ptrace-inject is a tool for injecting code into a running process using
ptrace. It is a tool for *nix systems - for Windows, see dll-syringe.
Currently, only x64 is supported, but support for other architectures is planned
as soon as I can test them.
ptrace-inject is both a Rust library and a command line tool. Here's an example
of using the library:
use std::{process::Command, path::PathBuf};
use ptrace_inject::{Injector, Process};
let library = PathBuf::from("path/to/library.so");
// Spawn a new process and inject the library into it.
let target = Command::new("target-process");
Injector::spawn(target)?.inject(&library)?;
// Or attach to an existing process.
let proc = Process::by_name("target-process")?.expect("to find target process");
Injector::attach(proc)?.inject(&library)?;See the documentation for more information.
The usage of the command line tool is as follows:
Usage: ptrace-inject [OPTIONS] <--name <NAME>|--pid <PID>> <LIBRARY>
Arguments:
<LIBRARY> Path to the library to inject
Options:
-v, --verbose... More output per occurrence
-q, --quiet... Less output per occurrence
-n, --name <NAME> Name of a process to attach to
-p, --pid <PID> PID of a process to attach to
-h, --help Print help
-V, --version Print version
You can install it with cargo install ptrace-inject --features cli.
