A Russian cyber-criminal group was behind a ransomware attack that has targeted the world’s largest meat processing company, said the FBI.
The FBI said it was working to bring the REvil group to justice for the hack on JBS.
The cyber-breach that happened over the weekend shut some JBS operations in the US, Canada and Australia.
REvil – also known as Sodinokibi – is one of the most prolific and profitable cyber-criminal groups in the world.
“We have attributed the JBS attack to REvil and Sodinokibi and are working diligently to bring the threat actors to justice,” said the FBI statement in a statement.
“We continue to focus our efforts on imposing risk and consequences and holding the responsible cyber actors accountable.”
The White House said on Wednesday that US President Joe Biden would bring up the issue of cyber-attacks when he meets Russian President Vladimir Putin in two weeks.
“Responsible states do not harbour ransomware criminals,” said press secretary Jen Psaki.
JBS said it was on schedule to resume meatpacking operations on Thursday in the US, where its five biggest beef plants are located.
The company, which identified the ransomware attack on Sunday, has not disclosed whether it paid the hackers.
