Posted on October 18, 2021 by Dissent

Technical Details

Overview

First seen in July 2021, BlackMatter is ransomware-as-a-service (Raas) tool that allows  the ransomware’s developers to profit from cybercriminal affiliates (i.e., BlackMatter actors) who deploy it against victims. BlackMatter is a possible rebrand of DarkSide, a RaaS which was active from September 2020 through May 2021. BlackMatter actors have attacked numerous U.S.-based organizations and have demanded ransom payments ranging from $80,000 to $15,000,000 in Bitcoin and Monero.
