US meatpacking plants get back on stream after crippling cyber-attack

Experts warn no one is out of bounds' after ransomware attack halts production at JBS, which supplies more than fifth of US beef

Meat-processing factories in the US run by the world's largest company in that field are coming back on stream on Wednesday after a ransomware attack - as experts warned all corporate and local government leaders to be on the alert.

A cyber-attack on the meat processor JBS had forced it to halt all US operations while it scrambled to restore functionality. The attack, like other recent hacks, is believed to have originated in Russia.
