A Pennsylvania company that monitors peer-to-peer file-sharing networks discovered a potentially serious security breach involving President Obama's helicopter, Marine One, WPXI-TV in Pittsburgh reported.

Sensitive information about Marine One was reportedly found by Tiversa employees at an IP address in Tehran.

Tiversa CEO Bob Boback said a defense contractor in Bethesda, Md., had a file sharing program on one of their systems that contained highly sensitive blueprints for Marine One and financial information about the cost of the helicopter.

"We found a file containing entire blueprints and avionics package for Marine One," Boback said.

Boback said the issue most likely stemmed from someone downloading the file-sharing program without realizing the problems that could result.

"When downloading one of these file-sharing programs, you are effectively allowing others around the world to access your hard drive," Boback told WPXI.

"We found where this information came from. We know exactly what computer it came from. I'm sure that person is embarrassed and may even lose their job, but we know where it came from and we know where it went," Retired Gen. Wesley Clark, an adviser to Tiversa, told WPXI.
