For your comfort and peace of mind, check with traceroute (tracert in Windows) or mtr, and/or access various end points which tell you the IP address your packets come from. Typical speed tests sites and "what is my address" web services are perfect. Compare the IP address you get with the supposed exit-IP address of the VPN server you're connected to and verify they match. Finally, query the IANA database (with whois) for a final cross-check. Repeat multiple times for each server to minimize the likelihood that you end up to services which are accomplices of the attackers and therefore mask your IP address making you believe that you have a perfectly fine IP address while in reality your packet has come out from inside the evil Russian network.
As a welcome and smart side-effect, while the attackers could do nothing with the data in transit inside their nodes because of end-to-end encryption, a re-routing of such a kind which would add an additional exit node would turn infringement notices against us exactly to zero, and alas this is not what we observe, not at all 🙄. We have never met such kind and gentle attackers, unfortunately.
Kind regards 😋
