WASHINGTON: The American subsidiary of the world’s largest meat processing companies said Monday it had been hacked, paralyzing some of its operations and impacting thousands of workers in Australia.

The intrusion was detected Sunday, forcing one of the leading producers of beef and pork in the United States to suspend affected systems, and call in its IT staff and third-party experts to deal with the breach.

“JBS USA determined that it was the target of an organized cybersecurity attack, affecting some of the servers supporting its North American and Australian IT systems,” the unit said in a statement.

The hack comes less than a month after a major cyberattack shut down the Colonial Pipeline network, which transports about 45 percent of fuel consumed on the east coast of the United States.

Brazil-based JBS is a sprawling meat supplier with operations in the United States, Australia, Canada, Europe, Mexico, New Zealand and Britain.

The company’s Australian facilities were said to have been paralyzed by the attack, with up to 10,000 meat workers being sent home without pay, according to a union representative.
