ATHR is a commercialized TOAD (telephone-oriented attack delivery) platform sold on underground markets that automates the full vishing attack chain—spoofed notification emails, AI-driven voice/social-engineering agents, browser-based WebRTC telephony, and live credential/2FA harvesting—enabling single operators to run large, adaptive campaigns that can bypass standard email authentication and static detection rules, thereby increasing the scale and effectiveness of phone-phishing attacks.
