The most obvious is former Soviet republics, or any neighbour of a target nation, being mis-identified. That includes Ukraine itself, by the way, but also Finland and Poland. How about territory that is disputed? Or adjacent to enclaves like Kaliningrad? But it can also include friendly-nation assets that just happen to be currently inside Russia or Belarus, including government entities and journalists. It can affect folks simply relying on mobile networks near borders. Address blocks are routinely reallocated, reassigned, reused, misused, on a global basis and an address range announced in Korea last year can show up in Canada tomorrow.
Even geolocation by client-side request can be wrong, too. Not just because it's easy to lie, but major nations also fuck with the GPS, which is an issue currently affecting Baltic aviation¹. By the same token, IP geolocation databases are easily misled by self-reporting from mobile devices. Simple example: imagine someone using a dedicated VPS in the US as a personal VPN exit node for their devices when visiting mainland China (actually, we don't have to imagine: I did exactly this). Any IP-based location assumptions start out incorrect, since it's by VPN exit IP; but later on, thanks to mobile device reporting, that IP address can end up misclassified long-term as "Chinese".
None of this is hypothetical. I visited Jordan a few years ago and whilst visiting ruins near Umm Qais, up by the Sea of Galilee, my phone was switching to Israeli networks. I also know of an Australian startup that was mis-identified as Russian and lost access to a major partner API². That's since resolved, but the point is, forget what you see on police procedurals; identifying the political jurisdiction of a device, whether it's by IP address or any other means, remains an art, not a science, and it's incredibly easy to be wrong.
As for the suggestion that the rest of us remain unaffected; any malware incident in the node ecosystem requires immediate attention and audit from every security team, whether you were the intended target or not. This idiot has cost all of us time and energy.
