💥 Call for Failures @ hack.lu 2025 — Because We All Break Things

At hack.lu, we love stories of brilliance — new tools, cutting-edge exploits, and clever defenses.
But let’s be honest: the best lessons often come from things that went spectacularly wrong.

That’s why we’re bringing back the Call for Failures (CFF) — a mini-conference inside hack.lu dedicated entirely to sharing the things that didn’t go as planned.

🗓️ When: Wednesday, 22 October 2025
🕖 Time: 19:00 – 21:00
📍 Where: At hack.lu, Luxembourg

What is the Call for Failures?

CFF is your chance to take the stage for 10 minutes and talk about a failure — yours or someone else’s — that taught you something meaningful in cybersecurity.
No buzzwords, no corporate slides, no blame games — just honest stories, good humor, and lessons learned.

Maybe you:

  • Deployed a “quick” fix that took down your entire network.
  • Spent months building a tool that no one used.
  • Misconfigured a system in a way that taught you more than any training ever could.
  • Tried to improve security… and made it worse.

If it broke, crashed, backfired, or blew up (figuratively, please), we want to hear about it.

Why share your failure?

Because every broken system, every bad idea, and every facepalm moment makes our community stronger.
At hack.lu, we believe in learning by doing — and sometimes by failing spectacularly.
Your story could help someone else avoid the same mistake, or maybe even inspire a better way forward.

Format

  • 10-minute talk (short, raw, and real)
  • No slides required — but they’re welcome
  • Can be technical, organizational, or personal
  • Anonymous submissions are possible (we know how it is…)

Submit your story

Head to 👉 https://2025.hack.lu/cff/

Submissions are open — we’re looking for honest, funny, painful, and insightful talks from across the security spectrum or related.

Remember: failure isn’t the opposite of success — it’s the path that leads to it.
So come share yours. Let’s laugh, cringe, and learn together at hack.lu 2025.
