U.S. authorities have recovered roughly $2.3 million in digital currency that the operators of the Colonial Pipeline had paid to the hackers who conducted a ransomware attack in early May, according to the Justice Department. The company paid 75 bitcoin, roughly $4.4 million at the time, in ransom, and the government recovered 64 bitcoin from a digital wallet belonging to the hackers. Due to fluctuations in the price of cryptocurrency, the dollar value recovered was a little more than half of the dollar value of the ransom payment.
