Challenge Overview

A company hires you as a Penetration Tester in a cybersecurity firm. Your task is to identify and exploit potential vulnerabilities in the production system and report to the company. An insider recently hacked the company, which has suffered a substantial financial loss. Part of their mitigation plan after the cyberattack is to perform cybersecurity assessments to strengthen their cybersecurity posture in the future. This challenge requires knowledge of enumeration, Samba service access, privilege escalation, and system misconfiguration. Demonstrate Remote Code Execution and system hacking. The target machine runs on a Linux Ubuntu OS with an IP address of 10.10.1.147.

What You Will Learn

  • Identifying open ports and services on the Ubuntu server to discover potential attack vectors.
  • Locating exposed configuration files or pages that reveal SMB credentials.
