In this video I walk through the TryHackMe Jr. Pentesting "Race Condition" room and show how tiny timing bugs can be turned into reliable exploits. You’ll watch me enumerate the vulnerable web app, pinpoint the exact race window, and demonstrate techniques to automate the timing so the bug consistently triggers. I explain the reasoning behind each test, share a simple, repeatable exploit script for the lab, and show how to verify your results safely in a controlled environment. I also cover defensive concepts—why atomic operations and proper locking stop these issues—so you learn both attack and mitigation. This walkthrough is beginner-friendly, practical, and perfect for anyone building real-world pentest skills; follow along in your TryHackMe instance and pause to try each step yourself. Drop questions or your results in the comments and I’ll help troubleshoot.
