NMAP Scripts: Unveiling the Power Behind Network Scanning

Let’s kick things off with a simple question: Ever wondered how cybersecurity pros dig deep into networks to find possible security vulnerabilities? The answer lies in the usage of NMAP scripts, these powerful tools are the hidden gems in the NMAP cybersecurity toolbox. But what exactly are they? Let’s explore!

What Are NMAP Scripts?

NMAP, or Network Mapper, is a renowned network scanning tool used for security auditing and network discovery. It comes pre-installed with Kali Linux and it is often used in pentesting.

While NMAP itself has a lot of function, you might come into sitations, where you want to scan specific items like a potential CVE that has just been released.

In these situations, it is the fastest way to create a NMAP script that can search for the specifics of that CVE.

Be cautious when downloading NMAP scripts — always verify the code and see what it does before running it.


These scripts are little programs written to extend the capabilities of NMAP, allowing it to perform a wide range of tasks from vulnerability detection to advanced network mapping.

The Scripting Engine: Heart of NMAP’s Flexibility

At the heart of these scripts is the NSE (NMAP Scripting Engine), a potent feature that allows users to write (or use pre-written) scripts to automate a wide range of network tasks.

These tasks could be anything from detecting open ports, CVE’s, to identifying the operating systems running on remote hosts.

Categories of NMAP Scripts

NMAP scripts are categorized 5 groups based on their functionality:

  1. Discovery: These scripts are used to gather more information about hosts on a network.
  2. Vulnerability Detection: Identifies vulnerabilities in systems.
  3. Safe: Scripts that are non-intrusive and safe to be run against any host.
  4. Intrusive: Potentially harmful scripts that should be run with caution.
  5. Malware Detection: For identifying malware-infected hosts.

As you can see, these categories, can also be applied to the cyber kill chain pretty simple.

Using NMAP Scripts

To use an NMAP script, you need basic knowledge of command-line interfaces and NMAP syntax.

For instance, a simple command to use an NMAP script could look like:

nmap --script=[script name] [target]

Replace ‘[script name]‘ with the name of the script you want to use and ‘[target]‘ with your target host or network.

Custom Script Creation

What’s more exciting? You can create your own scripts! If you know Lua (the language used to write NMAP scripts), the sky’s the limit.

You can tailor scripts to your specific needs, making your network exploration as broad or as targeted as you desire. Within a couple of years or months, you will have an arsenal of powerful NMAP scripts that you can use in your daily work.
