TryHackMe W1seGuy Walkthrough | Repeating XOR & Known-Plaintext Attack (KPA) Exploit

In this video, we tackle the W1seGuy challenge on TryHackMe. We will analyze the Python server source code, break down how repeating-key XOR encryption works, perform a Known-Plaintext Attack (KPA) using CyberChef, and derive the 5-character key to retrieve both flags!
