After the vulnerability was detected, the bank hired cybersecurity specialists to look into the issue, and the team determined that personal documents could have been stolen. CNBF sent a notice to the Maine Attorney General's Office on June 30, 2023.

Who Does the Breach Impact?

Approximately 36,300 bank customers were affected by this data breach. Each of those customers could have had some or all of the personal data points listed above exposed to the attackers.
