Python RAT with a Nice Screensharing Feature, (Tue, Nov 5th)
While hunting, I found another interesting Python RAT in the wild. This is not brand new because the script was released two years ago[1]. The script I found is based on the same tool and still has a low VT score: 3/64 (SHA256:1281b7184278f2a4814b245b48256da32a6348b317b83c440008849a16682ccb)[2].

Scans for RDP Gateways, (Wed, Oct 30th)
RDP is one of the most prominent entry points into networks. Ransomware actors have taken down many large networks after initially entering via RDP. Credentials for RDP access are often traded by “initial access brokers”. I noticed today an uptick in scans for “/RDWeb/Pages/en-US/login.aspx” . This is often used to expose RDP gateways, and there…
