09 – Preventing Debugging by using SystemFunction40 (RtlEncryptMemory) on DbgUIRemoteBreakIn

The video discusses the conclusion of a series focused on anti-analysis techniques in executable code. The presenter reflects on the learning journey and provides insights into a specific function related to debugger prevention mechanisms. He walks through how the function manipulates memory protection settings to scramble a debugger’s access points, ultimately concluding with an invitation for further engagement from viewers.

**Key Points:**

The video is the final part of a series on anti-analysis techniques.

The presenter explains a specific function that prevents debuggers from attaching to the code.

It details the process of changing memory protections using the ZW Protect Virtual Memory function.

The function targets the debug UI remote break-in to make it writable and then encrypts its initial memory bytes.

This scrambling of memory aims to thwart debugger operations by corrupting the function’s code.

The discussion includes references to system function calls and memory manipulation techniques.

The presenter invites viewer feedback for potential future content and expresses hope that the audience learned valuable skills throughout the series.

The video hints at further possible explorations into the binary’s behavior and where it conceals strings and encryption methods.
