In early January, a new version of the BlackRouter Ransomware was discovered by a security researcher named Petrovic, who shared the sample on Twitter.

Affiliates who join this RaaS and distribute the BlackRouter ransomware will earn 80% of any paid ransom payments, with the other 20% going to the BlackRouter developer.

In addition, this actor is promoting a remote access Trojan called BlackRat that allegedly includes features such as encrypted communications, AV evasion, small size, plugins, the ability to enable RDP, configure a miner, steal cryptocurrency wallets, keylogger, password-stealer, and more.

BlackRouter does not seem to be heavily distributed, with only one submission to ID Ransomware since December 31.

With that said, ransomware like BlackRouter is commonly distributed via hacking into Remote Desktop Services or through fake cracks and downloads. Therefore, make sure to not allow RDP to connect directly to the Internet and be sure to scan anything you download from an untrusted source.
