I realized it's hard to keep up in series like that (because of the same picture, maybe?). They all look alike!
I'll try to add more context to each post for that sake.
In level 5 of Nebula wargame we will learn a bit about privileges in Linux, and how you can a private ssh key that you might find in the backup of a compromised computer.

Finally! The fun part starts here. All levels before that were to warm up.
In the level 7 of the #nebula wargame we got the source code of the application. We need to read, understand, and find how to exploit the bug there.

So PortSwigger (folks who made Burp Suite and Web Academy) finally decided to make their own #cert. It costs $99, but if you will purchase it before Dec 15th they reimburse the whole amount. That could kill the eWPT 🤔

This again. I had to postpone all other activities to make it fly… I really doubt that I’ll take any other eLearnSecurity #cert, what a shame
Exploiting a Race Condition vulnerability in the level 10 of #nebula!
p.s. it's a halfway through the series, so I've changed the pic to kinda celebrate that.

Alright, first thing first - this level is broken. Let's admit it - Nebula is a pretty old project, and it seems abandoned now. Anyhow, challenges itself are quite nice, they are twisted in a way that force you to think as an attacker. In my opinion, this…

Hello local nodes,
Today, I'd like to start another series that I'll try to push in parallels with #nebula. I was doing the #Web Security Academy from PortSwigger for quite some time, so I thought why not to write everything down and post it here?
Without a further ado, check this out:
