask me recently where is a good place to get started with #MISP threat information sharing platform. If you are looking for a very detailed intro to MISP, I highly recommend this video series from @FIRSTdotOrg: youtube.com/watch?v=-NuODyh1… #threatintelligence
