We're building Depi Red Team.
Zero to a validated exploit in 3m 56s. Depi does the recon and validation, the red teamer builds the exploit locally on top.
We also used Bug Bounty as a sandbox for our research and got XX,XXX$ bounties with it ;D
Our team went from hours or days to minutes on the hardest exploits.
I need help from Red Teamers and get some feedback. DM me what's missing or let's jump into a call ;D

Recently, I've been looking at DOMPurify again, trying to find ways to bypass 3.x.x after browsers started encoding attrs during serialization.
I ended up with a nice ≤3.2.6 Safari default-configuration bypass using only SMIL tags/attrs :D

Big update: Subdomain enumeration now uses separate quotas for each plan!
This means MORE data for the same price. Plus, our free tier still lets you discover hundreds of subdomains monthly - no payment required.

Guillaume Chouquet, fondateur et directeur de l'ESNA, viré de sa propre école par l'@Formation_bzh !!!
Je suis consterné et en colère.
C'est affligeant de prendre une telle décision quand on sait tout ce que le bonhomme a fait pour l'école et les alternants !

The wiki lets you filter gadgets by browser, tags, attributes, CSP, and timing, making it as easy as possible to find interesting vectors (at least I hope so!) 🔎

I'm happy to release a script gadgets wiki inspired by the work of @slekies, @kkotowicz, and @sirdarckcat in their Black Hat USA 2017 talk! 🔥
The goal is to provide quick access to gadgets that help bypass HTML sanitizers and CSPs 👇

Today was my last day as a pentester at Bsecure, and it feels a bit surreal. After a three-year journey of hunting on the side, I’m finally ready to go all-in as a full-time bug bounty hunter.
To celebrate this milestone, I've written an article sharing the full story. It’s a transparent look at the path that got me here: the wins, the lessons, the real financial numbers, and my honest advice for anyone considering this adventure.
You can read all about my journey from pentester to full-time hunter here: gelu.chat/posts/from-pentest…

I'm very happy to finally share the second part of my DOMPurify security research 🔥
This article mostly focuses on DOMPurify misconfigurations, especially hooks, that downgrade the sanitizer's protection (even in the latest version)!
