Description
Diamond Foods, LLC detected suspicious activity within its IT environment on January 23, 2021, prompting an immediate investigation with assistance from third-party forensic specialists. The investigation revealed unauthorized access to Diamond Foods' network between January 19 and January 23, 2021. Additionally, forensic analysis uncovered a separate compromise of one employee email account that had been accessed without authorization from December 8, 2020, to January 8, 2021. The company conducted a comprehensive review of potentially exposed data, which concluded on May 6, 2021, to identify the types of sensitive information involved and the individuals affected. This review determined that the incident potentially impacted personal information including names, dates of birth, Social Security numbers, driver's license numbers, financial account numbers, and health insurance information. Diamond Foods subsequently undertook an internal records review to obtain accurate mailing addresses for notification purposes. While the company found no evidence that personal information was actually viewed or misused by unauthorized actors, it proceeded with notifications as a precautionary measure.
Upon discovering the incident, Diamond Foods implemented immediate containment measures by securing its network infrastructure and the compromised employee email account. The company maintained that its investigation found no indication of attempted or actual misuse of the exposed data. Impacted individuals received guidance to monitor account statements and credit reports for suspicious activity, though Diamond Foods did not report any concrete instances of identity theft or fraud linked to the breach. The organization emphasized its commitment to information security through prompt incident response actions, including forensic analysis, system remediation, and stakeholder notification. Public disclosure occurred nearly six months after detection through a July 15, 2021 press release and website notice, with the delay attributed to the time required for forensic review and address verification. The incident exposed multiple categories of sensitive personal data but resulted in no confirmed downstream harm beyond the initial unauthorized network and email access.
