Hackers launched a "significant and tenacious" cyber attack on Lockheed Martin, a major defense contractor holding highly sensitive information, but its secrets remained safe, the company said Saturday.

Major budget cuts in Pentagon, estimated at $78 billion, won't affect delivery of 20 stealth jets to Israel from 2015 to 2017
Still, the concerted attempt to breach the contractor's systems underscored the risk to the US's critical defense data. Chris Ortman, Homeland Security spokesman, said his agency and the Pentagon were working with the company to determine the breadth of the attack and "provide recommendations to mitigate further risk."
Lockheed Martin said in a statement that it detected the May 21 attack "almost immediately" and took countermeasures. As a result, "our systems remain secure; no customer, program or employee personal data has been compromised."
The company's security team is still working to restore employee access to the targeted network. Neither Lockheed Martin nor the federal agencies revealed specifics of the attack.
