Stockman Bank

Stockman Bank is a financial institution headquartered in the United States. On May 30, 2023, the bank experienced a data breach that originated from a third-party incident. This unauthorized access resulted in the acquisition of personal information for over 5,000 individuals. The compromised data specifically included names combined with Social Security numbers. The financial institution discovered the breach and subsequently offered affected persons a one-year subscription to credit monitoring and identity theft protection services. These services were provided by Kroll, a firm that specializes in such protective measures. The incident was documented in a public report from the state of Maine, which details the scope and nature of the security event. The breach underscores the vulnerability that can arise from dependencies on external vendors within the financial sector. The bank's immediate response focused on mitigating potential harm to impacted individuals through the provision of identity theft protection. This event represents a significant security incident for the institution involving sensitive consumer data.

The breach was not contained within the bank's own systems but stemmed from a compromise at a third-party provider. This external origin points to risks in the supply chain of data handling for financial entities. The specific data type exposed, names linked with Social Security numbers, is particularly sensitive and highly valuable for identity theft. The bank's remedial action was limited to offering a one-year service from Kroll, a standard industry response to such incidents. The public disclosure through a state regulatory filing confirms the bank's legal obligation to report the breach. No additional details about the bank's operational scale, specific services, ownership structure, or other distinguishing attributes are provided in the available information. The profile of Stockman Bank, based solely on the documented incident, is that of a U.S. financial institution that suffered a third-party data breach affecting thousands with high-risk personal information and responded with a standard credit monitoring offer.
