About this lab

This is a simple XOR-based program designed for laboratory reverse engineering practice. Its purpose is to evaluate and strengthen your ability to inspect compiled code, analyze program logic, identify data transformations, and independently develop scripts or tooling to reproduce the original functionality.

By working through this exercise, you can practice key reverse engineering skills such as static analysis, dynamic testing, recognizing XOR encoding patterns, and automating decryption or reconstruction tasks. The goal is not only to solve the challenge, but also to identify gaps in your methodology, improve analytical thinking, and build confidence in writing your own supporting scripts during technical investigations.
