In late December 2025, Senior Aerospace Jet Products and Ketema, formerly a division of Senior Operations LLC (“Senior”), detected and responded to an attempted ransomware attack impacting its systems. Initial analysis suggested that the attack was successfully blocked by existing security controls. However, further forensic review completed in late February 2026 confirmed that an unauthorized actor accessed files containing sensitive personal information.
Senior immediately launched a full investigation with the assistance of external cybersecurity professionals, implemented containment procedures, and began strengthening its internal security controls. Impacted individuals are now being notified.
Senior Operations LLC is part of Senior plc, a global engineering group that designs and manufactures high‑technology components and systems for aerospace, defense, and industrial applications. Its divisions include Senior Aerospace Jet Products and Ketema, which supply critical components to the aviation industry and maintain facilities across the United States.
As part of its response efforts, Senior engaged cybersecurity experts, implemented additional safeguards, and is offering complimentary identity protection and/or credit monitoring services for one year. Impacted current and former employees must contact Senior’s Director of Benefits & HRIS by May 15, 2026 to activate their services.
