Adding 'free' bytes to an existing file.

[zerith]

Hello, i would like to add some bytes to an existing program, so i can execute them later in the reversed program.

how would i do such a thing?

would i have to mess with the file system? the root directory? or can i just modify the size of the file with a tool like OLLYDBG?

thanks in advance.

You can simply open the file in a hex editor and add a string of zeros to the end of the file until you have the space you need for your extra bytes.

Thank you for your reply, but how does an Hex editor do it? i also want to know how.

^ Hello. Zero_Add seems pretty useful for ASProtect inlines (MapViewOfFile + wipe the added section details from PE header) ;-) I usually use CFF Explorer.

Cheers!
