Target 11 broke this story on Saturday.

Marine One Security Breach

A Navy spokesman told Target 11 investigator Rick Earle that the Navy knew Iran had the helicopter information last summer.

TiversaCEO Bob Boback said just last week one of his employees discovered engineering and communication documents about the Marine 1 fleet had been downloaded to an IP address in Iran.

Boback said he immediately alerted the federal government.

The Navy told Target 11 on Monday it was investigating a possible breach involving Marine One.

On Tuesday, it said it knew about the incident last summer.

A Navy spokesman said an internal review in June determined the documents posed no significant impact to the presidential helicopter program.

But they said the information should not have been made available on the Internet or in the public domain.

They also turned over all of the information to the Navy's criminal investigative service.

In June, Tiversa said it warned the federal government that an IP address in Iran was searching for information.

A few months later, Tiversa said they discovered the helicopter documents while searching file-sharing programs, but at that time they hadn’t been downloaded to Iran.

Then last week, Tiversa discovered those same documents had been downloaded to the IP address in Iran.

Tiversa traced the original documents back to a defense contractor.

Boback said someone from the company most likely downloaded a file-sharing program, typically used to exchange music, not realizing the potential problems.

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

WPXI also learned exclusively Monday that Lockheed Martin was not the source of the sensitive information disclosed about Marine One. Speculation has been circulating on the Internet that the defense contractor that inadvertently disclosed the information was Lockheed Martin.

Boback founder of Tiversa, said the information did not come from Lockheed Martin.

He would not name the contactor that was that was the source, but told Target 11 definitively, "It is not Lockheed."

Tiversa also found sensitive financial information about the cost of the helicopter on that same computer.

"We found where this information came from," said Retired Gen. Wesley Clark, an adviser to Tiversa. "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."

Boback notified the government immediately and said appropriate steps are being taken.

“They are working through a process to maintain the security of the president,” Boback said.

Monday afternoon, President Barack Obama’s press secretary responded to Target 11’s exclusive investigation.

“I would point you to the Department of the Navy. They have more information, but I think some of the reports are not as they seem,” Robert Gibbs said.

Iran is not the only country that appears to be accessing this type of information through file-sharing programs.

“We've noticed it out of Pakistan, Yemen, Qatar and China. They are actively searching for information that is disclosed in this fashion because it is a great source of intelligence,” Boback said.

Clark said he doesn't know how sensitive this information is, but he said other military information has been found on the Internet in the past.

He said this needs to be monitored more closely and Rep. Jason Altmire agreed. He said, "Well, I'm very troubled to hear this because there are obviously elements in Iran that are not friendly to the United States and it would be an understatement to say that this type of information could be very detrimental were it to fall into the wrong hands."

Altmire said he will ask Congress to investigate how to prevent this from happening again.

Clark said, “Once it's out there, it's hard to get it back. I don't think the full ramifications of this have been understood by the watchdog agencies.”

Tiversa was founded in 2004 by Robert Boback and Sam Hopkins, both Pittsburgh natives.

Boback is a Norwin High School graduate and got his college degree from the University of Pittsburgh.

Co-founder Hopkins is a Peabody High graduate and started Nauticom and went on to work for Fiore Systems and the Marconi Company.
