You work with the Tamil Nadu Cyber Crime Investigation team in Chennai. A dangerous criminal group called "The Chain Cartel" operates an illegal cryptocurrency network across the state. They use smart contracts and blockchain technology to hide their money and believe nobody can catch them.
Your team has been watching their digital activities for several months. Recently, the criminals deployed new smart contracts to manage their stolen funds. They think blockchain makes them safe, but your technical team found serious mistakes in their code.
Your mission is clear: break into their digital vault, exploit their security flaws, and collect evidence before they move the money. The cartel stores millions of rupees worth of cryptocurrency. You must work carefully and quickly because they monitor their systems for unusual activity.
The investigation has two phases. First, you will exploit a math error in their token system to gain access. Then, you will use advanced techniques to drain their main vault and secure the evidence. Each step requires you to understand how their blockchain contracts work and find the weak points.
The criminals are confident, but you have the skills to prove them wrong.
