Space Race: Defenses emerge as satellite-focused cyberattacks ramp up

With cyberattacks becoming a reality against the space sector’s infrastructure in 2022, two groups are aiming to get ahead of future attacks by creating framework initiatives.

The goal of the frameworks is to better understand not only potential threats — in terms of the traditional tactics, techniques, and procedures (TTPs) applied to the space sector — but also to help companies and government agencies create countermeasures against attacks targeting satellites and spacecraft.

On Jan. 3, the US National Institute of Standards and Technology (NIST) and the MITRE Corp., which is also a government contractor, released a version of the NIST Cybersecurity Framework tailored to the ground-based portion of the space sector. The NIST publication complements another effort by nonprofit government contractor The Aerospace Corp., which created in October the Space Attack Research and Tactics Analysis (Sparta) matrix, a version of the MITRE ATT&CK framework applied to threats against space-based infrastructure.

Cyberattacks Are Now Targeting Satellites

Early in 2022, the FBI and CISA warned that attacks against satellite ground-based and space-based infrastructure could become a reality — and it soon did. The year saw nation-state operations targeting Viasat and SpaceX’s Starlink satellites, and forcing governments and aerospace companies to create defenses against the attacks.

In the early days of Russia’s invasion of Ukraine, for example, Russia-aligned hackers targeted the ground-based segment of Viasat’s satellite communications network, taking Internet modems offline throughout Europe. Soon after, Russia also targeted the distributed satellite Internet service Starlink, according to government officials and SpaceX CEO Elon Musk, which has been critical for providing the Ukraine war effort with Internet connectivity.

“Starlink has resisted Russian cyberwar jamming & hacking attempts so far, but [attackers are] ramping up their efforts,” Musk stated on Twitter last May.

In November, Starlink was in the crosshairs again, with Russia-linked Killnet APT targeting it with a DDoS campaign that made the service inaccessible for several hours.

As a corollary, satellites have also become proposed targets of non-cyberattacks as well. In the most recent example, Chinese researchers proposed a 10 megaton nuclear blast 50 miles from the Earth’s surface as a way to disable Starlink satellites that pass through the radioactive cloud.

Computers, Not Lost in Space

Cyberattackers in this arena are far more likely to be advanced persistent threats (APTs) sponsored by nation-states — often looking to disable satellites and spacecraft. But much of today’s ground-based satellite infrastructure uses common computer and communications technologies, which could open the door to other players.

The similarities allow attackers to more easily exploit the systems underpinning satellite systems, while the complex supply chain makes the infrastructure easier to attack, Neil Sherwin-Peddie, head of space security for defense and government contractor BAE Systems Digital Intelligence, stated in a recent column for Dark Reading.
