Willie Zhang is an Offensive Security Consultant with experience protecting companies by thinking like an attacker. What started as a $1 online course on ethical hacking in college turned into a career built on finding the gaps in systems that aren't supposed to have any. Willie has a growing passion for understanding and attacking AI systems, building on a foundation of testing everything from corporate networks to the humans that run them. When he's not learning something new, Willie is in a League of Legends lobby, because apparently cybersecurity isn't chaotic enough.
Session
What happens when you social engineer an AI agent that was trained to be helpful over the phone? Can you get it to reveal its system prompt out loud? Will it disclose information about other callers? How far can you push it before its guardrails kick in?
Voice AI agents are the same LLMs we've been prompt injecting, just with a phone number instead of a chatbot. Yapper is the open-source tool I built to test them.
