Norway Savings Bank’s Data Breach Investigation
Norway Savings Bank (NSB), a community-focused financial institution serving Maine residents since 1866, has reported a data breach stemming from a cybersecurity incident involving a third-party data services provider. On August 14, 2025, unauthorized access was detected within the vendor’s data environment, affecting 51,000 individuals — 44,259 of whom reside in Maine.
While NSB’s internal systems were not directly compromised, the breach still involved sensitive NSB customer information. The bank was notified of the incident immediately and remained in close communication with the vendor as they worked with cybersecurity experts to contain the breach and assess the impact.
The investigation, completed on October 27, 2025, confirmed that personally identifiable information (PII) was accessed. This includes names, addresses, dates of birth, Social Security numbers, Tax Identification Numbers (TINs), and financial account details. Fortunately, accounts held under NSB’s Asset Management Group were not affected.
In response, NSB is offering 12 to 24 months of free identity theft protection and credit monitoring through IDX, a leader in breach recovery services. This includes CyberScan monitoring, a $1 million identity theft insurance policy, and fully managed ID recovery services.
Additionally, NSB has maintained ongoing fraud detection and enhanced its internal monitoring protocols. The bank has reassured its customers that no misuse of data has been identified to date, but urges vigilance and proactive security measures.
