IRS (Impersonate-RS)

💡 IRS es una versión como librería de https://github.com/zblurx/impersonate-rs, zblurx

Reimplementación de Defte Impersonate en Rust puro. Para obtener más información al respecto, consulta este blogpost.

El enfoque de suplantación de tokens es un poco diferente al de Defte Impersonate: aquí tienes que seleccionar un PID del que quieras suplantar el Token Principal, y luego irs.exe:

Duplicará el token
Creará un named pipe (para obtener la salida de la ejecución)
Ejecutará el comando con el token seleccionado mediante CreateProcessWithTokenW y enviará el resultado al named pipe
Recogerá la salida del comando desde el named pipe
Imprimirá la salida del comando

Este enfoque te permitirá suplantar a cualquier usuario en el equipo de destino siempre que tengas privilegios de administrador (no se necesita NT SYSTEM) y se puede usar con o sin GUI.

`exec`

El comando exec abre el id de proceso indicado en el argumento pid, duplica su token y ejecuta un comando con el nuevo token.

[2025-10-13T20:59:42Z INFO  irs::impersonate::exec] Impersonate user NT AUTHORITY\SYSTEM

Ejemplo de exec

`spawn`

El comando spawn duplica el token del pid seleccionado y lanza un nuevo proceso usando ese token duplicado.

PS C:\Users\maldev\Desktop> .\irs.exe exec --pid 708 --binary "C:\Windows\System32\cmd.exe"
[2025-10-13T20:59:42Z INFO  irs::impersonate::exec] Impersonate user NT AUTHORITY\SYSTEM

Ejemplo de spawn

`library`

O directamente en tu proyecto Rust de la siguiente manera:

Cargo.toml:

[dependencies]
irs = { path = "/data/02-GIT/github/impersonate-rs/", version = "1.0.0" }

O con el repositorio de GitHub:

[dependencies]
irs = { git = "https://github.com/g0h4n/impersonate-rs", version = "1.0.0" }

main.rs:

use irs::*;

fn main() {
    // List process
    impersonate::privileges::enabling_sedebug().expect("[!] Failed to run enabling_sedebug()");
    token::enum_token().expect("[!] Failed to run enum_token()");
}
