Phishing Domain Lifecycles

Phishers use a lot of domain names.

Our research shows that most phishing domains are registered by the phishers, often in bulk.

Phishers only have one purpose for these names: point them to fake pages and profit from victims lured there for as long as they can.

Investigators are constantly reporting phishing domains and these are blocklisted or shut down. Ideally, phishing domains have short lifetimes.

Is this conclusion fact or folklore?

Phishing Landscape 2025 Report Released

Phishing Rises to New High of Nearly 2 Million Attacks over 12 Months According to New Interisle Report

Key report findings include:

Phishing attacks rose to 1.96 million a year, a 182% increase since 2021.

Domain Name Abuse Surges to New High: The total number of domain names used in phishing attacks rose 38% to over 1.5 million—the highest ever recorded.

Cybercriminal Domain Purchasing Soars: 77% of all domain names used in phishing attacks were maliciously registered by cybercriminals.

Bulk Registration Enables More Attacks: 37% of all phishing domains were acquired through bulk domain name registration services.

Over half of all phishing sites were hosted by U.S.-based companies. The U.S. has been the top hosting location for phishing for five consecutive years.

The report also examines how domain registration requirements and pricing affect phishing scores in gTLDs and ccTLDs.

Phishing in the 2020s: Bulk Registrations

This post continues the series that looks at aspects of phishing over the past five years.

A previous post examined malicious registration of domain names expressly for the purpose of phishing. In this post, we look at a subset of malicious domain name registratios: those domain names that were registered rapidly and in large numbers - in bulk - by phishers.
