Article content A ransomware attack that forced the temporary shutdown of the JBS meat-packing plant at Brooks should serve as a wake-up call for the food and agriculture sectors, experts said Tuesday. The Brooks facility, along with JBS’s five biggest beef plants in the U.S., was idled Sunday after a cyberattack on some of the company’s servers, the Brazilian-owned meat processing giant said in a Monday statement. All shifts for unionized workers at Brooks were cancelled until mid-afternoon Tuesday, when production was able to be restarted, according to the union that represents 2,500 employees at the southern Alberta plant.
