The world’s largest meat processing company has been targeted by a sophisticated cyber-attack.
Computer networks at JBS were hacked, causing some operations in Australia, Canada and the US to temporarily shut down, affecting thousands of workers.
The company believes the ransomware attack originated from a criminal group likely based in Russia, the White House said.
It follows a similar attack last month on the largest fuel pipeline in the US.
In a ransomware attack, hackers get into a computer network and threaten to cause disruption or delete files unless a ransom is paid.
The White House says the FBI is investigating the attack.
