Sounds like the attack bypasses the VPN entirely. It’s not a worry on your home network if you control the DHCP server. But, on public networks, where you really should always use a VPN, you can’t be sure your traffic is going through the VPN.
Maybe, you can check a trusted site like the VPN provider’s webpage to see if you’re going through the VPN. But, a really sophisticated attack could potentially route just that traffic through the VPN and everything else outside of it.

If my reading of it is correct.
