   2a. Studied the basics of the Selenium Webdriver and learnt simple
browser automation techniques on Firefox - interaction with the
webpage and other pool of actions.
   2b. Ported basic actions to Tor Browser. Facing some issues with
integration which I hope to rectify in a day or two and push.

Next two weeks will involve:

1. Integrating randomized actions on Tor Browser with Exitmap.
Creating a pool of possible ways to interact with the web service to
make it difficult for the malicious Exit node to suspect scanner

2. Add test cases to added interactions and observe changes in scanner
output from the initial simple usage of urllib2 actions and assert the

I apologize for the delay in submitting my first report.
