Tri Counties Bank Data Breach Investigation
The Lyon Firm is actively involved in class action personal privacy and data theft cases and is currently investigating Tri Counties Bank data breach claims for plaintiffs in California and nationwide.
What Happened at Tri Counties Bank?
Tri Counties Bank detected a ransomware incident affecting its systems in February 2023 and only started to alert consumers by letter in October 2023. Many details are still unknown, though the company admitted that an unauthorized party allegedly released sensitive personal information belonging to the bank’s customers. Tri Counties Bank posted a notice of the data breach on its website.
The company stated, “Through our investigation, we determined that our internal bank network had been infected with malware which prevented access to certain files on the network.”
Reports suggest that over 74,000 individuals may have had their data compromised by the hack, including name, Social Security number, driver’s license number, state identification number, financial account information, medical information, health insurance information, date of birth, passport number, digital/electronic signature, tax identification number, access credentials, and mother’s maiden name.
Why did it take so long for Tri Counties to alert individuals of the attack? In fairness, the company did post notice of an outage that was investigated. But the investigation did not conclude anything definitive until months later, in which time sensitive data of tens of thousands of individuals may have been available on dark web forums for cybercriminals to manipulate. Leaked Social Security numbers in conjunction with medical and financial accounts info can be devastating in terms of the level of fraud and identity theft potential.
