🔴 Hackers Abuse Stolen BigCommerce App Key to Steal Master of Malt Customer Data

Master of Malt reported a customer data breach after attackers allegedly compromised an application key linked to Ribon, a third-party BigCommerce app managed by Be A Part Of that identifies itself as a Fastr brand.

BigCommerce notified the retailer of the incident on September 18, 2026, prompting Master of Malt to reach out to affected customers within hours.

The company said attackers used the stolen Ribon application credential to access customer information stored in BigCommerce from 17:21 BST on September 13 to 21:12 BST on September 17, when the compromised key was revoked.
