Colonial Pipeline CEO Joseph Blount confirmed that he authorized a $4.4-million ransom payment to hackers in order to get the critical energy artery operating. The company paid about 75 bitcoin in exchange for decryption software, the Wall Street Journal reported. “I didn’t make it lightly,” Blount said. “I will admit that I wasn’t comfortable seeing money go out the door to people like this.” The ransomware infection at Colonial highlighted the vulnerability of critical infrastructure. The FBI blamed the attack on a group called Darkside, which is believed to be based in Russia.
