Virtual private networking (VPN) companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a target’s traffic off of the protection provided by their VPN without triggering any alerts to the user.
I couldn’t quickly find an answer to this, but would setting the “UseRoutes” option in systemd-networkd to false prevent the dhcp client from using the option 121 routes?
If so, would this be a possible mitigation for linux devices using systemd?
