PwC Exec: Companies Aren't Aware of Their Vulnerability to Cyber Threats - Via Satellite -
“Intercepting uplink or downlink transmissions that carry Internet Protocol (IP) datagrams or payloads is certainly feasible,” he adds. “Nation states have developed satellites that can park themselves in close proximity of another satellite, and interfere with Telemetry, Tracking, and Command (TTC) uplinks and downlinks. Now, that may not directly equate to a cyber exploit, but if I can insert myself into the uplink or downlink, I can certainly start manipulating the data payloads they carry.”

Satellite data strongly suggests that China, Russia and other authoritarian countries are fudging their GDP reports • The Washington Post
Christopher Ingraham:
<p>China, Russia and other authoritarian countries inflate their official GDP figures by anywhere from 15 to 30% in a given year, according to a new analysis of a quarter-century of satellite data.

The <a href="">working paper, by Luis R. Martinez</a> of the University of Chicago, also found that authoritarian regimes are especially likely to artificially boost their gross domestic product numbers in the years before elections, and that the differences in GDP reporting between authoritarian and non-authoritarian countries can't be explained by structural factors, such as urbanization, composition of the economy or access to electricity.

Martinez's findings are derived from a novel data source: satellite imagery that tracks changes in the level of nighttime lighting within and between countries over time…

"The key question that the paper tries to tackle is whether the checks and balances provided by democracy are able to constrain governments’ desire to manipulate information or, more specifically, their desire to exaggerate how well the economy is doing," Martinez said via email. "The way I try to answer the question above is by comparing GDP (a self-reported indicator, prone to manipulation) and nighttime lights (recorded by satellites from outer space and much harder to manipulate) as measures of economic activity."

Research published in 2012 by economists from Brown University and the National Bureau of Economic Research showed how changes in nighttime lighting closely tracked with changes in economic activity. "Consumption of nearly all goods in the evening requires lights," that paper explained. "As income rises, so does light usage per person, in both consumption activities and many investment activities."</p>

The paper leans a lot on others' data, so it's hard to see quite how reliable this is. One can think of lots of confounding factors. But it's an interesting point.
