I already wrote about the increasing problem of IDN homograph attacks and made a parallel with .BRAND new gTLDs; but this is a "must watch" interview with ICANN’s Andrew McConachie, Security and Stability Advisory Committee (SSAC) Chair and Rod Rasmussen discussing the use of Internationalized Domain Name (IDN) homographic attacks.
This problem is not a new one, but the number of these attacks...is increasing with new gTLDs. Banks and other sensitive businesses can considerably reduce the risk of these attacks when operating their own domain name extension: not because they will be able to better control the Top-Level Domain, but just because they will be able to control who registers domain names.
