The White House said on Tuesday that Brazil-based JBS has informed the U.S. government that a ransomware attack against the company that has disrupted meat production in North America and Australia originated from a criminal organization likely based in Russia.
JBS is the world's largest meat processor and slaughters about 20% of pork and beef in the U.S. The incident caused its Australian operations to shut down on Monday and has stopped livestock slaughter at several of its U.S. plants, including in Worthington.
JBS, however, said late Tuesday that it had made "significant progress" in dealing with the cyberattack and expects the "vast majority" of its plants to be operating on Wednesday.
The ransomware attack follows one last month by a group with ties to Russia on Colonial Pipeline, the largest fuel pipeline in the United States, that crippled fuel delivery for several days in the U.S. Southeast.
White House spokeswoman Karine Jean-Pierre said the United States has contacted Russia's government about the matter and that the FBI is investigating.
"The White House has offered assistance to JBS, and our team at the Department of Agriculture have spoken to their leadership several times in the last day," Jean-Pierre said. "The White House is engaging directly with the Russian government on this matter and delivering the message that responsible states do not harbor ransomware criminals."
The large pork processing plant in Worthington ran its early morning shifts on the kill floor, but ceased work after five hours before canceling Tuesday's night shifts, said Matt Utecht, president of the United Food and Commercial Workers (UFCW) Local 663, representing the plant's workers.
"That basically puts things at a standstill if they're not slaughtering," Utecht said.
