Bangalore: The communications satellites that are suspended in orbit above the earth were often considered to be safe and away from danger. But, a survey report by the US-China Economic and Security Review Commission alleges that hackers have hampered with two military satellites, reports Information Age.

The report which was released towards the end of previous year claims that in the year 2008, hackers supposed to be working from China hindered with two US government satellites- Landsat-7 and Terra AM-1.The former satellite was under  the control of hackers for a time span of 12 minutes and the later one was held for two minutes.

Paul Marsh, satellite communications enthusiast explained his doubts on the report while speaking at the London Security B-Sides event in April.

“First off,” he explained, “jamming a satellite is easy to trace. Every time a command is sent up to the satellite, it gets counted. If you send one wrong frame up to then a red light will start flashing at RAF Oakingham.”

He also did some calculations to get an idea about the energy that might be required to attack a Skynet satellite. The power transmitted will be about five million watts, which is as much power as a train produces and according to Marsh, the fact whether the hackers had the finance to send tracking and telemetry date to the Skynet satellite still remains  a matter of disbelief.
