We present two widespread design flaws in VPN client. These can be abused to make a victim leak traffic in plaintext outside the protected VPN tunnel.

Tests indicate that every VPN product is vulnerable on at least one device, the researchers say. VPNs for iPhones, iPads, MacBooks, and macOS are extremely likely to be vulnerable, that a majority of VPNs on Windows and Linux are vulnerable, and that Android is the most secure with roughly one-quarter of VPN apps being vulnerable.

Very few people have functional leak checking set up; personally, I think it should be a built-in OS level function.

It would be nice. But it’s a hard problem to solve. To figure out somebody’s intense by running a VPN or having certain IP routing rules.

I do like in this guy day emphasize setting up routing rules so the VPN can only route traffic to VPN endpoints. It’s a nice fail safe
