VPN and DNS exploits

[Code46 1]

Hey all,

 

The recent network solutions hijack got me wondering about VPN connections in such a circumstance. I would assume the DNS exploits would still "work" against a client whose traffic was inside a tunnel because you STILL need to resolve IPs, right? DNS being basically a big trust relationship this seems like a real problem to me.

 

If my question makes sense, can someone explain or point to sources regarding protecting against such exploits if it is possible?

 

Thanks

Hello,

You are wrong in searching for a solution on your side or on VPN side. We mean that maybe you're looking at the problem from an incorrect point of view. The exploit (if we can call it exploit... technically it might be incorrect to name it so) works by obtaining unauthorized access to the DNS authoritative nameservers, or by fraudulent practices by the operators of the nameservers themselves against their own customers!

Thank you for having brought into attention this important topic. We're moving the thread to "General & Suggestions", everyone interested in registering domain names should be aware of the aforementioned practices and should avoid searching for domain names availability from Network Solutions systems.

 

Kind regards
