FBI Eyes Breach

The FBI is investigating the recent breach of Lockheed Martin's computer networks as a "cyber crime," while the Pentagon is playing a supporting role in analyzing the breach, according to Deputy Assistant Secretary of Defense for Cyber Policy Robert Butler.

"As part of our [Defense Industrial Base] information sharing program, we stand ready to provide assistance, with [the Department of Homeland Security]," Butler told a forum in Washington Thursday. However, "on all cyber crime activity [the FBI] has the mantle," he said.

"The analysis on these activities, first of all is challenging," Butler said. "It's diffuse and has lots of different pieces that have got to be put together." Lockheed Martin said last week that it suffered a computer network attack on May 21. A Defense Department spokeswoman said the "impact to DOD was minimal" and that the department "did not expect any adverse effect" as a result of the breach.
