Scripting and automation are absolutely critical to many aspects of an attacker’s effectiveness, penetration tester or otherwise. Modern WAFs and “bot detections” often add a small layer of intelligence to their monitoring, attempting to determine whether or not an attack is being automated, and shut the bot/botnet down. This presentation will be a mini-tutorial on how the various forms of “bot detection” out there work, and how to modify/spoof the necessary client environments to bypass nearly all of them using anything from Python Requests to Selenium, Puppet and beyond.
