04 Learn Applications DLL Hijacking in 50 Minutes (Practical Demo)

⚠️ LEGAL DISCLAIMER ⚠️ This video is for EDUCATIONAL PURPOSES ONLY. Unauthorized access to computer systems is illegal under the Computer Fraud and Abuse Act (USA), Computer Misuse Act (UK), and similar laws worldwide. In this video, I'll show you exactly how application DLL hijacking works - from theory to a full working exploit with persistence. We start with the basics: what DLLs are, how Windows loads them, and why the search order creates a massive security hole. Then I walk through the complete attack chain using Spotify as the target application. What you'll learn: How dynamic link libraries (DLLs) work in Windows Using Process Monitor (Procmon) to find missing DLLs Understanding DLL search order and exploitation paths Writing malicious DLLs in C++ with proper export forwarding Cross-compiling DLLs with MinGW Establishing C2 communication without admin privileges Creating persistence through registry keys and startup folders Why user-writable paths (AppData) are better targets than Program Files The best part? This entire attack works with low privileges. No admin access needed for persistence. I hit some walls during this (like Windows Defender catching the payload), made mistakes, and had to pivot strategies multiple times. I kept all of that in the video because that's how real pentesting works. You troubleshoot, you adapt, you find another way. Tools used: Process Monitor (Procmon) for DLL enumeration MinGW for cross-compilation PowerShell for automation Discord webhook as C2 (demo purposes) Note: Windows Defender bypass and advanced evasion techniques are out of scope for this video - that's a whole separate topic we'll cover later. For this demo, Defender is disabled to focus on the core technique.
