Darcula Phishing Network Leveraging RCS and iMessage to Evade Detection

Darcula is a Chinese-language phishing-as-a-service platform actively enabling smishing and web-phishing across 100+ countries by providing ~200 templates and over 20,000 spoofed domains hosted across thousands of IPs; it leverages iMessage and RCS to evade network filters, uses cloaking and remote kit updates to resist takedowns, and supports large-scale credential and financial fraud often tied to MFA fatigue and SIM/eSIM swapping techniques.
