A ransomware attack on Blue Yonder, a leading supply chain software provider, has caused significant disruption to operations at several major US and UK retailers. The attack, which was first reported by CNN, has affected the company's managed services hosted environment, resulting in widespread outages and disruptions to its 3,000 corporate customers.

In a statement on its website, Blue Yonder confirmed that it had experienced disruptions to its services, which were determined to be the result of a ransomware incident. The company said it has been working diligently to recover from the incident, but as of Sunday, it did not have a timeline for restoration.

The impact of the attack has been felt across the retail industry, with several major US and UK retailers confirming that they have been affected. Morrisons, one of the UK's largest supermarkets, said that the outage at Blue Yonder had affected its warehouse management systems for fresh and produce. The company is currently operating on its backup systems and is working to deliver for its customers across the country.

Sainsbury's, another major UK supermarket chain, also confirmed that its operations were hit by the attack. However, in a later statement, the company said that its services had since been restored. In the US, Starbucks confirmed that the ransomware attack had disrupted the organization's ability to pay baristas and manage their schedules, forcing managers to manually calculate employees' pay.

Not all of Blue Yonder's customers have been affected by the attack. Tesco, the largest supermarket chain in the UK, and DHL Supply Chain, a division of German-based logistics giant DHL, both confirmed that they were unaffected by the ransomware incident.

The ransomware attack has not yet been claimed by any major ransomware group, and it is not yet known if any customer data was stolen. Blue Yonder's investigation and restoration efforts remain ongoing, and the company has not provided any further information on the attack or its impact on its customers.

The attack highlights the vulnerability of supply chain software providers to cyber threats and the potential for widespread disruption to critical business operations. As the investigation continues, it remains to be seen what measures Blue Yonder will take to prevent similar attacks in the future and what steps its customers will take to mitigate the impact of the disruption.

The incident also raises concerns about the security of supply chain software providers and the potential for cyber attacks to disrupt critical infrastructure. As the use of technology continues to grow in the supply chain industry, it is essential that companies take proactive measures to protect themselves against cyber threats and ensure the continuity of their operations.

In the meantime, Blue Yonder's customers are left to deal with the consequences of the attack, including disruptions to their operations and potential losses to their business. The incident serves as a reminder of the importance of robust cybersecurity measures and the need for companies to be prepared for the unexpected.
