How to use FastSSH tool
FastSSH provides various options to perform scans and brute force attacks against SSH servers. Here are a few examples:
To scan a single IP address, use the ‘–scan‘ option followed by the IP address. For example
bash fastssh.sh --scan 192.168.1.1
To perform a brute force attack against an SSH server, use the ‘–bruteforcer‘ option followed by the IP address and the path to the password file. For example
bash fastssh.sh --bruteforcer 192.168.1.1 passwords.txt
Protecting Your Website Against FastSSH
FastSSH can be a powerful tool in the wrong hands. To protect your website against FastSSH attacks, implement the following measures:
- Use strong and unique passwords for SSH authentication.
- Disable password-based authentication and use key-based authentication instead.
- Implement rate limiting to prevent multiple failed login attempts.
- Regularly update your SSH server software to patch any security vulnerabilities.
- Monitor your server logs for any suspicious activity.
