The advent of internationalised domains has introduced a new threat with the non-english character sets allowing visual mimicry of common domain names. Whilst this phenomenon remains well known in the development and internet industry the actual implementations of popular applications have been previously shown to lack successful mitigation strategies and countermeasures. The research found that in the current versions of most internet browsers and email clients, some form of homograph identification or blocking exists. However, some notable and popular applications include either flawed implementations or miss key features and thus allow for IDN based attacks.
