IEH Corporation, a manufacturer of specialized military equipment, has reported a cyber incident involving unauthorized access to an employee's email inbox. The breach was disclosed in a regulatory filing with the U.S. Securities and Exchange Commission (SEC) after the company discovered the intrusion on Tuesday. The attackers gained access through a phishing attack, which compromised emails containing sensitive information such as customer communications, purchase orders, and potentially export-controlled technical data. Although there is no current evidence that data was exfiltrated, the information was accessible to the unauthorized party during the breach.
Efforts are underway to secure the compromised mailbox and preserve any evidence for ongoing investigations. As of the latest update, the company assured that its business operations remain unaffected by this incident. IEH Corporation, known for its connectors used in critical military systems like satellites, fighter jets, and missile programs, is taking corrective actions to address the situation. The company's products are integral to various defense programs including THAAD and Patriot missiles, as well as fighter jets utilized by European nations and India. Despite the breach, IEH's reported revenue for the 2026 fiscal year was close to $30 million.
Requests for additional comments from IEH Corporation went unanswered at this time.
