PreviousOffensiveNextHow to Perform SSH Brute Force Attack and How Can We Protect Our Systems from It?

Use what I'm about to say in this article only for the right purposes, such as raising security awareness and improving the security posture of your environments. I do not accept any responsibility for other uses.
Enum4Linux is a tool used to collect information from Windows and Samba systems. Some information that Enum4Linux can collect;
->Shared files and directories of the target system, ->Working users and groups of the target system, ->NetBIOS name and IP address of the target system, ->Operating system version of the target system, ->Security settings of the target system.
Enum4linux is a tool written in Perl language used in collecting information in penetration tests. So let's talk about how we can use it.
-> Kali Linux ->Metasploitable
First of all, deploy Metasploitable, a vulnerable Linux variant, to your environment. Metasploitable's default username and password is "msfadmin". Log in with this information.
Let's see which ports are open by starting an nmap scan from our Attacker machine.
As we see, our SMB ports are open on the target machine. This means that we can continue to look for vulnerabilities in these ports with enum4linux.
The -U parameter is used to list the users on the target.
We can see the status of shared environments by using the -S parameter.
As you can see, we understand that we have access to the <Target-IP>/tmp directory and have permission to list it.
We can see the status of password policy informations by using the -P parameter.
We can check the status of NetBIOS services using the -n parameter.
We can check the all SIDs using the -r parameter.
->Turn off unused services, ->Staying away from vulnerable protocols, ->Use strong passwords, ->Delete unnecessary users from the system,
Metasploitable does not have a graphical interface by default and I used Metasploitable in one of my previous articles, "", where I explained another vulnerability, the Shellshock vulnerability.
