HackTheBox - Eureka (Protected)

It’s been a while! Time to get back to hacking.

Eureka is a good “Hard” Linux machine that made me learn a few new tricks. This box was a fun challenge, needing good enumeration, a bit of knowledge about Java Spring Boot problems, and a smart way to look at how services find each other to get the user flag. The path to root then moved to a cool ████████████████, showing that even simple-looking █████████████ can lead to privesc. In the end Eureka was a well-made box and a great way to learn, especially about common Spring issues and tricky exploits. Definitely one to try if you like a challenge with a few steps!

Tl;Dr: █████████████
