The Department of Homeland Security and Department of Defense has offered help in determining the extent of the incident, performing analysis of available data in order to provide recommendations to mitigate further risk.
Lieutenant Colonel April Cunningham said that hacking on Lockheed Martin's network won't affect the army as the situation is under control.
Lockheed Martin, manufacturer of sophisticated weapons and fighter jets like F-35 Joint Strike Fighter and the F-22 Raptor, came under cyber attack on May 21. Company officials claimed that they had identified the attack immediately and prevented the loss of data.
Responding to the attack, Lockheed employees were asked to change their "SecurID" passwords and to reset all passwords used throughout the entire company. Lockheed also disabled remote access to security systems.
