Dartmouth College’s Data Breach Investigation

On August 9, 2025, Dartmouth College experienced a security incident due to a vulnerability in Oracle’s eBusiness Suite (EBS) software. This vulnerability, known as a “zero-day” flaw, allowed unauthorized access to data from multiple Oracle EBS customers, including Dartmouth.

Once the breach was detected, Dartmouth acted swiftly to secure their systems and notified law enforcement. An investigation was launched immediately to determine the scope of the breach. After a thorough review, Dartmouth confirmed that between August 9-12, 2025, certain files containing sensitive personal information were accessed and taken by an unauthorized actor.

The breach was discovered on October 30, 2025, after Dartmouth’s investigation revealed that the compromised files included the names, Social Security numbers, and financial account information of 1,494 residents of Maine. To mitigate the potential risks from the breach, Dartmouth has offered one year of free credit monitoring and identity theft protection services to individuals whose Social Security numbers were exposed.

Dartmouth College has also committed to taking further steps to strengthen its data security. This includes implementing all available patches for the Oracle EBS software and continuing to monitor and evaluate the security practices of their third-party vendors.
