👥 Community We’re Gathering

This is an underground-style community meetup — the event where you’ll meet your friends, because we’ll make sure to bring them in.

• Red teamers sharing stories of initial access and persistence
• Vulnerability researchers dropping bugs and tooling
• Bug bounty hunters revealing what slips past prod
• Blue teamers showing detections that actually worked

🎯 Tracks

Offense
Pentesting, red teaming, exploit development, vuln research, bughunting.

Defense
SOC, DFIR, detection engineering, threat hunting, blue team ops — field stories, not theory.

🧩 Talk Format

• Up to 40 minutes total
• Including Q&A

🧾 Guidelines for Submissions

• Write a strong abstract. Avoid generic descriptions or AI-generated topics. We need to clearly understand what you’ll present.
• Less talk, more shell. Bring something that actually runs.
• Talks and slides must be in English (live translation available for everyone).
• All talks may be recorded on video. Consent will be requested during application.
