#OSINT Workflow Wednesday

Another week, another workflow. This week we’ll take a look at how to build a basic bookmarklet to automate OSINT searches using #javascript. This will be ground floor level stuff, don’t worry!

Let’s go!

Step 1: Create an option for input

Start a new #javascript file and create a variable to accept input for usernames. This will create a prompt when you click the bookmarklet which we'll use to automate our process.

var username = prompt("Enter a username: ");

Step 2: Plug that username into a URL

Create a new variable called fb and add the URL of the site you want to check. This will append the username to the end of the URL which is Facebook in this example.

var fb = "facebook.com" + username;

Step 3: Open the URL in a New Tab

We’ll look at a basic function that’s built into javascript called window. We want to OPEN that URL in a new tab after the username is input which can be done by adding the "_blank" argument like:

window.open(fb, "_blank");

Quick Recap



So far you should have this:


var username = prompt("Enter a username: ");

var fb = "facebook.com" + username;
window.open(fb, "_blank");

That’s it.

Step 4: Minify your JavaScript

We want to minify your #javascript, or make it one line, to prepare it for becoming a bookmarklet. You can easily do this by going to JavaScript Minifier’s website.

Step 5: Create the Bookmarklet

There’s a formula to create a bookmarklet but I found a site called MrColes that does it for you. Simply copy and paste the minified #javascript into this site and drag and drop the bookmarklet to your bookmarks bar.

Step 6: Add more Functionality



You can add additional variables for checking multiple websites and add additional functions to open those websites with one motion. You can also add Google search URLs to automate Google Dorking. The possibilities are endless.

Step 7: Share your Project

Bookmarklets are very basic but are also very useful in many cases. The Expand All bookmarklet I use for Facebook is an example of a sophisticated bookmarklet that’s still free and open source. Share your work!

The formatting got really screwed up here, but it’s still good!
