Nebula level 02 is even cooler than the previous two. Every level brings something new and allows you to challenge yourself. Check it out!
Nebula is the first VM of exploit-exercises.com. I highly recommend it for those who want to practice vulnerability assessment, privilege escalation and exploit development in Linux systems. Open to read more about it and challenge yourself. There are 20 levels in total. I’ll try to guide you through them starting from level 00.
