Challenge Overview

A cybercrime group known as the 3N16M4GG surfaced recently and has been actively attacking financial institutions sectors for monetary gains. Unfortunately, the bank you had been working for received an email from 3N16M4GG demanding ransom. Your role as a Penetration Tester in the security department of the bank is to identify and exploit any potential vulnerabilities in the production system to test the readiness of the bank's infrastructure. This challenge requires knowledge of NOPASSWD Sudoer exploitation, privilege escalation, directory brute force, credential attack, PHP file upload, and web exploitation. Demonstrate SSH passphrase key cracking and remote code execution. The target machine runs on a Linux Ubuntu OS with an IP address of 10.10.1.212.

What You Will Learn

  • Identifying open services and hidden directories using tools like Nmap.
  • Exploiting insecure file upload functionality to achieve remote code execution via a PHP reverse shell.
  • Recovering and cracking an SSH private key to gain authenticated access to the system.
  • Using obtained credentials to log into the system and perform further enumeration.
  • Exploiting NOPASSWD sudo privileges (e.g., sudo -i) to gain full root access on the machine.
