Introduction
As our journey through the Bandit Challenge continues, Level 15 ↗️ presents us with a new challenge. Instead of directly retrieving the password, we’re required to submit the current level’s password to a specific port on localhost.
By understanding port communication, networking principles, and employing tools like nc (netcat), we’ll gain access to the next password.
Challenge Overview
Level 15 challenges us to submit the password of the current level to port 30000 on localhost. Our task is to establish communication with the specified port and provide the necessary password.
By using networking tools like nc (netcat), we’ll send the password to the designated port, and in return, we’ll receive the password for the next level.
Approach and Strategy
Follow these steps to successfully solve Level 15
Enter the password you obtained from the previous level.
Submit the current level’s password to port 30000 on localhost using the nc (netcat) command:
echo {current_level_password} | nc localhost 30000Replace {current_level_password} with the password you obtained for the current level. This command sends the password to the specified port.
The output of the command will display the password for the next level. Take note of it for the next level.
Notes
- Ports are communication endpoints used in networking to facilitate data exchange.
- The nc (netcat) command is a versatile networking utility that can be used for various network-related tasks.
Conclusion
Congratulations on successfully completing Level 15 of the Bandit Challenge! By submitting the current level’s password to port 30000 on localhost, we gained access to the password for the next level.
Stay tuned for the next blog post, where we’ll tackle Level 16 and face new challenges as we continue our journey to become proficient cybersecurity practitioners.
