TL;DR
Community Bank in Pennsylvania, Ohio, and West Virginia revealed a security lapse after customer data was potentially shared with an unauthorized AI application. The bank is investigating the scope of the breach and notifying affected customers.
Community Bank has disclosed a cybersecurity breach after customer data, including names, dates of birth, and Social Security numbers, was potentially shared with an unauthorized AI application, raising concerns about data security and privacy.
The bank, which operates in Pennsylvania, Ohio, and West Virginia, filed an 8-K report with the U.S. Securities and Exchange Commission on May 7, 2026, revealing that it detected an exposure of sensitive customer information due to the use of an “unauthorized artificial intelligence-based software application.” The bank did not specify the number of customers affected or identify the AI application involved but stated it is evaluating the scope of the data breach and is sending notifications in accordance with legal requirements.
According to the filing, it appears that an employee or representative may have uploaded customer data to an online AI chatbot or similar platform without authorization, which could have exposed this information to the AI provider or third parties. Community Bank’s CEO, John Montgomery, has not responded to requests for comment, and the bank is still assessing the full extent of the incident.
