After days of outages, NCR Corp. has confirmed that its Aloha point-of-sale (PoS) software platform, used by thousands of restaurants across the US, was taken down by a ransomware attack on one of its data centers.

The BlackCat ransomware group has claimed responsibility for the Aloha POS cyberattack.

“Please rest assured that we have a clear path to recovery and we are executing against it,” NCR’s disclosure said. “We are working around the clock to restore full service for our customers.”
