On May 31, 2021, JBS, a major Brazilian meat processing company, was hit by a ransomware attack that had a significant impact on its operations across North America and Australia. The incident prompted the company to shut down several systems to contain the breach. Fortunately, JBS reported that its backup servers remained unaffected, allowing it to work on restoring services promptly. While the company confirmed that customer, supplier, and employee data appeared to be secure, the attack highlights the ongoing threat posed by ransomware to critical infrastructure and food supply chains.
