  With more than 294 million registered domain names as of late 2015, the
domain name ecosystem has evolved to become a cornerstone for the operation of
the Internet. Domain names today serve everyone, from individuals for their
online presence to big brands for their business operations. Such ecosystem
that facilitated legitimate business and personal uses has also fostered
"creative" cases of misuse, including phishing, spam, hit and traffic stealing,
online scams, among others. As a first step towards this misuse, the
registration of a legitimately-looking domain is often required. For that,
domain typosquatting provides a great avenue to cybercriminals to conduct their
crimes.
  In this paper, we review the landscape of domain name typosquatting,
highlighting models and advanced techniques for typosquatted domain names
generation, models for their monetization, and the existing literature on
countermeasures. We further highlight potential fruitful directions on
technical countermeasures that are lacking in the literature.
