A ransomware attack on supply chain vendor Blue Yonder has impacted Starbucks in the U.S. and supermarkets in the U.K. — Here’s what we know so far.

Starbucks said Monday that a ransomware attack on a third-party software provider is hindering its ability to track baristas' hours and manage their pay.

According to CNN, Blue Yonder solutions are also used by US grocery chains, including Albertsons and Kroger, as well as other types of companies such as Ford, Procter & Gamble, and Anheuser-Busch, but it’s unclear if they have been impacted in any way.
