Officials say there is no evidence that flight control systems were compromised

The U.S. military makes heavy use of UAVs in many areas of the world for reconnaissance duties. The UAV is widely used in Iraq and Afghanistan as well as in Somalia and other locations. The drones are used to track and sometimes attack targets when needed.

The Wall Street Journal reports that enemy insurgents have been able to use a commonly available piece of software to intercept the unencrypted feeds that the drone uses between the aircraft and ground control. The software used by the insurgents to capture the video feeds was a $26 app available online called Sky Grabber.

One of the developers of the Sky Grabber software told the WSJ in an email, "It [Sky Grabber] was developed to intercept music, photos, video, programs and other content that other users download from the internet -- no military data or other commercial data, only free legal content."

The military claims that there is no indication that he insurgents were able to take control of the drones or interfere with their flight in any way. However, some fear that the ability to capture the live video feeds will allow the insurgents to track the position of the drones to better avoid attack and surveillance. The big fear is that intercepted feeds could be used to discover allied troop surprise attacks and lead to the death of allied soldiers.

The interception of the video feeds from the aircraft was apparently not a onetime occurrence. In the summer of 2009, the WSJ reports that the military found "days and days and hours and hours of proof" that the video feeds were being intercepted on a laptop that was recovered from a Shiite militant.

A defense official James Clapper was asked to assess the interception of the feeds and concluded, "There did appear to be vulnerability. There's been no harm done to troops or missions compromised as a result of it, but there's an issue that we can take care of and we're doing so."

The military is working on encrypting all feeds from its drone aircraft, but adding encryption to the feeds requires not only updates be added to the drones, but updates to the control systems on the ground as well. The U.S. first learned of the flaw in unencrypted drone feeds in Bosnia during the 1990s, but the Pentagon assumed that the insurgents wouldn't know how to exploit the vulnerability.

While the evidence of feeds found was most prolific in Iraq, there is evidence that the feeds have been intercepted in Afghanistan as well. "There was evidence this was not a one-time deal," said a person close to the matter.

Fixing the security gap in the drones during the program development would have added delays according to former security officials and would have added to the cost of the drones. Even the new generation of drones called Reaper have feeds that are unencrypted.

It's unclear whether the successor to the Reaper called the Avenger will suffer from the same issue with unencrypted security feeds.

Truely disappointing.

Wow, to think that they would be so short sighted to think that because they are insurgents they wouldn't figure out how to tap into an unencrypted feed. These insurgents have millions of dollars to buy weapons and computers and other devices to to help fight their war.

What if their was a real conflict with another power? They surely would be tapping into all feeds and try to unencrypted some of the other feeds as well maybe try to take control of our drones. And surely they'd view any and all unencrypted feeds.

I am quite surprised the people designing these things are that retarded. It is not hard to add encryption to some damn feeds. It can be done in software and by the sound of it even weak 128bit encryption would stop this from happening.
