New Typosquatting Classifier
Typosquatting is a form of URL hijacking that relies on typographical errors (typos) made by users while entering a URL into their web browser. This results in the user being directed to an alternative website owned by an attacker. The typosquatting URL is visually similar to the legitimate URL, such as:
The typosquatting URL usually directs to online scams, such as advertising pages used to generate profit from ads or phishing pages used to steal information from users.
The new classifier aims to protect users from typosquatting domains targeting most popular domains. The classifier effectively identifies the domains similar to the most popular domains by calculating the similarity of domains. The classifier then determines the severity of the threat based on additional parameters, such as the age of the typosquatting domain.
