A ransomware attack on Blue Yonder over the weekend is affecting Starbucks' ability to track employee hours on Monday.

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.

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.
