What the JBS cyberattack means for meat supply Some shoppers may want to brace themselves for yet another possible supply crunch — this time with meat. Major beef and pork producer JBS USA suffered a cyberattack last weekend, prompting reported shutdowns at company plants in North America and Australia. The White House has said that the ransomware attack was likely carried out by a Russia-based criminal organization, and that it is dealing with the Russian government on the matter. The Australian government has said that US law enforcement is taking the lead on investigating the attack. So far, some authorities and trade groups have assured that operations will be back to normal as soon as possible, allaying concerns of major disruption. But experts warn that it will depend on how quickly the issue is taken care of.
