01 // Briefing

One last run.

As 2026 approaches its final moments, 0xV01D presents a special year-end edition of our international CTF series.

Following two successful editions, we are bringing the global cybersecurity community together one last time in 2026 for 48 hours of hacking, problem-solving, and intense competition — a farewell to the year, and one final run.

From advanced binary exploitation to cryptographic mysteries, reverse engineering, web exploitation, and digital forensics, participants will face a diverse collection of original challenges designed to test their creativity, technical expertise, and determination.

Whether you are an experienced CTF player, a cybersecurity researcher, a student, or an aspiring ethical hacker, THE FINAL EXPLOIT is your opportunity to end 2026 with one final cybersecurity challenge.

Our mission is to bring together cybersecurity talent from around the world, encourage technical learning, promote ethical hacking, and provide a competitive environment where participants can demonstrate their skills. We believe cybersecurity grows stronger through collaboration, education, creativity, and continuous technical challenges.

02 // Disciplines

Seven ways in.

Challenges span multiple difficulty levels — from beginner-friendly tasks to advanced problems for experienced international teams.

Pwn

Binary Exploitation

Memory corruption, heap grooming, ROP chains, and the fine art of making a program do what it was never meant to.

Reverse

Reverse Engineering

Disassemble, decompile, and dismantle the protections guarding compiled software. Understand the machine.

Web

Web Exploitation

Authentication flaws, injection, broken logic, and the kind of bugs that live quietly in production.

Crypto

Cryptography

Classical puzzles, modern primitives, and mathematical challenges that reward creative attacks over brute force.

Forensics

Digital Forensics

Memory dumps, packet captures, and hidden artifacts. Reconstruct what happened, byte by byte.

OSINT

Open-Source Intelligence

Follow the trail across the open internet. People, domains, metadata — everything leaves a trace.

Misc

Miscellaneous

The unconventional ones. Weird formats, strange rules, and problems that only reward out-of-the-box thinking.

All skill levels

all seven?
