Lockheed Martin is investigating claims of a massive data breach by the pro-Iran hacktivist group APT Iran.
The group alleges the theft of 375 terabytes of sensitive company data. This cache reportedly includes blueprints for the F-35 fighter jet.
The hackers posted threats on Telegram demanding over $400 million to prevent the sale of data to U.S. adversaries.
A Lockheed Martin spokesperson confirmed the company is aware of the reports. The firm maintains procedures to mitigate cyber threats. Multiple security researchers are currently reviewing the claims.
