HackTheBox Traverxec

Traverxec is rated as an easy box on HackTheBox. User As with all HackTheBox machines I started with an nmap scan which identified port 80 was open and running nostromo 1.9.6, a simple HTTP server also called nhttpd.

50m CTF write-up

On the 26th of February HackerOne announced ‘the biggest, the baddest, the warmest’ CTF, with an incredible price of 10.000 US$. Being a beginner hacker my first reaction was: ‘with that kind of price, I’ve no chance in hell to solve it!’. However, since I love playing CTFs I took a shot anyway. This is …
