 |
|
| If I were to add bytes to the end of an exe, it would not get loaded into the memory. Is there a way to load more bytes at the end?

So you want to make the exe bigger but not load those bytes into the memory? Or do you wánt to load them into the memory?
If you want to load them in the memory I guess you could make one of the sections bigger, or add a few extra sections.
If you only want to make the file bigger, just add the bytes to the file and make sure the PE header stays correct.

| consider adding a new section but you'd need to edit section headers, etc. too and cff explorer is a good tool for that.

| I still don't get the purpose... but you could also add a custom file as a resource. For example you could have a random file of any type, which might be any size, like 10 mb, and you could add it as a resource, and your exe size will be a lot bigger.

| Create a file with all the same characters, keep going until it's the size you want. It may compress to nothingness as well depending on what you use as well

adding a bunch of nops at the end of the program should make the size bigger without messing up the program..
so just get a file to load up in ur C++ program as binary then get filesize of it and filesize +1 +2 +3 etc.. how big you want to make it +1024 would add around 1KB and keep adding 0x90 using strcat() and fputs() or something
but u dont have to get filesize etc.. if you open the file in append mode so it will end bytes to end anyways..
something like
| Code: |
int count = 0;
FILE* file;
char buffer[5000];
file = fopen ("smallvirus.exe","ab"); //b for binary i dont think it matters
buffer[0] = 0x90
for(int i=0;i<1024;i++) {
strcat(buffer, 90);
count++;
}
buffer[count] = '\0';
fputs (buffer,file);
fclose (file);
|
but i dont know if it will work might be different things in the header that gotta be changed as well..

#include <Imagehlp.h>
#pragma comment(lib, "Imagehlp.lib");
#define ExtraBytes 1024
LOADED_IMAGE li;
bool isDll = false;
if( MapAndLoad("ImageNameWithoutExtension","ImagePath",&li,isDll,false))
{
HANDLE pImg = CreateFileMapping(
-1,lpAttributes,PAGE_EXECUTE_READWRITE
,0,li.SizeOfImage+ExtraBytes,"ImageMap");
memcpy(pImg,li.MappedAddress,li.SizeOfImaege+ExtraBytes);
MapViewOfFile(pImg,FILE_MAP_ALL_ACCESS,0,0,li.SizeOfImage+ExtraBytes);
}

got bored...
