Injex

• aims to provide a library in rust to alter other processes
• at the moment only linux is supported, if i enter a state where i am satisfied with the linux implementation i will look at OpenBSD/Mac/Windows
• freezes the process by sending signal or CGroups
• edits the memory of target process by procfs or process_vm_readv/write syscall

Example

use injex::prelude::*;
use std::path::PathBuf;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let pids = find_process_by_name("target").unwrap()[0]; 
    // Freezer: SignalFreezer or CGroupFreezer
    // Manipulator: ProcManipulator or ProcessVMManipulator
    inject::<CGroupFreezer, ProcManipulator, PathBuf>(
        pid,"lib.so".into()
    ).unwrap();
    Ok(())
}

CLI

build:

cargo build --release --example injex

Usage:

Gives users the possibility to inject into and manipulate processes

USAGE:
    injex <--pid <PID>|--name <NAME>> <LIBRARY_PATH>

ARGS:
    <LIBRARY_PATH>    The library to inject

OPTIONS:
    -h, --help           Print help information
    -n, --name <NAME>    The name of target process
    -p, --pid <PID>      The pid of target process
    -V, --version        Print version information

Example:

injex -p 12345 ./injection.so # inject the injection.so into pid 12345
injex -n a.out ./injection.so # inject the injection.s into the process of which name is 'a.out'
