Writeup for some retired HTB mobile ctf

Lattice attacks are a concept I encountered while participating in CTFs.

The purpose of this post is to demonstrate how I interpreted a basic lattice attack and how I constructed it's lattice base.

An introduction to the Hash Length Extension attack, showcasing how to implement it manually and the idea behind it.
