*PINCHERSOFPERIL and BULLYBUSTER are WIP

DATA scripts are a constant work in progress. Feedback, issues, and additions are welcomed.

Proper python packages will be created once suffecient testing and features have been added and more bugs have been squashed.

Troubleshooting

Make sure you are using the latest versions of Firefox, Selenium, and Mechanize. Selenium and Mechanize can be upgraded via pip.

sudo apt-get update && sudo apt-get install firefox
sudo pip install mechanize --upgrade
sudo pip install selenium --upgrade

The current version of geckodriver tested is v0.19.1.

If you have pcap writing issues, use this to fixup dumpcap perms, observed when using some VPS

sudo chgrp YOUR_USER /usr/bin/dumpcap
sudo chmod 750 /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin+eip /usr/bin/dumpcap

Be sure to disable NIC features when capturing traffic run this as root. Checksum errors will cause all sorts of nightmares.
