The California Office of the Attorney General reported that Far Niente experienced a data breach on April 24, 2023, involving unauthorized access to email accounts and internal documents. The breach potentially affected personal information including names, credit card numbers, and addresses but the exact number of individuals affected is unknown. The breach was reported on September 11, 2023.

On August 21, 2017, Far Niente Winery suffered a data breach involving unauthorized access to its computer network. During the incident, files were encrypted, raising concerns about the potential exposure of sensitive personal information, including names, addresses, and Social Security numbers. However, the California Office of the Attorney General’s report clarified that there was no evidence to suggest the unauthorized individual viewed, copied, or misused any of the compromised data. While the breach involved encryption—often associated with ransomware tactics—the lack of confirmed data exfiltration or malicious use mitigated the immediate harm. The incident primarily highlighted vulnerabilities in the company’s network security, though the actual impact on affected individuals remained speculative rather than confirmed.
