IRS (Impersonate-RS)

💡 IRS è una versione libreria di https://github.com/zblurx/impersonate-rs, zblurx

Reimplementazione di Defte Impersonate in puro Rust. Per maggiori informazioni, consulta questo post del blog.

L'approccio all'impersonazione dei token è leggermente diverso da quello di Defte Impersonate: qui devi selezionare un PID di cui vuoi impersonare il token primario, poi irs.exe dovrà:

Duplicare il token
Creare una named pipe (per ottenere l'output del comando)
Eseguire il comando con il token di destinazione tramite CreateProcessWithTokenW e inviare l'output alla named pipe
Recuperare l'output del comando dalla named pipe
Stampare l'output del comando

Questo approccio ti consente di impersonare qualsiasi utente sul computer di destinazione purché tu abbia privilegi di amministratore (non è necessario NT SYSTEM) ed è utilizzabile sia con che senza GUI.

Compilazione

Esempio di lista

`exec`

Il comando exec apre l'ID del processo target nell'argomento pid, ne duplica il token ed esegue un comando con il nuovo token.

X:\>whoami

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

PS C:\Users\maldev\Desktop> .\irs.exe exec --pid 708 --command "whoami /all"

Esempio di exec

`spawn`

Il comando spawn duplica il token del pid selezionato e avvia un nuovo processo utilizzando tale token duplicato.

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

Esempio di spawn

`library`

Oppure direttamente nel tuo progetto Rust, ad esempio:

Cargo.toml:

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

Oppure con il repository 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()");
}

Per vedere tutte le funzioni disponibili, usa il seguente comando per aprire la documentazione Rust.
