🎉 Five years ago today (16 Oct 2020), I played my first-ever CTF solo - unknowingly starting something much bigger.

What began as one person’s challenge became @hackasec , Nepal’s #1 cybersecurity CTF team and a global contender.

That's a wrap on Pwn2Own Berlin 2026! 🏆 $1,298,250 awarded. 47 unique 0-days. 3 days of absolute chaos. And talk about main character energy - congrats to DEVCORE for claiming Master of Pwn with 50.5 points and $505,000 - they never slowed down. See you next year! #Pwn2Own #P2OBerlin

Mind blown alert 🤯! Nguyen Hoang Thach (@hi_im_d4rkn3ss) of STARLabs SG (@starlabs_sg) used a Memory Corruption bug to exploit VMware ESXi with the Cross-tenant Code Execution add-on, earning a sweeeeeet $200,000 and 20 Master of Pwn points. Full win let's go! #Pwn2Own #P2OBerlin

It's changing very fast, it's been more than 5 years doing and don't want to completly stop doing. I still try to stay in game limiting myself to just one good CTF a month will see how this goes, and hoping to see different format and more onesite game 🥲

I started playing CTFs in 2022, and LLMs definitely changed the **competitive** CTF scene a lot, especially since mid-2025. I also started using LLMs in late 2025. Yes, those models did one-shot many challenges, but what's the fun of slopping them? I learned absolutely nothing 🥲

[Kabir Acharya @Kabir4charya]

I've been seeing posts all over about the state of CTFs post-LLM. I've seen many attempts to explain why this is just a new evolution of CTFs, but I fundamentally disagree. I believe the original spirit is gone and I've written why in my blog.

That's my chain — a full chain w/ logic bugs only! No memory corruption, no AI, and of course no collisions at all 😉

This should change the opinion of the last person who doubted AI
