WWHF @ Mile High 2025

Vishing—using phone calls as an attack vector—remains an effective and often underestimated form of social engineering. In this hands-on workshop, Jason Downey, a Penetration Tester for Red Siege, will walk you through how attackers conduct reconnaissance, build convincing pre-texts, and execute successful vishing scenarios. With its low risk and high reward, vishing is a technique both penetration testers and defenders need to understand. This workshop isn’t just for red teamers—defenders will gain valuable insights into processes and strategies that can help prevent and detect vishing attacks. The session concludes with an interactive AI-powered Vishing CTF, where you’ll have the chance to practice and refine your skills in a fun, realistic environment.
