A major US fuel pipeline has reportedly paid cyber-criminal gang DarkSide nearly $5m (£3.6m) in ransom, following a cyber-attack.
Colonial Pipeline suffered a ransomware cyber-attack over the weekend and took its service down for five days, causing supplies to tighten across the US.
CNN, the New York Times, Bloomberg and the Wall Street Journal all reported a ransom was paid, citing sources.
Colonial said on Thursday that it would not comment on the issue.
On Friday, Japanese consumer tech giant Toshiba said its European division in France had been hit by the same cyber-criminal gang.
