- The Harvester tool is a powerful and free way to scan that footprint.
Your digital footprint is the trail of data you leave on the Internet, including browsing history, social media posts, and online interactions.
What’s out there can be quite disturbing. The list of IP addresses and services associated with the URL you visited can be eye-opening. If you want to know what your footprint actually looks like, there is a handy Python tool harvester That’s what he was made for.

The harvester uses a large number of modules to accomplish this task. You can see the full list on Harvester’s official GitHub page. Trust me when I tell you the list is extensive.
I installed and ran Harvester to check my digital footprint Google.com And he was shocked by the report he gave. The number of WAN addresses of my home network and the IP addresses associated with it Google.com was wonderful. Once the scan completed, it took me two minutes to scroll back to the top of the list.
Wow!
Harvester isn’t the easiest tool to use, and it’s command line only, but if you’re comfortable installing apps using Python’s PIP package manager, you should have no trouble with this tool.
Let me show you how to set up and use the harvester.

Harvester installation
what you’ll need:The only thing you’ll need to install Harvester is Python 3, Python PIP, and Python VENV installed on your operation system of choice – Linux, MacOS, or Windows. Since installing Python varies on each operating system, I’ll demonstrate how to install everything on an Ubuntu-based distribution (Pop!_OS, to be exact).
First you need to open your terminal window and install Python and Python PIP with the following commands:
show more
sudo apt-get install Python3 python3-pip -y
Next, we need to install the Python virtual environment package, which is done with the following command:
show more
sudp apt-get install python3-venv -y
sudo apt-get install git -y
Now it’s time to install the harvester. First, you need to clone the required Git repository:
show more
git clone https://github.com/laramies/theHarvester.git
Change to the newly created directory:
harvester cd

Enable the Python virtual environment with the following two commands:
Python3 -m venv venv
source venv /bin/activate
Install the harvester with:
install pip
You can verify the installation with:
Harvester-H
You should see a list of command-line options for the app.
using a harvester
Using the harvester is quite simple. Let’s say you want to scan google.com. To do this, issue the command:
harvester -d google.com -b all -l 100
Here are the details of the command:
- Harvester – executable to be run
- -d – is the domain you want to scan.
- -b all – The sources you want to use (such as Baidu, Bevigil, Brave, etc.). When declaring all, the harvester uses all available sources.
- -l 100 – Limits the number of search results to 100 (default is 500).
The scan will take some time to run. When it’s complete, you’ll see a detailed list of emails, subdomains, hostnames, IP addresses, and sources.

In my results, I didn’t see too many email addresses, but as far as hostnames and IP addresses, there were a large number listed. When the google.com scan came back with only the domain, subdomain, and IP address, I decided to run the scan on a domain I owned. This time, the results were not as scary; However, it involved two IP addresses, four email addresses, and 40 different hosts.
What can you do?
Completely removing your online footprint is a very challenging task. One way to limit this is to deactivate subdomains you no longer use (I have several subdomains listed in my results that are no longer active) and email addresses you no longer need.
Another useful tip is to use email aliases, such as:
Finally, you can also hide domain registration details. you can use one WHOIS Lookup Service To find out any information related to the domain you own.
