Following the discovery, the company confirmed that 22,822 individuals were affected and began issuing written notifications to those impacted.

The incident is classified as medium severity due to the successful penetration of company systems by an unauthorized third party.

Impact and risks for Barnhart customers

The breach at Barnhart impacts more than 22,000 individuals, many of whom may now face heightened security risks. Although the specific data categories were not disclosed, breaches involving external hacking often target names, contact information, or other sensitive identifiers. Affected individuals may be at risk for targeted phishing campaigns, where attackers leverage the context of the breach to gain further access to personal accounts. There is also a potential risk of identity theft or credential harvesting if login details were stored within the compromised environment.

To mitigate these risks, individuals should monitor their financial accounts and credit reports for any suspicious activity. Implementing multi-factor authentication (MFA) across all personal and professional accounts is a vital protective step. Maintaining transparency and following the company’s guidance can help minimize the long-term impact of the exposure.

• Monitor credit and financial statements. Regularly check bank and credit card statements for any unauthorized transactions. Consider placing a fraud alert or security freeze on your credit reports with major bureaus.
