In languages such as C#, you need to use something called Platform Invoke or PInvoke for short when you want to use certain Windows APIs since they’re not native to the language. Learning malware development in C++ took me down the road of reflective DLL injection, which is much more difficult than it sounds. In this post we have walked through the malicious Macro within a captured Excel file, which downloads Emotet via two extracted files, “uidpjewl.bat” and “tjspowj.vbs”.

You can look through the source codes that were previously used to build the program by using a decompiler program. The DLL file extension is used by many applications and software programs. They store code and objects and allow programs to access them. You can open DLL files using a decompiler to view the code inside them.

Errors happen when an application can’t find a file and cannot run without it. However, some programs specify DLLs that are needed to run and will return an error message if they cannot be accessed.
