US probes sabotage of satellite internet during Russian invasion

Western intelligence agencies are investigating a cyberattack by unidentified hackers that disrupted broadband satellite internet access in Ukraine coinciding with Russia’s invasion, Reuters reported on Saturday.

Analysts for the US National Security Agency, French government cybersecurity organization ANSSI, and Ukrainian intelligence are assessing whether the remote sabotage of a satellite internet provider’s service was the work of Russian-state backed hackers preparing the battlefield by attempting to sever communications, Reuters reported citing sources.

The digital blitz on the satellite service began on Feb. 24 between 5 a.m. and 9 a.m., just as Russian forces started going in and firing missiles, striking major Ukrainian cities including the capital, Kyiv.

The consequences are still being investigated but satellite modems belonging to tens of thousands of customers in Europe were knocked offline, according to an official of US telecommunications firm Viasat, which owns the affected network.

The hackers disabled modems that communicate with Viasat Inc’s KA-SAT satellite, which supplies internet access to some customers in Europe, including Ukraine. More than two weeks later some remain offline, resellers told Reuters.

Pablo Breuer, a former technologist for US special operations command, or SOCOM, said knocking out satellite internet connectivity could handicap Ukraine’s ability to combat Russian forces.

“Traditional land-based radios only reach so far. If you’re using modern smart systems, smart weapons, trying to do combined arms maneuvers, then you must rely on these satellites,” said Breuer.

Russian soldiers have besieged Ukrainian cities. The invasion has been denounced by the West as an unprovoked assault and it has led to severe sanctions against Moscow as punishment.
