The Future is Calling
In the Social Engineering Community’s Battle of the Bots: Vishing Edition, teams will design AI-powered agents to place live vishing (voice phishing) calls in a soundproof booth, attempting to extract pre-defined objectives from real human targets. This competition pushes the boundaries of hacking, automation, and human psychology to explore just how far artificial intelligence can go in mimicking the art of social engineering.

Want to Compete?
If you or your team are bold enough to create an AI agent that can think fast, talk smart, and vish better than a human, we invite you to apply for this groundbreaking competition.
This is your shot to show off the current state of Social Engineering AI.
Applications close June 30, 2025 @ 5 PM PT, and accepted teams will be announced on July 2, 2025.
How the Competition Works
Please read carefully – this isn’t your average CTF.
Teams: You may compete solo or with a second person (a duo). Each team will be responsible for developing and deploying an AI-driven voice agent capable of performing vishing calls without any live human intervention during the calls themselves.
The Call: During live calls, only your AI agent may speak. No team member may talk on the call, though you may assist your bot’s operations—like monitoring, triggering fallback behaviors, or prompting follow-ups—without generating live voice. All team members must enter the booth to manage your bot’s deployment and interface and may communicate with each other silently or via notes.
Application Video: To apply, submit your application as well as a video (max 2 minutes) explaining why you or your team should be selected. This is your chance to show your creativity, details about your bot and your experience with AI, technical vision, and goals.
If You're Accepted
Company & Objectives Assignment: Each team will receive a target company and a list of objectives (with point values) that your AI bot must attempt to extract during its vishing calls.
Competitor Webinar: We will host a private competitor-only webinar for those accepted to discuss the competition and answer any questions after the teams have been selected.
OSINT: Unlike our SECVC, OSINT will be your responsibility and will not be graded for points. We still highly recommend it.
AI Bot Development: Prior to your live call at the village, this will be your time to develop and fine-tune your AI vishing agent, including its voice model, NLP capabilities, call logic, safety controls, etc. You, and your bot, MUST also abide by our the DEF CON Code of Conduct and the SEC Code of Ethics. You are welcome to use third-party tools, services, APIs for your bot, but you and your team will be fully responsible for those and the SEC will not reimburse any costs.
Direct contact with your target is forbidden: That includes phone calls, emails, or any active probing. When in doubt, consult SEC staff.
Bot Vishing Plan: Alongside bot development, you must submit a Bot Vishing Plan Report detailing:
- The AI agent’s pretext(s) and logic flow
- Phone numbers your bot will call AND the source of where you found that phone number
- Technical summary of your AI agent stack and showing how you’re following our Code of Ethics
- And More
A template and example will be provided. Submissions will be judged and scored, and feedback will be available on request.
The Hardware: You and your team will be responsible for the hardware and software your bot will run on. The SEC will provide you with two things during the call:
- USB A or C port: A USB A or USB C Dante AVIO audio adapter. This will provide a virtual speaker and microphone which our AV team will use collect the sound from your bot.
- Softphone credentials: You will be responsible for connecting to our PBX to place the calls. We recommend using Bria Soft Phone. You are responsible for getting your bot to be able to communicate over the softphone.
- Network Access: While in the booth, you will be provided with a hardline Ethernet cable to the internet. This will work, unless the DEF CON network goes down :).
Required Surveys: All team members must complete a brief pre-competition and post-competition survey to support SEC’s research. These take less than 15 minutes each.
Live at DEF CON: At DEF CON in the Social Engineering Community Village, each team will have a scheduled time to run their AI agent live. Your bot will place real-time vishing calls to reach your assigned objectives. Judges will score based on performance, objectives captured, and creativity – plus limited style points for standout approaches.
