CTF Challenge

Sledgehammer

Name: Sledgehammer
Brand: CodeRed

This challenge demonstrates how attackers perform brute-force password cracking against an SSH service to gain initial access to a compromised Linux server. It highlights the process of identifying weak credentials, exploiting insecure authentication mechanisms, and successfully establishing unauthorized remote access to the target system.

Challenge Overview

The Security Operation Centre (SOC) of the company had detected that a Cybercrime-as-a-Service group had compromised a company production server and had removed the original access of the system administrator from the system. The system had then isolated from the production network by the security analyst. Unfortunately, the compromised system contains essential company data and must be retrieved. As a Cybersecurity Analyst in an external security consultant team hired by the company, your task is to penetrate the machine and retrieve the critical files. This experience requires knowledge of enumeration, password cracking, and red team methodologies. Players will demonstrate skills with Hydra and SSH hacking as username ‘john.’ The target machine runs on a Linux Ubuntu OS with an IP address of 10.10.1.183. Your task is to discover and exploit the system’s vulnerabilities and perform various attack techniques to gain administrative access.
