The first time I ran Nikto, I wasn’t trying to be clever—I was trying to fix something I didn’t understand.
A friend asked me to help check if his new WordPress site was “secure enough.” I had no clue what that actually meant. I’d heard about tools like Burp Suite and Nessus, but they felt like overkill (and honestly, intimidating). Then I stumbled on Nikto. A single terminal command, and boom—my screen lit up with warning signs, outdated software alerts, and all the things a bad actor would drool over.
I was shocked. So, I pointed it at one of my own websites.
Worse. Much worse.
Outdated server headers. Open directories. Leaky information. I had walked into the ethical hacking rabbit hole through the front door—completely unprepared, but hooked.
If you’re new to web security or you’re just starting to explore the power of tools like Termux, Nikto is one of the simplest, fastest, and most powerful ways to understand what your web server is silently telling the world—and how to stop it.
In this guide, I’ll walk you through what Nikto is, how it works, and how to start using it today—even if you’ve never scanned anything before.
By the end of this, you won’t just understand why Nikto matters—you’ll have the confidence to run your first scan, read the results, and take action.
Ready to see what your server’s been hiding? Let’s get started.

What is Nikto, Really?
Nikto is a free and open-source web server scanner designed to find vulnerabilities in websites by performing comprehensive checks against thousands of potential issues. Think of it as a security guard that walks around a building checking all the doors, windows, and locks—except it’s doing that for your web server.
It doesn’t require deep cybersecurity knowledge to get started. With just a few commands, Nikto can detect:
- Insecure or outdated software
- Misconfigured headers
- Dangerous scripts and files
- Common security holes and exploits
And the best part? Nikto is light, fast, and completely usable in Termux—making it perfect for mobile pen-testing setups or learning ethical hacking without a full-blown laptop.
Key Features of Nikto
- Extensive Plugin Support: Nikto supports numerous plugins that enhance its scanning capabilities, allowing users to extend its functionality according to their specific needs.
- Multiple Scan Types: Users can perform full scans, specific target scans, and utilize various reporting formats, making Nikto adaptable to different scanning scenarios.
- Active Development: Being open-source, Nikto is continually updated by its community, ensuring it stays relevant against new vulnerabilities and security challenges.
Why Use Nikto? (And When You Should)
When I started exploring ethical hacking, I didn’t know where to begin. I didn’t have expensive Kali Linux gear or advanced tools—and frankly, it was intimidating.
Nikto changed that.
It gave me a way to start scanning my own servers and learn what real-world vulnerabilities look like. It’s an ideal first tool for:
- Beginners exploring ethical hacking
- Devs wanting to audit their own web apps
- Students preparing for CTFs or cybersecurity challenges
- NGOs or small orgs that can’t afford commercial scanners
If you’re already using Termux, Nikto becomes even more practical. You can run full vulnerability scans directly from your Android device—no VM, no dual-boot, no drama.
How Nikto Fits into Your Termux Setup
If you’re using Termux as your hacking lab (and you should—it’s FOSS, fast, and portable), here’s a quick note on installing Nikto:
pkg update && pkg upgrade
pkg install git perl
git clone https://github.com/sullo/nikto.git
cd nikto
chmod +x nikto.plTo run a quick scan:
perl nikto.pl -h http://your.target.siteMake sure you’re using a server you own or have permission to scan. More on that in a bit.
Nikto vs Other Scanners
You might be wondering: “Isn’t that what Nmap does?”
Not quite.
| Tool | Focus | Great For |
|---|---|---|
| Nikto | Web server vulnerabilities | Apache/IIS config checks, outdated software |
| Nmap | Network mapping & port scanning | Finding open ports, OS detection |
| Dirbuster | Directory brute-forcing | Discovering hidden web files/directories |
| Burp Suite | Full web app security suite | Intercepting traffic, testing login forms |
Nikto is the lightweight but sharp tool in your kit—it’s fast, focused, and perfect for scanning web servers and spotting common misconfigurations.
Play It Safe: The Ethics of Scanning
Before you fire up your first Nikto scan, read this carefully:
Never scan websites you don’t own or explicitly have permission to test.
Unauthorized scanning can:
- Get your IP blacklisted
- Violate computer crime laws (e.g., RA 10175 in the Philippines, CFAA in the US)
- Damage live servers if misused
Nikto is a powerful tool, but with that comes responsibility. Stick to your own sites, staging environments, or platforms that allow security testing. Ethical hacking is about protecting—not breaking—things.
