IEH Corporation, which manufactures connectors used in military satellites, missiles and fighter jets, disclosed a cyberattack to the U.S. Securities and Exchange Commission on Thursday. An employee fell victim to a phishing attack that gave intruders access to an email inbox containing customer communications, purchase orders, engineering documentation and potentially export-controlled technical information, according to an 8-K filing.

The company discovered the breach on Tuesday and said there is no evidence data was taken from the account, though "sensitive information was accessible to the unauthorized party during the compromise period." IEH is taking corrective action to secure the mailbox and preserve evidence. As of Friday, the company said there is no indication the incident will impact its business operations, The Record reports.
