Using domains for fraud has been a serious problem for years. Bad actors use various tactics to deceive users and steal sensitive data like passwords and credit card details, yet until now no widely adopted solution existed to stop them at the source.
To tackle this, a team of Princeton University students developed Predator, a software tool that proactively detects and blocks fraudulent domains at the point of registration, before they’re ever used for spam or phishing. According to its creators, Predator catches 70% of attempted fraudulent registrations with a false positive rate below 0.5%.
In the paper published by the Predator team, the core hypothesis is straightforward: bad actors register large quantities of domains at the lowest possible price. This keeps their campaigns running even as individual domains get flagged or taken down.
A few months ago, in our article “Cheap Domains That Cost You Dearly,” we noted that domain price was emerging as a potential trust signal. Paying $3 more for a domain is barely noticeable to a regular user. But for fraudsters operating at scale, it’s a massive cost increase, enough to make many of their schemes economically unviable.
