Here is a list of tools I use to conduct open source intelligence (OSINT).
TweetDeck is a social media dashboard application for management of Twitter accounts. I use TweetDeck to monitor accounts, hashtags, and keywords of interest. It’s free and easy to setup and use. You can use boolean operators to help narrow down the content and filter your content with basic features.
Feedreader is a browser based RSS reader. What I like about it is you can create separate categories for different types of feeds, allowing you to monitor and organize different types of information. You can create RSS feeds out of Google Alerts, Google News, and other types of aggregators. This will allow you to automate a lot of your news collection tasks.
MyMaps by Google is a bare-bones GIS app that allows you to create custom maps for projects you are working on. I like it because I can quickly plot markers for locations of interest in an area I’m investigating and reference them when collecting information that is geotagged. It also allows you to create different layers to organize the markers based on type. It has limitations, such as the amount of markers you can put in each layer and the lack of support for Google Street View within the app.
Namechk is a great tool that allows you to find out if a username you are investigating is used elsewhere online. It includes various social media platforms as well as domain names and mobile apps.
ADS-B Exchange is the world’s largest source of unfiltered flight data. Normally, blocked tail numbers from private airplanes aren’t visible. With ADS-B Exchange, you can access all the information from any tail number you want. This is great for tracking politicians, business leaders, etc. to find connections between them or any associated event.
There are far too many Google Chrome Extensions to name, but it’s important to create a toolkit of useful extensions to help you collect data while doing investigations. A good place to start is Treeverse for analyzing Twitter conversations. If you want to spend some coin, I recommend getting Hunchly. It’s an all-in-one investigation tool that runs in your browser!
