UEFI is the new BIOS
Learn about UEFI reverse engineering and exploit development so that you too can build the skills necessary to find and exploit UEFI bugs, understand common UEFI vulnerabilities, and better secure the firmware security supply chain.
The Unexpected Benefits of Threat Modeling
Threat modeling is a disciplined approach to technology design that identifies security threats and design constraints to prevent security flaws before they manifest in your platform.
Bypassing SSRF Filters Using r3dir
We demonstrate how to use the r3dir tool to bypass some SSRF filters. r3dir is a convenient redirection service made for SSRF filter bypasses.

Vulnerability Research and the Importance of Supporting Young Talent
This is a story with a happy ending where we were able to get back to the collaboration from the early open disclosure days, utilize modern practices to ensure responsible handling of the information, and allow a young person to make a positive contribution to infosec.
Encoding Bitwise Functions as Polynomials
Use polynomials to represent Boolean functions, see how they can be solved using generic math, analyze the properties of the representation, and use them to construct an arithmetic logic unit (ALU).
