Hiding in Plain Sight: A Longitudinal Study of Combosquatting Abuse
Domain squatting is a common adversarial practice where attackers register
domain names that are purposefully similar to popular domains. In this work, we
study a specific type of domain squatting called "combosquatting," in which
attackers register domains that combine a popular trademark with one or more
phrases (e.g., betterfacebook[.]com, youtube-live[.]com). We perform the first
large-scale, empirical study of combosquatting by analyzing more than 468
billion DNS records---collected from passive and active DNS data sources over
almost six years. We find that almost 60% of abusive combosquatting domains
live for more than 1,000 days, and even worse, we observe increased activity
associated with combosquatting year over year. Moreover, we show that
combosquatting is used to perform a spectrum of different types of abuse
including phishing, social engineering, affiliate abuse, trademark abuse, and
even advanced persistent threats. Our results suggest that combosquatting is a
real problem that requires increased scrutiny by the security community.Comment: ACM CCS 1
