Ransomware group
blackout
Blackout surfaced in February 2024 and operates using a double-extortion model. Targets span sectors like healthcare, mining, telecommunications, and food & beverage—in countries including France, Canada, Mexico, Croatia, and Spain. This ransomware employs conventional cryptographic techniques (details unspecified), appends a custom extension to encrypted files, and presents victims with ransom demands via a Tor-based leak/negotiation site. The operation runs as a crypto-ransomware and data broker, combining extortion with data publication threats.
