About Event

🧠 VIBE25-3: Hack the Prompt – CTF Edition
📅 Friday, August 1 | 6–10 PM
📍 27 South Park St, Suite 100, San Francisco, CA 94107

Dinner and Drinks Provided!!

Three rounds. One goal: break the system before it breaks you.
Join us for a hands-on CTF tackling real-world LLM jailbreak tactics and security flaws. It’s fast. It’s brutal. And it’s wide open.

🧨 The Format:

Round 1: Manual Prompt Attacks
Secure your prompt in 15 minutes. Opponents get 45 to break it—no code allowed.

Round 2: Programmatic Assaults
Write scripts to find the cracks in each other’s LLM defenses.

Round 3: Real-World Exploit
We hand you a Raspberry Pi running an LLM web app—fully exposed to the internet.
Your job: hide the secret. Then hunt everyone else's.
The most broken wins.
