Lockheed Martin Faces Alleged Data Breach by APT-Iran Hacktivists

Lockheed Martin has been targeted by the hacktivist group APT-Iran, which claims to have exfiltrated 375 gigabytes of sensitive data, including technical documentation related to the F-35 fighter jet and internal communications. The group has threatened to sell this data for over $400 million to adversaries of the U.S. The attack was reported on March 20, 2026, via APT-Iran's Telegram channel, although the claims remain unverified as no evidence has been published. Lockheed Martin has stated that it is aware of the claims and has measures in place to mitigate cyber threats. The group has a history of targeting critical infrastructure, including a recent phishing attack on a Jordanian company. APT-Iran has also warned users of Starlink devices about potential tracking by Israeli intelligence. The situation is still developing, with no confirmed breach at this time.

Key Points: • APT-Iran claims to have stolen 375 gigabytes of data from Lockheed Martin. • The group threatens to sell the data for over $400 million to U.S. adversaries. • Lockheed Martin has confirmed awareness of the claims and maintains confidence in its security.
