How do phishing kits deploy lookalike domains at scale?

Phishing kits include domain generation and rotation capabilities. Attackers rapidly register many lookalike domains, deploy identical phishing content across all, and rotate to fresh domains as others are blocked.

Scale economics: cheap domain registration, automated deployment tools, and template-based content enable mass lookalike operations. A single campaign might use hundreds of domains over its lifetime.

Defense challenge: blocking individual domains can't keep pace with generation speed. Content-based detection (recognizing phishing page patterns) and URL reputation (identifying infrastructure patterns) provide more durable protection.
