A new ransomware operation called BlackMatter, which attacks corporate companies and buys network access for further attacks, was recently discovered to be a renamed version of DarkSide ransomware gang by encryption algorithms.

Following a careful investigation of the nature of the new ransomware group BlackMatter, BleepingComputer revealed after cross-examination by Emisosft CTO and ransomware expert Fabian Wosar a decryptor of a BlackMatter victim.

It was found that the new group uses the same unique encryption methods that DarkSide uses to carry out its attacks.

BleepingComputer knows of several victims targeted by BlackMatter with ransom demands ranging from $3 million to $4 million.

DarkSide was responsible for the major Colonial Pipeline attack that occurred earlier this year.
