WPXI, NBC's affiliate in Pittsburgh, Tiversa, headquartered in Cranberry Township, Pa., reportedly discovered a security breach that led to the transfer of military information to an Iranian IP address.
The information is said to include planned engineering upgrades, avionic schematics, and computer network information.
The channel quoted the company's CEO, Bob Boback, who said Tiversa found a file containing the entire blueprints and avionics package for Marine One.
"What appears to be a defense contractor in Bethesda, Md., had a file-sharing program on one of their systems that also contained highly sensitive blueprints for Marine One," The Telegraph quoted Boback as telling WPXI.
Tiversa makes products that monitor the sharing of files online. A spokesman for the company was not immediately available for comment.
Boback believes that the files probably were transferred through a peer-to-peer file-sharing network such as LimeWire or Bear Share, and then compromised.
Peer-to-peer file sharing (often called P2P) is a popular way for people to swap digital files on their hard drives over the Internet.
