🚩 CTF 10 — The Agentic Edition 🚩

The game has changed. For years you hacked web apps, reversed binaries, and cracked crypto. But the adversary evolved. Today the threat isn't just code sitting still — it's an agent. Autonomous AI systems now run their own recon, write their own exploits, and make their own decisions in real time.

So this year, we're settling it: vs. .
You don't just hack systems anymore. You hack the agents themselves.

Your mission in 10:
🤖 Break the agent's guardrails and bend it to your will
💥 Force remote code ex*****on out of an AI that was built to refuse you
📂 Trick it into leaking the data it's supposed to protect
🧠 Outsmart a machine that's trying to outsmart you

This is the frontier of offensive security — and you get to attack it first.

The reward? Finalists win a plane ticket to , for the live grand finals this October — an on-site showdown in one of the most beautiful cities in Mexico.
You don't need to be an expert. You need to be curious, stubborn, and ready to learn fast. Every champion we've crowned started exactly where you are right now.

🎓 Grab your team. Pick your name. Make it legendary.
⚡ Qualifiers: August 14–16 — fully online.

The agents are ready. Are you?

🚨 2017. was tearing through the world, and Mexico ranked number 1 in LATAM for corporate impact.

That same period, one night, DanuX picked up the phone and started cold-calling universities across Mexico with a bold idea: build the country's first-ever nationwide hacking competition. One rule — you had to be an active college student in Mexico. 🇲🇽

Nine editions later, the numbers speak for themselves:

a) 2,000+ students have competed
b) Many are now the cybersecurity engineers, team leaders, and managers defending Mexico's top companies today
c) New CTF competitions have emerged for students: HackMex, PwnTillDawn, HiTB Mexico and every local security conference has a CTF tournament

We've watched talent rise from every corner of the country:
🔹 Zacatecas — quietly producing some of the sharpest minds in the game
🔹 IPN & UNAM — always a guarantee of elite engineering talent
🔹 Puebla — BUAP and ITESM bringing serious firepower
🔹 Monterrey — ITESM and UANL going head-to-head like college football rivals
🔹 From Sonora and Chihuahua, down through Veracruz, all the way to Yucatán and Campeche

This wasn't just a competition. It became a pipeline for a generation of defenders.

And now? We're celebrating our 10th anniversary — and stepping into a new era: 🤖

Welcome to the Agentic Era. Welcome to HackDef

To kick off the celebration, enjoy the official HackDef 10 soundtrack 🎶 — written by Ramses Vazquez, with sound and voice produced using AI.

IDA is strong where it matters:

Debugger
Decompiler
Control

Everything you need to actually understand the code.

Most people ask:
IDA or Ghidra?

But real analysts don’t think that way.

One gives you precision.
The other gives you speed.

The difference isn’t the tool…
it’s how you use them.

At Hack Defender Academy, we train you to master both—because that’s what real-world analysis demands.

Are you the best? Prove it.

Every defender starts somewhere — for Cherifi Houdaifa, it started with CTFs.

Coming from BSides Algiers Shellmates Club, Cherifi took the next step and challenged himself with the CCWD – Certified Crimeware Defender program.

Through hands-on challenges and real-world scenarios, he strengthened his skills in malware reverse engineering and built the mindset needed to face modern threats.

This is what happens when passion meets the right opportunity.

Communities like BSides and CTF platforms continue to prove they are essential in shaping the future of cybersecurity.

We’re proud to be part of that journey.

Understanding shellcode isn’t about writing code.

It’s about understanding how systems actually execute.

Most people stay at the surface.

A few go deeper.
That’s where the difference is.

The stack is one of the most important memory structures in low-level programming.

Every time a program runs a function, stores parameters, or returns ex*****on, the stack is working behind the scenes managing that data.

Understanding how PUSH, POP, and stack frames work is essential for reverse engineering, vulnerability research, and malware analysis.

Many exploitation techniques and malware behaviors rely on manipulating the stack to redirect ex*****on flow.

If you want to understand how programs really execute at the lowest level, you need to understand the stack.

Learn these concepts and many more in Hack Defender Academy.

Malware doesn’t just execute. It checks its environment.

If it detects monitoring tools running inside the same host, it may stop communicating completely.

That’s why network-level simulation matters.

𝙄𝙉𝙚𝙩𝙎𝙞𝙢 allows you to simulate real internet services inside your isolated lab — DNS, HTTP, HTTPS, SMTP, FTP — without intercepting traffic locally inside the malware’s system.

Fewer red flags.
More visibility.
Deeper behavioral analysis.

And yes — we teach how to use INetSim properly inside 𝙈𝙤𝙙𝙪𝙡𝙚 2: 𝙏𝙤𝙤𝙡𝙨 𝘼𝙧𝙨𝙚𝙣𝙖𝙡 at Hack Defender Academy.

Because understanding the difference between host-level interception and network-level simulation changes how you analyze malware.
