This report analyzes a phishing campaign impersonating Brazilian government sites that leverages generative AI tools (DeepSite AI, BlackBox AI) to create convincing clones. The phishing pages exhibit telltale signs (TailwindCSS, AI-style comments, non-clickable UI), perform staged collection and backend API validation of CPF and personal data, and culminate in victims being instructed to pay a “registration fee” via Pix, indicating active financial fraud.
