A Brief Overview on Satellite Hacking

TO START...


Internet users increasingly rely on satellite to connect to the Web Available almost worldwide •



GPS, TV transmissions, Mapping services etc...



End of 2008, 842,000 US consumers relied on satellite broadband Internet access Satellite types •



Scientific, Earth and Space observation, Reconnaissance, Communications

HOW SATELLITE WORK?


Communications satellites relay transmissions by using the transponder Satellites are usually geosynchronous There are three types of Internet via satellite access: •





One-way multicast


Internet protocols not work correctly because they require a return channel



Unidirectional with terrestrial return (Satmodem) Bidirectional access (Astromodem)

RESEARCH ON HACKING SATELLITES


Typical attacks


Reprogrammed descrambler cards from legitimate equipment to allow unlimited TV service without a subscription hacking into satellite networks to transmit unauthorized material •



Radio enthusiasts can buy all the hardware near any truck stop for less than USD $500



Hacking a Bird in the Sky (September 2006, Geovedi and Iryandi) •

Denial of Service (DoS)

Uplink or Downlink Jamming



Orbital Positioning Transponder spoofing, Direct commanding, Command replay

Satellite Piggyjacking


Selecting target, Pointing antenna, Find “free” frequency, Transmit and Receive, Detection evasion



Hack into satellite transmissions using off-the-shelf components(February 2009 Black Hat DC, Adam Laurie) •
