Community Bank Reports Data Exposure Involving Employee Use of Unauthorized AI Application

Community Bank disclosed a cybersecurity incident that exposed customers’ names, dates of birth, and Social Security numbers after an employee used an unauthorized artificial intelligence-based software application. U.S. Securities and Exchange Commission dated May 7, 2026.

It is evaluating the customer data that was affected and is sending notifications in accordance with relevant laws.

TechCrunch reported that Community Bank did not disclose how many customers were affected by the incident, nor what AI application was involved. The bank operates in Pennsylvania, Ohio, and West Virginia. John Montgomery is chief executive of Community Bank.
