is a challenge that emphasizes thorough enumeration and identifying common web development "fails"—such as exposed configuration files, weak credentials, or insecure script handling. 1. Phase I: Reconnaissance & Enumeration The first step is identifying the attack surface. Network Scanning : Run a comprehensive scan to identify open ports. nmap -sC -sV -oA hackfail_initial Use code with caution. Copied to clipboard Web Enumeration hackfail.htb /etc/hosts file. Use tools like to find hidden directories. Common "Fail" Targets : Look for directories, config.php.bak files that might reveal source code. 2. Phase II: Vulnerability Analysis
Here is a summary of the typical attack path for this machine: 1. Initial Reconnaissance
Navigating to http://hackfail.htb in a browser reveals a custom web application. To find hidden directories and files, run a directory brute-forcing tool like Gobuster or Feroxbuster: hackfail.htb
ffuf -w /usr/share/wordlists/dirb/common.txt -H "Host: FUZZ.hackfail.htb" -u http://hackfail.htb -fs Use code with caution.
Running OpenSSH. Useful later for persistent access if credentials are found. is a challenge that emphasizes thorough enumeration and
Using these credentials, log in via SSH to obtain a stable user session and retrieve the user flag ( user.txt ). 4. Privilege Escalation to Root
"data": "Ä\x00\xFF"
Now that you have a foothold as www-data , it's time to escalate your privileges to the root user. The path to root on Falafel is a multi-stage process involving several interesting techniques.
Before browsing the web application, add the host mapping to your /etc/hosts file: echo " hackfail.htb" | sudo tee -a /etc/hosts Use code with caution. 2. Web Application Enumeration Network Scanning : Run a comprehensive scan to
