Martinelli Winery

The California Office of the Attorney General disclosed a data breach at Martinelli Winery in June 2015, reported by Missing Link Networks, Inc. The incident involved unauthorized access to sensitive customer data over a one-month breach window (April 1–30, 2015). Compromised information included customer names, credit/debit card numbers, payment addresses, passwords, and dates of birth. The exact number of affected individuals remains undisclosed, but the exposure of financial and personal details poses significant risks, including potential identity theft, fraud, and financial losses. The breach highlights vulnerabilities in the winery’s data security measures, particularly in safeguarding payment and personally identifiable information (PII). While no ransomware was mentioned, the scale and nature of the leaked data suggest severe reputational and financial repercussions for both the company and its customers.
