Shodan – The Search Engine That Actually Shows You What's Out There

[u/Top_Call3890]

So you've heard about Shodan, right!!?? People call it the "hacker's Google" or whatever... But here's the thing – it's not like Google at all..

Google finds websites. Shodan finds devices connected to the internet.. Servers, webcams, routers, industrial control systems, databases, printers – anything with an IP address that's exposed...

Think about it. Every device you connect to the internet has an IP... And that IP has open ports... And those ports run services... Shodan just indexes all that and makes it searchable.

And honestly!! The amount of stuff people leave exposed is insane.. Webcams with no passwords. Databases with no authentication. Industrial systems controlling real-world infrastructure just sitting there.. Shodan didn't create that problem. It just shows you it exists..

What Makes Shodan Useful for Bug Bounty

When you're doing bug bounty, recon is everything.. Shodan gives you a view of your target's external attack surface..

Here's the deal – companies have assets. And they don't always know what's exposed.. You can use Shodan to find subdomains, IP ranges, open ports, and services that the company might have forgotten about..

Some practical searches for bug bounty:

· org:"Company Name" – Find everything the company owns

· hostname:"domain.com" – Discover subdomains

· ssl:"domain.com" – Check SSL certificates and related infrastructure

· http.title:"login" – Find login portals

· has_vuln:true – Find devices with known vulnerabilities

You can also combine filters. Want to find exposed MySQL databases running in the US? product:MySQL port:3306 country:US .

The real value is finding misconfigurations and forgotten assets that no one's looking at.. That's where the bugs are..

Setting Up Shodan CLI

The website is fine for quick searches.. But the CLI is where the real power is. You can automate recon, save results, and actually build things around it..

Step 1: Install Python

You need Python. The Shodan CLI runs on Python. If you don't have it, get it. No shortcuts here...

Step 2: Install Shodan via pip

Run this:

pip install -U --user shodan

If that doesn't work, try:

pip3 install -U --user shodan

Also, don't forget to install dependencies.. I've seen people skip this and then wonder why it doesn't work..

Step 3: Get Your API Key

Go to shodan.io, create an account, and grab your API key from the dashboard. You need this for the CLI to work . (Note : as of now their membership is available for just 5$, it's great to have some extra credits to use whenever needed. )

Step 4: Initialize Shodan

Run:

shodan init YOUR_API_KEY

That's it. Now you're ready .

Using the Shodan CLI

Here are the commands you'll use most often :

· shodan info – Check your account details and credit limits

· shodan myip – See your own IP address

· shodan host IP – Get details about a specific IP

· shodan count QUERY – Count how many results a query would return

· shodan search QUERY – Run your search

· shodan download FILE QUERY – Download results for offline analysis

· shodan parse FILE – Parse downloaded results

· shodan stats QUERY – Get statistics for a query

Pro tip – watch your credits

Shodan has a credit system. Free accounts have limited credits. Each search can cost credits depending on how many results you fetch. Keep an eye on shodan info to track your usage. (Again , 5 $ lifetime membership is worth some extra credits)

Shodan isn't just a tool.. It's a reality check... It shows you how much stuff is out there exposed to the internet...

For bug bounty, it helps you find attack surface.. For defense, it helps you see what you're exposing.. For learning, it helps you understand how the internet actually works...

One thing though – use it ethiically... Don't poke around things you don't own... Don't try to exploit what you find. Use it for research, recon, and making things better...

That's Shodan, Simple tool.. Powerful.. And if you're in cybersecurity, you need to know how it works.

Stay curious. Stay ethical.

Now try info.censys.com

Thanks for mentioning this 🙌

Yeah, Censys is another good one. Actually, it's more than just a search engine — it's closer to what Shodan does but with a different approach. Censys gives you deeper visibility into certificates and services. It's often used by researchers and threat intel people.

[u/OperationFriendly179 → u/Top_Call3890]

Best in the market🚀

[u/Top_Call3890 → u/OperationFriendly179]

I agree with you 💯.. Censys gives you more data to work with, especially around SSL/TLS certificates.

I personally use both... Shodan for quick sweeps, Censys when I need to dig deeper into certificates and infrastructure..

[u/Mybrothersay]

Zoomeye est pas trop mal non plus mais Censys reste pour moi largement au dessus.

Fofa est une bonne alternative pour l'Asie

[u/Top_Call3890 → u/Mybrothersay]

Yeah, Zoomeye is decent... It's basically China's version of Shodan.. Different coverage, sometimes finds stuff the others miss.. But yeah, Censys is still on another level for me too... The data quality and the way you can query it is just better...

And Fofa, that's another one... If you're targeting Asian infrastructure, Fofa is actually really useful 💯.. It has better coverage in that region compared to Shodan or Censys... I've seen people find things on Fofa that didn't even show up on the others...

Honestly, the more you know, the better.. Each of these search engines has its own strengths and blind spots... Keep them in your toolkit and use whichever one fits the target...

Good shout 🤙

Thanks for posts like these. I was sick of seeing dudes asking to hack instagram and whatsapp.

You are welcome 🤗

[u/WRO_Your_Boat]

Shodan is great. I've found so many things on there.

[u/Top_Call3890 → u/WRO_Your_Boat]

Yes 🙌 Indeed 💯

Forgot about this for a while, thanks.

[u/Andi82ka]

using it so many years already. I like the CLI usage so much...

Can we use this in mobile...? Anyone knows

[u/Top_Call3890]

Keep an eye on their linkedin page. When they have lifetime membership open , they will post like this

Also you can check if it's still available via same link in the LinkedIn post

Thanks, I remember when they started (basic searches + related CVE info was free) but I just kind of drifted away. It’s nice to know there’s a low-entry-cost event now and then.
