NLS Code Injection Through Registry

Created the Monday 20 June 2022. Updated 4 months, 2 weeks ago.

Dll injection through registry modification of NLS code page ID is a technique used by malware to inject a malicious DLL into a process by modifying the NLS code page ID in the registry.

There are two ways to accomplish this technique: 1. Calling the SetThreadLocale function and setting up an export function named NlsDllCodePageTranslation, where the main payload is located. 2. Using the SetConsoleCp or SetConsoleOutputCP functions to modify the code page ID. If the process is not console-based, it is possible to allocate a console using the AllocConsole function.
