Tri Counties Bank

Tri Counties Bank, also known as TCB, is a financial institution that provides banking services to individuals and businesses. It operates as a bank engaged in accepting deposits and extending credit to support personal and commercial needs. The institution serves customers within its geographic footprint.

The bank maintains more than seventy branch locations, indicating a substantial regional presence. Its headquarters is located in the United States of America, and public descriptions identify it as a California‑based financial institution. This network of branches supports its role as a community‑oriented provider.

Tri Counties Bank has experienced two notable cybersecurity incidents. On March 24, 2023, a ransomware attack led to a network shutdown and an investigation into possible exposure of confidential customer data. On February 1, 2023, the bank suffered a Black Basta ransomware incident that resulted in the publication of identity documents such as passports and driver’s licenses and caused ATM outages, prompting the engagement of third‑party forensic experts.

As a chartered bank, Tri Counties Bank operates under federal and state banking regulations that govern its capital requirements, consumer protection obligations, and operational standards. Its positioning within the financial sector reflects that of a regional bank serving local markets while competing with larger national institutions.
