In a post on AllThingsNuclear.org, scientist Laura Grego examines U.S. claims linking the Chinese military to alleged hacking attacks on two Earth observation satellites, and concludes there is very little evidence to back them up.

โ€œWhy would China try to hack a low-resolution earth-monitoring satellite, much of whose data are distributed free and freely, and for which system China even has operated a ground station to assist in collecting data?โ€ she writes.

Grego questions whether the incidents were indeed hacking, and says that even if they were, it is unclear what advantage an unauthorized user could obtain from Landsat-7 and Terra, โ€œwhich are not strategically important or national security-related satellites.โ€

She further notes that no evidence of Chinese involvement is presented in the draft of the U.S.-China Security and Economic Commissionโ€™s annual report to Congress. Greco says the reportโ€™s assertion that the incidents โ€œappear consistent with authoritative Chinese military writingsโ€ is based on one book by a โ€œmarginal figureโ€ in China.
