net-creds

Thoroughly sniff passwords and hashes from an interface or pcap file. Concatenates fragmented packets and does not rely on ports for service identification.

sudo easy_install pip
sudo pip install scapy
sudo pip install pcapy
brew install libdnet --with-python
mkdir -p /Users/<username>/Library/Python/2.7/lib/python/site-packages
echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/<username>/Library/Python/2.7/lib/python/site-packages/homebrew.pth
sudo pip install pypcap
brew tap brona/iproute2mac
brew install iproute2mac

Then replace line 74 '/sbin/ip' with '/usr/local/bin/ip'.
