Description

A simple project created by me to be used as a loader in smaller/personal projects

Features:

• Download/Execute application from URL
• Checking a specific key to allow download
• Hiding the application downloaded
• Pinging/Checking if given website is alive

How To Use

This project is made for/in C++17

• Simple Menu Class Usage

Menu menu("Title") //creates a menu with a title given
menu.add_item(anything) //moved add_item to template

• Downloader Usage

download_file_from_url(src, dest, hidden) //downloads a file from a url to a destination and can be hidden
open_app_insecure(DESTINATION, args, b_hidden) //opens a file from destination with specific arguments (put "" if none).
ping_new(PING_DEST) //ping a website with a given destination (url/ip?)
ping_old(PING_DEST) //not recommended to use. Does the same as above
is_key_allowed_insecure() //check if given key is allowed returns true or false

Usage of is_key_allowed/insecure:

lets say you need to check whether the user has access to your product or not you would need some kind of a serial id from the user trying to download the product you can upload the key in any format, on any website, in any extension. I will use 1111-3 as an example, so i upload a file.txt to my web hosting with 1111-3 written in it, and than call is_key_allowed_insecure() with key_input being a string entered by the user

• Example

if (!is_key_allowed_insecure(key_input)) { menu.add_item(xorstr_("wrong key.")); return 0; }
else { menu.add_item(xorstr_("key correct.")); }

is_key_allowed_insecure being a boolean value may be vulnerable to backtracing. Currently working on is_key_allowed_secure().

Directories and Links

All website links/urls can be changed in includes.h
Directories can be changed in utils.h -> get_path()

Example Program:

#include "downloader.h"
#include "utils.h"
#include "xor.h"
#include "simple_menu.h"

int main() {
	Menu menu(xorstr_("Title"));

	std::string key_input;
	std::cin >> key_input;

	if (!ping_new(PING_DEST)) {
		std::cout << xorstr_("[-] Website not responding, exiting.\n");
		pause_until_leave();
	}

	if (!is_key_allowed_insecure(key_input)) { menu.add_item(xorstr_("wrong key.")); pause_until_leave(); }
	else { menu.add_item(xorstr_("key correct.")); }

	std::cout << xorstr_("[+] Website up, proceeding\n");

	std::cout << xorstr_("[*] Downloading...\n");

	if (download_file_from_url(FILE_SOURCE, get_path(), false)) {
		std::cout << xorstr_("[+] File downloaded and stored in: ") << get_path() << "\n";
		pause_until_leave();
	} 
	else {
		std::cout << xorstr_("[-] Couldn't download file\n");
		pause_until_leave();
	}

	return 0;
}
