The other one that happened was just before Russia invaded Ukraine, they managed to disable the Viasat modems. And this is an interesting case. These modems are used for satellite communications. And they were able to attack these modems so that they physically disabled themselves. It was not like the denial of service attack on the network. No, they managed to wipe the firmware of all these modems in such a way that it could not be replaced. The reason we know about this stuff so well is it turns out there were lots of windmills that also had these modems. In Germany, apparently 4,000 of these modems stopped working. And there were 4,000 wind turbines that could no longer be operated. So this was a military cyber attack that happened as Russia was invading Ukraine. And it was of great benefit to them because it disabled a lot of military communications in Ukraine. But this is the kind of thing that can happen, only that it’s quite rare.
Russia compromised Viasat modems before the Feb2022 invasion, to disrupt Ukraine's satcoms for the military. However these modems are also used in German windparks, losing control over 4000 windmills.
