The Maine Office of the Attorney General disclosed a data breach affecting Overseas Shipholding Group, Inc. (OSG) on December 2, 2024, stemming from an incident on August 5, 2024. The breach resulted from unauthorized access by an external actor, compromising the personal data of 217 Maine residents. The exposed information included individuals' names and Social Security numbers (SSNs), which are highly sensitive and can lead to identity theft or financial fraud.
