Federal officials have recovered millions of dollars in Bitcoin(BTC, -0.83%)that Colonial Pipeline paid to a criminal outfit during a ransomware attack, CNN reported Monday.
Colonial Pipeline paid about $4.4 million in bitcoin to the attackers, linked to the Darkside ransomware group, after its payment systems were frozen last month. The company had to halt fuel transportation across the East Coast of the U.S., sparking fears of a gas shortage in a dozen states.
Ransomware attacks have been on the rise recently, with a number of high-profile and critical infrastructure firms falling victim to the cyberattack.
The U.S. Department of Justice did not immediately share further details.
