US: Computer hackers, possibly from the Chinese military, interfered with two US government satellites four times in 2007 and 2008 through a ground station in Norway, according to a congressional commission.
The intrusions on the satellites, used for earth climate and terrain observation, underscore the potential danger posed by hackers, according to excerpts from the final draft of the annual report by the US-China Economic and Security Review Commission. The report is scheduled to be released next month.
“Such interference poses numerous potential threats, particularly if achieved against satellites with more sensitive functions,” according to the draft. “Access to a satellite‘s controls could allow an attacker to damage or destroy the satellite. An attacker could also deny or degrade as well as forge or otherwise manipulate the satellite’s transmission.”
A Landsat-7 earth observation satellite system experienced 12 or more minutes of interference in October 2007 and July 2008, according to the report.
Hackers interfered with a Terra AM-1 earth observation satellite twice, for two minutes in June 2008 and nine minutes in October that year, the draft says, citing a closed-door US Air Force briefing.
