IOS app runs with root privileges

1. Add at the main function of the program

setuid (0);

Setgid (0);

2. Modify the executable file (because the app does not allow root permission to run when the application is booted)

Open the. App, find the executable file in it, copy it, and replace it with a bit of content.

#!/bin/bash
root=$ (dirname "$")
exec "${root}"/textxt_

(Note punctuation)

(principle: Use this script to guide our program, the script is not root permission, so can pass)

3. When you package Deb, the Postinst script is written to Deb, and the Postinst script reads as follows: (The script is to modify the permissions of the executable in the package when it is copied to the application directory)

#!/bin/bash

CD "/applications/textxt.app/"

# process Origin Binary
Chown Root.wheel Textxt_
chmod +s Textxt_
chmod +x Textxt_
