Reporting from Washington — Lockheed Martin Corp., the world's largest aerospace company, said Saturday it detected and thwarted "a significant and tenacious attack" on its information systems a week ago.
"As a result of the swift and deliberate actions taken to protect the network and increase IT security, our systems remain secure," said Jennifer Whitlow, a Lockheed spokeswoman. "No customer, program or employee personal data has been compromised."
The Department of Homeland Security and the Defense Department have offered to help gauge the scope of the incident involving the defense contractor.
A person with direct knowledge of the incident said Friday that unknown attackers had broken into sensitive networks of Lockheed Martin and several other U.S. military contractors.
The hackers breached security systems designed to keep out intruders by creating duplicate electronic keys, said the source, who was not authorized to discuss the matter publicly.
The Defense Department said the effect of the Lockheed cyber attack on the Pentagon was "minimal," and it expected no harm to result.
