About Merck
Merck is a major multinational pharmaceutical company based in Rahway, New Jersey. The company focuses on developing and producing medicines, vaccines and animal health products.
What Happened?
In September 2025, Merck Sharpe & Dohme learned of a data breach involving one of its U.S.-based service providers, Graebel Companies Inc., which handles employee relocation management services.
The breach occurred when Graebel detected unauthorized access to its systems and promptly took steps to contain the incident and assess its impact.
After reviewing the affected files, Graebel notified Merck on Sept. 22, 2025, that the data of some current and former Merck employees was involved. Merck completed its own review by Oct. 20, 2025, confirming that certain individuals’ information had been impacted.
The breach was reported to the Massachusetts Attorney General’s office on Nov. 17, 2025. The full extent of the breach is not yet known, but it could be significant. The company is mailing notices to affected individuals.
