Baking Your Anomalous Cookies - Jim Allee NolaCon 2019 (Hacking Illustrated Series InfoSec
Baking Your Anomalous Cookies Jim Allee
I hacked Fortnite! Actually it was a vulnerable cookie found on several domains owned by Epic Games that allowed me to hijack traffic of users of their websites, steal session tokens and of course, BeEF hook em'. I will describe my journey from creating a custom cookie fuzzing tool (Anomalous Cookie) to help identify vulnerable cookies, to creating a framework for 'Cookie Baking'. Cookie Baking is the technique of creating or modifying a cookie in a users' local Cookie Jar (this includes stuffing with malicious payloads, affiliate tags, fuzz-strings and more). I will also provide insight into the Bug Bounty process, how Google responded to my request for them to protect local cookies at rest, and how I created WHID-Injected Cookies! ;)
