JS Monitoring, Devtools, and Sport

This past week was focused on analysing and understanding JS on a target. It was also very helpful to find bugs and to exploit them.

I'm also back at my routine here in Paris, which is cool.

JS Monitoring

With a good friend, we decided to start monitoring all the JavaScript of a target we collaborated on together. And it was pretty straightforward using AI to help us build our system.

It's made particularly for the target but it can probably be modified to be useful of some others. Now this way, we're getting everyday all the diff made, we can also choose from what day to another, and see all the differences and compare them.

We faced some issues, like Cloudflare, or the fact that at any change, the names of the variables and the functions were different, but with some tricks, we were able to get something very nice and useful.

Now, instead of scrolling when taking my coffee, I can scroll through a code diff. I don't know which one is better, but it will definitely be a game-changer in the long run.

Before AI, I would have been too lazy to build it only for a target, but now, with a few hours and some thoughts, you can build something very useful that will bring you a lot of bugs.

Devtools

That's something I was using, but not a lot to be honest. Mostly the main stuff, but never on the debugger.

And as I started working more and more with Kevin_Mizu, it was now mandatory to understand what magic he was doing with his dev tools. So he gave me a little course about how to use the features of DevTools, which was very helpful.

Just using the debugger to see where in the code the innerHTML is made, with what filters and how is so much better than just try and retry.

We did find good bugs together, and we had leads to help each other, and at the end, we got good bugs, and some others to come.

A few months ago, I didn't collaborate at all, and I thought that working alone was better for me. But finally, collab is pretty useful as we don't have the same methodology, and it always ends up with pretty good bugs.

Sport

I'm also back in my routine for this week, before going back to Berlin for a few days. I've bought some Tupperware to batch cook again.

After trying PrepMyMeal, which was great, I want to try doing it myself again to see which one is better and cheaper. And as I'm doing a lot of sport, I need to eat a lot, so it's better to do it yourself.

Also, I started going to the gym again. I was focused on running, and my coach told me that it was also great to work on the upper body, so I came back to do it.
