We'll share a new date and time soon, so keep an eye out - thanks for your patience and understanding! 🙏

The year is about to end 🎆 So let's have a look which networks are hosting most active malware distribution sites 👀

Actually, it doesn't surprise that the networks leading the ranking, proton66 and ELITETEAM, are bulletproof hosters who refuse to react on abuse reports sent by URLhaus ✉️ Both get upstream connectivity from Russian network operators 🇷🇺

If you want to do yourself something good, drop 🛑connections from/to these network at your perimeter!

The malspam contains a PDF with a link to a fake AnyConnect installer. Once downloaded and executed, the payload will open Cisco AnyConnect on the Microsoft App Store to mask the BumbleBee infection🔥

The BumbleBee payload comes with a DGA of 300 .live domains. Active #botnet C2s ⤵️
