Last week, The New York Times website domain was hacked by "the Syrian Electronic Army". Other famous websites faced the same attack in 2012 by the Hacker group "UGNazi" and, in 2011 by Turkish hackers. Basically, it seems that no Registrar on the Internet is safe from attack, but the launching of new gTLDs can offer new ways to mitigate these attacks.
I am a new gTLD Consultant based in Paris. "New gTLD" stands for "new generic Top-Level Domains" from the ICANN new gTLD program. They are new domain name extensions such as ".consulting" (instead of ".com").
