The Ultimate Guide to Brand Protection with Censys

A Censys-guided operational playbook for detecting and responding to brand-impersonation and phishing campaigns: it covers monitoring Certificate Transparency and precerts, detecting typosquats and brand-prefix domains, searching page content and favicons, pivoting on certificates and banner hashes, tracking historical DNS and host data, clustering related infrastructure, and assembling takedown evidence; the guide uses real examples such as a PowerShell dropper served from an MP4 file, UNC1151 phishing, USPS smishing, and mass lookalike domain clusters to illustrate detection queries and operational workflows.
