It is a 2 year old video when I am watching it. The best part of the video is, Tomnomnom has explained things in pretty detailed way. Another thing I noticed from starting to end of the video is that, Tomnomnom is the calm teacher and Stok is the curios student, where the curiosity reflects in his eyes. Just loved it. ❤

[@getbrutal4388]

While modern frameworks are initing their routing you can go into the debugger and pause it, build a new config, and get yourself into some hidden sections of the apps. If there's content in those section that is not protected by a token, you're gonna get some free stuff! Could be video lessons, pdfs, who knows. The key is that you're building your own custom route config for an app. This takes a good understanding of the routing engines of the frameworks as well as the product you're trying to get into.

[@dixztube]

Where can I learn more about this?

[@kottunaana]

@@dixztube I think having a sound knowledge about API frameworks (such as ExpressJs) and vulnerabilities that arise due to not using token validation (such as CSRF) will give you a good understanding.

Finally bridging the gap between web developers and cybersecurity engineers. Well done. Some notes to self: 1. Be mindful that once something is on the internet--someone is always watching. 2. Always make sure sensitive information (such as passed credentials) are not visible to the public. 3. Change up the folder structure and resource filenames of applications.

Totally agree! Trolling through now trying to find more videos of him explaining things

[@TheRockacer22]

This is what i understood from this: Best way to go about exploiting javascript webcode is exploit the one thing most admins in the industries demand, pretty easy to read code with same formatting across all code/functions of a project. If you can learn what their habits are you know what to look for and what they might call/name certain objects you shouldn't be modifying. If you know all their user based api calls start with USER_ID_ than you can search for that and find crumbtrails back to an api call you can change or change the designation of an object's information.

[@victortodoran1828]

Dude. In the minify process variable names an methods are stripped to bare letters. What are you talking abt?

[@TheRockacer22]

@@victortodoran1828 most minify processes for JavaScript only get rid of some variable names , it mostly gets rid of whitespace. Hence why the dude in the video was using pretty print to view the code.

[@nicolaslaborie5015]

"Always a pleasure my friend". Great :) You two are a perfect combination as teachers. Music and editing is great, great chemistry and Tomnomnom is very easy to follow. It's a pleasure learning this unknown subject, thanks to you.

At the end of the video, he said this golden sentence "you gotta be able to make things work the way they're supposed to first before you could make them work the way they aren't" and that's how it is. Do not learn "hacking" since there is no such thing. Learn how to design web apps then try to break it and what youclearn while doing so, makes you a hacker

[@anakinskywalkerrr]

I love the background music, make it more dramatic and interesting, than boring hip hop beat
