Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

Explanation of Shellshock posted January 2015

Here's an awesome explanation of shellshock: https://bitbucket.org/carter-yagemann/shellshock/src/f0a88573f912?at=master

This repository contains useful documents which I have written to help educate the cybersecurity community on the "ShellShock" bash vulnerability. These documents are designed to help facilitate learning, including on how to identify possibly vulnerable services and how to remediate such vulnerabilities.

It's actually the clearest explanation I've seen on the subject.
