You work with the Tamil Nadu Cyber Crime team in Chennai. A group of hackers has been sending encrypted messages to coordinate their activities. Your senior officer assigns you to crack their communication system. The hackers think their codes are unbreakable, but you know that every cipher has a weakness.
Your job is to study their encryption methods, find the patterns, and decode the hidden messages. Each message you crack brings you closer to stopping their operations. The investigation starts with simple ciphers, but you must stay sharp as the challenges grow harder.
Open your terminal and begin the decryption work.
