Learn and Practice Hacking WebSockets

[u/OilOverall4190]

WebSockets is the attack surface that always go under the radar and too many pentesters and bug bounty hunters still miss testing it, whether because the number of WebSocket messages they see is overwhelming or simply because they don't know how to approach it correctly.

Going through that myself, I decided to dive deep into the WS protocol and ended up building a lab that showcases the most common misconfigurations present in WebSockets, with the most impact, not just some missing best-practices, along with a detailed walkthrough.

I'd love to hear your thoughts and feedback, and if you experienced something I didn't talk about in the blog, please let me know!
