A denial-of-services (DoS) attack on a major satellite comms company on the working day of Russia’s invasion hit tens of 1000’s of prospects in Ukraine and in other places, the firm has exposed.
Viasat said the “multifaceted and deliberate” cyber-attack took the majority of its hundreds of Ukrainian prospects offline, while the network was “largely stabilized in hours” and entirely stabilized in several days.
It commenced when some hijacked modems and other customer products inside Ukraine began firing superior volumes of focused malicious targeted visitors, producing it hard for genuine modems to continue being on the web.
Even though defenders labored to force the malicious modems offline, others joined the network to keep on the attack more than the next many several hours, Viasat stated.
“Subsequent investigation and forensic examination discovered a floor-dependent network intrusion by an attacker exploiting a misconfiguration in a VPN equipment to get remote access to the trustworthy management segment of the KA-SAT network,” the provider stated.
“The attacker moved laterally by means of this dependable management network to a precise network section applied to handle and function the network, and then used this network obtain to execute legitimate, focused administration instructions on a huge number of household modems concurrently. Exclusively, these harmful instructions overwrote important data in flash memory on the modems, rendering the modems unable to accessibility the network, but not forever unusable.”
Viasat claimed the influenced modems could be fully restored by way of a manufacturing unit reset and that it has no proof that firmware was compromised. Having said that, the organization has been pressured to reissue just about 30,000 modems to distributors to carry customers again on the internet.
There is also no evidence to counsel that the firm’s KA-SAT satellite or supporting floor infrastructure was compromised in the attack.
