From there, the attackers had been capable of concurrently ship the disabling command to modems throughout Europe, rendering them ineffective however not completely unusable, Viasat stated.

It was not recognized how the attackers breached the VPN equipment. Satellite cybersecurity researcher Ruben Santamarta stated it was essential to know whether or not they had obtained credentials or exploited a recognized vulnerability. Viasat declined to supply specifics Wednesday, citing an ongoing investigation.

Gregory Falco, a Johns Hopkins University professor specializing in satellite tv for pc system safety, stated the influence on affected programs was minor in comparison with what the attackers had been able to doing.

Falco stated it’s probably they’ve maintained a foothold. “The attackers don’t want to show their whole hand or any of their positioning for how they plan to persist in the network,” he stated.

The hacked ground-based community is run by Skylogic, an Italy-based subsidiary of Eutelsat, from which Viasat bought the KA-SAT satellite tv for pc in April of final yr.

Viasat’s investigation of the assault was completed by the U.S. cybersecurity agency Mandiant.
