90% of the top 10 websites, Facebook, Google, Yahoo, Youtube, etc register their Domain Names with a domain registrar called MarkMonitor. If Markmonitor were hacked, the hacker could reset the name servers and effectively make them inaccessible or direct traffic to a phishing website.

  • Is this a potential risk?
  • What security restrictions could Mark Monitor have in place to prevent changes?
  • Is it too costly for these companies to be a registrar themselves (like IBM)

No. You are ignoring DNS propagation times.

What security restrictions could $provider have in place to prevent changes?

The usual to not get hacked. Nothing special here.

Is it too costly for these companies to be a registrar themselves (like IBM)

It is not their core business.
