A data breach may have compromised the personal information of nearly 45,000 Norway Savings Bank customers in Maine.

Norway Savings Bank (NSB) says they suffered a data security incident involving a vendor that may have compromised the personal information of 44,259 people in Maine.

They claim there is no evidence that customer data has been or will be misused, however, there are steps customers can take to help protect themselves.

According to Norway Savings Bank, on August 14, 2025, a security incident occurred at a third-party data services provider of Norway Savings Bank during which an external actor/system obtained unauthorized access to certain portions of the provider’s data environment.

They say the incident did not involve NSB’s internal systems. Upon learning of the incident, NSB says cybersecurity experts were engaged to investigate.

Once the investigation concluded on October 27, 2025, NSB says they began notifying customers of the breach.

According to NSB, the personal information that may have been compromised during the breach are names, addresses, dates of birth, social security numbers, tax identification numbers, and financial account information. Norway Savings Asset Management Group accounts were not affected.

NSB says they are providing free credit monitoring and identity theft protection services through IDX to those affected by the breach.

NSB says they operate a 24-hour fraud monitoring system to examine transactions for fraudulent activity and patterns.

Since learning the breach, NSB says they have also taken several measures to evaluate and rule out patterns of any account misuse or fraudulent transactions.
