I created a two scripts for port network scanning. If 22 is open, then script tries to provoide a brute-force attack. If it cracks the password, writes it in the command line.

Simple network scanner and port 22 brute force script in python

Both scripts perform a port scan on a user-specified IP address and identifi open ports. If port 22 is open, it prompts the user to perform a brute force attack to gain unauthorized access to the SSH server.

Script_1

How does it work.

1. Imports the necessary libraries - scapy, paramiko.
2. Defines the target IP address, port range, and an empty list to store open ports.
3. Defines functions for scanning a single port, checking the reachability of the target IP address, and performing a brute force attack using a password list.
4. Calls the main function, which scans for open ports on the specified IP address.
5. If port 22 is open, it prompts the user to perform a brute force attack. If the user agrees, the script performs a brute force attack using a list of passwords from a file named "PasswordList.txt".

Script_2

1. Libraries - argparse, socket, paramiko

The program starts by parsing the command line arguments and constructing a list of ports to scan. It then scans each port using the scan_port function and builds a list of open ports. If port 22 (the SSH port) is open, it reads the list of passwords from the specified file and attempts to brute-force the SSH login using the ssh_brute_force function.

The scan_port function uses the Python socket module to create a TCP socket and attempts to connect to the specified port on the target host. If the connection is successful, it returns True, indicating that the port is open. Otherwise, it returns False.

The ssh_brute_force function uses the Paramiko library to attempt to connect to the SSH service on the target host using the specified username and a list of passwords. It loops through the password list and tries each one until it finds one that works, at which point it prints a message indicating that the login was successful and returns True. If none of the passwords work, it returns False.

Note

Script appears to be a security vulnerability scanner, and the brute force attack is potentially harmful and illegal if used without permission. Therefore, it is important to use such scripts ethically and legally.
