Cerbero

Cerbero is a command line tool designed to perform brute force attacks against SSH and FTP services. This tool can be useful for security audits or penetration tests where the resistance of access credentials needs to be tested.

Directorybrute

Main Features

  • Support for brute force attacks on SSH and FTP services.
  • Ability to manage multiple users and passwords through files or direct entries.
  • Option to list users across known vulnerabilities in SSH versions.
  • Thread management to improve performance during attacks.
  • Intuitive and easy-to-use command line interface.

Requirements

To run Cerbero, the following dependencies are required:

  • Python 3.x
  • Libraries Python:
    • paramiko
    • ftplib
    • colorama

You can install the dependencies by running:

To install only the tool cerbero.py

./requeriments.sh

To install only the tool cerbero_only_ssh.py

./requeriments_only_ssh.sh

Use

Basic Usage Examples

SSH attack with a specific username and password:

 python3 cerbero.py -H <target_ip> -u <username> -p <password> -s ssh

SSH attack with a user and password dictionary:

 python3 cerbero.py -H <target_ip> -u <username> -P <file_passwords> -s ssh

SSH attack with a user dictionary and specific password:

 python3 cerbero.py -H <target_ip> -U <file_usernames> -p <password> -s ssh

SSH attack with a user dictionary and password dictionary:

 python3 cerbero.py -H <target_ip> -U <file_usernames> -P <file_passwords> -s ssh

FTP attack with a user and password dictionary:

 python3 cerbero.py -H <target_ip> -u <username> -P <file_passwords> -s ftp

FTP attack with a user dictionary and specific password:

 python3 cerbero.py -H <target_ip> -U <file_usernames> -p <password> -s ftp

FTP attack with username and password files:

python cerbero.py -H <target_ip> -U <FILE_USERS> -P <FILE_PASSWORDS> -s ftp

SSH or FTP attack with username and passwords using various combinations on the user:

 python3 cerbero.py -H <target_ip> -u <username> -P <file_passwords> -s ssh -e n s r

Explanation

n: Deals with a null password attempt.

s: Use the username as a password.

r: Reverses the username and uses it as a password.

Available options

-H, --host: Specifies the IP address of the destination host.

-s, --service: Defines the service to attack (ssh or ftp).

-u, --user: Provides a single user for authentication.

-p, --passwd: Provides a one-time password for authentication.

-U, --user-file: Specifies a file with a list of users.

-P, --passwd-file: Specifies a file with a list of passwords.

-t, --threads: Number of threads to use to increase the speed of the attack (default: 5).

-o, --output-file: Saves the results to a specified file.

-c, --success-continue: It continues with the next valid username/password combination after finding one.

-e, --extra-params: Additional parameters to customize user/password combinations.

-en, --enumerate-users: Attempts to enumerate users by exploiting known vulnerabilities in SSH versions.

Running as Root

To run Cerbero with all necessary permissions, it is recommended to run it as root or with equivalent privileges, especially if low ports are required or multiple simultaneous connections are made.
