The Russian hacking group DarkSide, which was behind the cyberattack that shut down the Colonial Pipeline, collected more than $90 million in bitcoin ransom payments from 47 victims, blockchain analytics firm Elliptic said in a report released Tuesday. "To our knowledge, this analysis includes all payments made to DarkSide, however further transactions may yet be uncovered, and the figures here should be considered a lower bound," said Tom Robinson, Elliptic's co-founder and chief scientist. The average payment to get DarkSide to undo the effects of its malware was about $1.9 million. The hacking operation was on track to have its most lucrative month ever when it lost access to its servers and abruptly closed after the attack on Colonial forced the company to shut down a pipeline that supplies about 45 percent of the East Coast's gasoline. Colonial reportedly paid DarkSide about $5 million in ransom.
