# /mnt/ain challenge library

363 challenges from Swiss and international events, kept by the Swiss national hacking team. We work through them one category at a time.

Ongoing challenge library. Organized by /mnt/ain, the Swiss national hacking team. Running since 27 October 2026.

3 solved so far, from a library of 363 challenges.

## In short

### What it is

The open challenge library of /mnt/ain, 363 challenges from the Swiss Hacking Challenge and other events.

### What we test

The Offensive Lab, one category at a time, with every solve written up.

### What it shows

Real competition challenges solved by the lab, each one explained.

## About the benchmark

/mnt/ain, read as mountain, is the Swiss national hacking team. Its library collects challenges from Swiss and international events, such as the Swiss Hacking Challenge, each with its original files and a live instance where one is needed.

Unlike an event, the library has no clock and no scoreboard. That makes it a steady place to rerun the same challenges after every improvement and see whether the lab got better.

## What it tested

### Category by category

Web, reversing, cryptography and more, measured one at a time.

### Repeatable

The same challenges rerun after each change, so progress shows as a number.

### Written up

Every solved challenge gets its own page on how the lab got there.

## The result

Three challenges solved so far. More categories follow.

## Every challenge
