Should I start posting more resources about AppSec? I’m down to start a blog series and GitHub repo if that’s something people would benefit from.

This is a gold mine of knowledge for anyone who is in AppSec or wants to be in Appsec. So many examples of challenges faced in the Modern Application Security Realm and what skillsets to arm yourself with to be impactful.

Throwback to 2016 when I was talking about XXE at a conference and someone said it wasn’t a thing because they had never heard of it. Then it was in the Owasp Top Ten 2017. As of 2023 there are 879 Mitre CVE’s including the word XXE.

Nice approach for discovering XSS vulnerabilities (but also can apply in general as a process for bug hunting 🕵️‍♀️)
One of my first ever bug bounties was an XSS against a WordPress host. It wasn't anything super special but the process I used to find it is one that has yielded loads of bugs over the years. Here's how I found it 👇
