Memory allocation/ FileMapping
by snoopy- 3 replies

Guys, Got a question about the following. I have a .exe I want to debug using my own tool. My tool runs the process using CreateProcess, than injects a DLL which sets up a Vectored Exception Handler. Than I can set breakpoints and such and let the DLL trace through the code. Now I am wondering if it is possible to make an exact copy of a .exe and map it into memory. So I can trace through a buffer instead of creating the process and injecting a DLL. What I tried so far: 1. CreateFile 2. CreateFileMapping 3. MapViewOfFile and MapViewOfFileEx.

Protecting file after decryption
by spman- 0 replies

Hi friends I'm producing a secure program. The program opens files with secret contents. suppose the file is video or any other specific format that I don't know about its structure and I use some libraries in my source project to open the file. So I can't make change in the section of code which opens the file. In order to protect the file, encryption is used. But on the other hand, the file must be decrypted to be opened by the program, meaning that the neat file must be passed to the section of program which uses file contents. In the program I do it before passing the file to that section. But in this time the decrypted file is subjected to illegal read. How can I Pr…
