California County Says Personal Information Compromised in Data Breach


The incident, Tehama County says, was identified on April 9, but the investigation into the matter stretched to August 19, when it was determined that personally identifiable information (PII) was compromised.

The investigation revealed that an unauthorized third-party had access to the county’s systems between November 18, 2021, and April 9, 2022, and that files on the county’s department of social services systems were accessed.

“The County of Tehama determined that information pertaining to certain current and former County of Tehama employees, recipients of services from the County of Tehama Department of Social Services, and other affiliated individuals was contained in one or more of those files,” the county says.
