Hey guys, I’m trying to compile a source code from breaking security. It is a tool for running .bin files in memory. Anyway I used GCC for compiling it and I get some errors, I don’t really have much experience in programming in general so any help telling me how to fix it and compile it my self would be much appreciated[code]// ________________________________________________//// ShellLoad.c//// PURPOSE:// Useful tool to test shellcodes.// The program will load the shellcode from file and execute it into its own process memory.// 3 different shellcode loading methods are provided as option.//// USAGE:// Execute the program passing the shellcode file path as parameter.// 2° parameter is optional and lets you define the preferred shellcode loading method:// 1 = Inline ASM (Default)// 2 = C Function// 3 = CallWindowProc////// RELEASE NOTES:// v1.0.0// 27 Jul 2021//// AUTHOR:// © BreakingSecurity.net // https://BreakingSecurity.net// ________________________________________________#include #include // Shellcode Entrypoint function prototype// TIP: We can edit this function to support different return types and parameterstypedef INT(*ShellEntry)();#define METHOD_INLINEASM 1#define METHOD_CFUNCTION 2#define METHOD_CALLWINDOWPROC 3int main(int argc, char *argv[]){ int ret = 0; int mtd = 1; int err = 0; DWORD fsize = 0; printf(""); printf("-------------------------"); printf(" Shellcode Loader v1.0.0"); printf(" BreakingSecurity.net"); printf("-------------------------"); printf(""); if (argc < 2) { printf("USAGE MODE:"); printf("ShellLoad.exe path"); printf("ShellLoad.exe path method"); printf(""); printf("METHODS:"); printf("1 = Inline ASM (default)"); printf("2 = C Function"); printf("3 = CallWindowProc"); printf("EXAMPLE (default method): ShellLoad.exe \"C:\\shellcode.file\" "); printf("EXAMPLE (select method): ShellLoad.exe \"C:\\shellcode.file\" 1"); printf("------------------------"); printf("[-] ERROR: No parameter passed.
