According to the changelog for 2024.2:

Security

  • Fix DNS leaks in blocking states or when no valid DNS has been configured due to an underlying OS issue. In these cases a dummy DNS will be set to prevent leaks.

I have tested with the current version and it appears to leak exactly like it did before. So any time a person is on an unreliable connection, it is likely to leak their DNS requests.

Procedure:

Always On VPN enabled.

Block connections with VPN enabled.

  1. Connect to VPN server.
  2. Verify at Mullvad website than VPN is connected and no DNS leaks.
  3. Go to ipleak website and verify no DNS leaks. Leave page open.
  4. Disconnect VPN
  5. Return to ipleak website open page and see that testing has paused due to disconnected.
  6. Reconnect VPN
  7. Return again to ipleak website open page and it will show 4 connections made to your local/ISPs DNS server.
