Think Tank Report Warns Of Cyberterrorism In Space
Space is cold, crowded, and vulnerable to hackers. At least, that’s the heart of “Space, the Final Frontier For Cybersecurity?,”
a new report from London-based think tank Chatham House. People on
Earth depend on satellites for everything from GPS driving directions to
phone and internet access, to mapping the world itself. Satellites are,
at heart, computers with fancy bodies that communicate to Earth, so it
stands to reason that they share some similar pathways for malicious
attacks
The problem is in two parts: one, that lots of systems in space were designed before cybersecurity was really a thing, and two, hackers are unpredictable threats, especially when compared to nations. “Hackers ... currently constitute a major problem; their culture is entirely different from that of government or the military,” write the study’s authors.
So how can hackers get into satellites? Most likely through benign neglect. More satellites mean more entry points; more parts inside a satellite means a vulnerability could be installed from the start; more devices connected to satellites mean more ways in; and the demand for and cost of fast production leave ways for security to be left out of the manufacturing and set-up process. One predicted vulnerability stands out, and that’s “back-door holes in encryption and otherwise secure control systems.” While it’s impossible to prevent hackers from finding these, countries that mandate back-doors around encryption open up their satellites for attackers.
For nations
to protect against this threat, the study argues, they’re going to have
to work together and take cybersecurity seriously. That means a light
regulatory regime on every part of the space supply chain, and a lot of
fiddly bits of negotiating between countries and companies about
managing the risk.
Perhaps the greatest risk, even with a system in place to mitigate the threat, is that the people senior enough to make the important decisions won’t grasp the technology as well as their younger employees or hacker adversaries.
As the authors write, “younger people use space-based and cyber communications in ways that make it difficult for older generations – and thus by implication some senior decision-makers – to fully understand the range of technologies and threats.”

Once
hackers get into satellite systems, what’s the worst they could do?
Lots of mucking about with communication signals, for sure, but the real
danger comes from collisions. Satellites have engines to adjust their
course in orbit, usually to make sure they’re where they're supposed to
be. But, the authors write,
Any satellite that can change orbit can be considered a space weapon. If the orbit changes so as to enter the pathway of another satellite then a collision will ensue, destroying one or both of the satellites and creating space debris that will continue to pose severe risks for other satellites far into the future. In addition, the more satellites there are, the greater the possibility of collision with debris, leading to a cascade effect known as the Kessler Effect, mentioned above, as the spatial density of debris increases[.]
The
study authors note that that hackers could potentially take over a
satellite, prove they could move it, and then ransom that satellite or
others, relinquishing control after payment is made.
What if the hackers were less interested in extortion and more interested in destruction? The study addresses the dreaded space terrorism, too:
What if the hackers were less interested in extortion and more interested in destruction? The study addresses the dreaded space terrorism, too:
Terrorist groups wishing to promote their causes, even up to the catastrophic level of satellite collisions with space debris including a cascade of collisions ... [deny] the use of space for all actors.
