01Reconnaissance

Every engagement starts with mapping what is reachable. A full service scan of Google Me highlighted the exposed surface and pointed at osint as the most promising entry point.

Enumeration is deliberately exhaustive here — the goal is to leave no service unexamined before committing to an attack path.

nmap — service discovery

$ nmap -sC -sV -oN nmap/initial 10.10.11.42
PORT     STATE SERVICE  VERSION
22/tcp   open  ssh      OpenSSH 8.9p1 Ubuntu
80/tcp   open  http     nginx 1.18.0
$ echo "10.10.11.42 googleme.htb" | sudo tee -a /etc/hosts
$ gobuster dir -u http://googleme.htb -w /usr/share/wordlists/dirb/common.txt -q
/login                (Status: 200)
/api                  (Status: 401)

02Exploitation

Public records tied the handle to an email, and that email to the account holding the flag.

In this osint challenge that translated into a repeatable foothold. OSINT challenge involving researching a fictional person across social media platforms, GitHub, and public records to piece together hidden information.
