Crack Agent's Weak SSH Password

HydraHydraBeginner
Practice Now

Introduction

In this challenge, you'll step into the role of a security professional tasked with recovering a compromised SSH password for a secret agent. The goal is to use Hydra, a powerful password cracking tool, to identify the weak password protecting the agent's account.

The challenge involves setting up a local environment with a user named 'agent' and a predefined list of common passwords. You'll then leverage Hydra to target the local SSH server at 127.0.0.1, using the username 'agent', the password list agent_passwords.txt located in the ~/project directory, and 8 threads to accelerate the cracking process. Successful completion requires executing the correct Hydra command and verifying that it identifies the password "weakpassword".

Crack Agent's Weak SSH Password

A secret agent's SSH password has been compromised and needs to be recovered quickly. Your mission is to use Hydra to crack the password and restore secure access.

Tasks

  • Use Hydra to crack the SSH password for the user agent on the local machine 127.0.0.1 using the password list agent_passwords.txt.

Requirements

  1. You must use Hydra to perform the password cracking.
  2. You must target the local SSH server at 127.0.0.1.
  3. You must use the username agent.
  4. You must use the password list file agent_passwords.txt located in the ~/project directory.
  5. You must use 8 threads (-t 8).
  6. You must execute the command from the ~/project directory.
  7. You must save the results to ~/project/hydra_results.txt.
  8. You must use the -o option to save the output.

Examples

To view the results after running Hydra:

cat hydra_results.txt

Example output format:

[ssh] <ip>:22 - login: <username> password: <found_password>

Hints

  • Remember to specify the target IP address and the SSH service.
  • Use the -l option for the username and the -P option for the password list.
  • The -t option controls the number of threads.
  • The -vV options provide verbose output.
  • Use the -o option to save the results to a file.
  • Make sure to save the results to ~/project/hydra_results.txt.

Summary

In this challenge, the objective is to crack a weak SSH password for the user 'agent' on the local machine using Hydra. The setup involves creating the 'agent' user with the password "weakpassword", generating a password list file named agent_passwords.txt containing common weak passwords, and ensuring the SSH service is running.

The task requires using Hydra with specific parameters: targeting the local SSH server at 127.0.0.1, using the username 'agent', specifying the password list file agent_passwords.txt, and utilizing 8 threads. The successful execution of Hydra should reveal the correct password, "weakpassword", for the 'agent' user, which can be verified by checking the Hydra output for the string "login: agent password: weakpassword".
