Colonial Pipeline Co. paid nearly $5 million to Eastern European hackers on Friday, contradicting reports earlier this week that the company had no intention of paying an extortion fee to help restore the country’s largest fuel pipeline, according to two people familiar with the transaction. The company paid the hefty ransom in untraceable cryptocurrency within hours after the attack, underscoring the immense pressure faced by the Georgia-based operator to get gasoline and jet fuel flowing again to major cities along the Eastern Seaboard, those people said. Once they received the payment, the hackers provided the operator with a decrypting tool to restore its disabled computer network. The tool was so slow that the company continued using its own backups to help restore the system, one of the people familiar with the company’s efforts said.
