Marine One docs fly to Tehran, but not from Lockheed

A Maryland company appears to have made it possible for sensitive information on Marine One -- President Obama's helicopter -- to turn up at an IP address in Tehran, according to Tiversa, a third-party monitor of peer-to-peer networks. Blueprints, avionics information and cost breakdowns were found on the Iranian computer.

A number of Bethesda-area firms are contractors or subcontractors to the Department of Defense, including Lockheed Martin, which is building the next iteration of Marine One and recently came under fire for spectacular cost overruns on the project. (The current fleet was designed by Connecticut-based Sikorsky.) But a continuing investigation by Rick Earle at Pittsburgh's WPXI says that according to Tiversa, Lockheed is not the source of the leak, which was apparently caused by a contractor who loaded a peer-to-peer client on her or his machine.

Various nations, including several unfriendly to the US, are known to troll the file-sharing networks looking for sensitive information.
