Hackers Targeted US Satellites

Getty/George Doyle/Thinkstock(WASHINGTON) -- On at least two occasions, hackers have taken over U.S. satellites and targeted their command-and-control systems, a report by the U.S.-China Economic and Security Review Commission revealed Wednesday.

The incidents involved two Earth observation satellites. While it may be difficult to trace who hacked the satellites, U.S. officials acknowledged the incidents had to come from a nation power.

U.S. officials cannot clearly trace the incidents to China, but the report released by the congressionally mandated commission noted that Chinese military writings made reference to attacks on ground-based space communications facilities.

“Chinese military writings advocate attacks on space-to-ground communications links and ground-based satellite control facilities in the event of a conflict. Such facilities may be vulnerable,” the report noted, “In recent years, two U.S. government satellites have experienced interference apparently consistent with the cyber exploitation of their control facility.”

The report noted that some of the malicious cyber activity targeting the satellites involved NASA’s Terra EOS satellite being targeted in June 2008 and again in October 2008. The June incident resulted in the satellite being interfered with for two minutes and the October incident lasted at least nine minutes.

The report noted that in both instances, “The responsible party achieved all steps required to command the satellite but did not issue commands.”

The report noted that the Landsat-7 satellite operated by the U.S. Geological Survey experienced similar interference and events in 2007 and 2008 but added that the entity behind that incident did not achieve the ability to control the satellite.

The report mentions the serious implications the intrusions could have on the satellite systems, particularly if they were directed against more sensitive systems such as military or communications satellites.
