For example, Instagram only allows us to upload photos if it thinks we are a mobile device, meaning we can upload from our computer if we set our user agent to one of a smartphone. To get around this, we can use a user-agent switcher to pretend to be a different device.Īside from the privacy benefits, we can also change the behavior of webpages by pretending to be a specific device. Unfortunately, this can also leak a lot of data about you and uniquely fingerprint your device. To load webpages, your browser will send information about the device making the request to send you a version of the website you are requesting that is most appropriate for the device you are using. Using browser plug-ins to study previous versions of the internet opens up information to discoveries that might not be available anywhere else. More Info: Use the Buscador OSINT VM for Conducting Online Investigations.Using these extensions in a virtual machine will better isolate yourself from potential identifying information that your primary OS may leave behind. I also recommend, as you can see in our video, that you install Buscador OS as a virtual machine since it has all of these browser extensions installed already. Make sure your version is fully updated, then go to the Google Chrome Web Store or the Firefox Add-ons webpage to locate extensions to add to your browser. To follow this guide, you'll need to download Google Chrome or Mozilla Firefox. EXIF extractors let you pull data from any images you find, data-formatting tools allow you to tap into APIs and read the data more efficiently, and there are tools to dig into archived versions of the internet to access historical data that has since been deleted. You can even get websites to behave differently depending on how you identify your system while requesting webpages, which can be useful for a variety of situations.įor OSINT researchers, browser extensions provide a way to dive into the data on the internet to learn more about every clue you find. By taking control of the information a browser is sending while making requests to load websites, you can better maintain your privacy and prevent easy tracking across the sites you visit. An example is the Grammarly browser extension, which automatically corrects spelling and grammar errors.Īside from correcting spelling, browser extensions can do some pretty incredible things. The easiest way to think about browser extensions is to picture them as apps for your browser, with specific extensions providing add-on functions that make the browser more useful for a particular use-case. What Are Add-Ons?īrowser extensions, or add-ons, are programs that expand what a browser can do. These are a list of my top ten favorite browser extensions for hackers - and how to use them. For hackers and OSINT researchers, these tools can be used to defeat online tracking, log in to SSH devices, and search the internet for clues during an investigation. While modern browsers are robust and provide a lot of functionality, they can be unlocked to do some pretty spectacular things with browser extensions.
