Enter theByte
Buff3r Bytes runs competitions worth turning up for and a lab worth staying in. Every solve comes back as a debrief, every path you find gets drawn, and your skill map tells you the truth about where you are.

Public events, community nights and private corporate rounds — all on the same engine.

Featured work
One from each discipline. The library holds considerably more.

A scoreboard is the least interesting part of a CTF
Six things this platform does that a scoreboard does not. They are the product, not features bolted on the side.
Attack Graph
The path you find gets drawn as you find it. Nodes stay hidden until you discover them, so the graph is a record of your progress rather than a spoiler.
Hacker Journey
A capability tree instead of a number. Recon, injection, access control, pivoting — each one unexplored, learning, practised or mastered.
Adaptive Difficulty
Platform difficulty is one number. Yours is another. We estimate it from what you have already solved — never from anything that would give the answer away.
Investigation Mode
Some challenges hand you logs, captures, artefacts and a timeline to build. Mark evidence, form a hypothesis, then call it. It is a small SOC, not a text box.
Challenge DNA
Every challenge carries a technical fingerprint. Find work by concept, not category — and authors can see exactly where their coverage is thin.
Post-Solve Learning
Solving does not end at "correct". You get the technique, what actually happened, the skill you just banked and where to go next.
Live hacker activity
The ticker starts as soon as the first flag lands.
Taken first
Every challenge is still unclaimed.
