## Summary

A walkthrough of the Brooklyn Nine-Nine CTF machine on TryHackMe. The process covers enumeration with nmap (discovering FTP, SSH, HTTP), steganography analysis of a web image using steghide and stegcracker to extract credentials, anonymous FTP login to find user hints, SSH brute-forcing with nmap scripts, and two privilege escalation paths using GTFOBins exploits for the 'less' and 'nano' commands running with sudo NOPASSWD.
