Whenever you visit a website, your browser could be making hundreds of connections to other URLs in the background. These connections could be loading media, displaying ads, or deliver potentially malicious code. This video will show you how to analyze all the connections your browser makes when you access a website.

You’ll learn how to use the browser’s developer tools to record website network traffic, extract URLs using a Powershell script, and analyze any suspicious links with VirusTotal. This workflow is especially useful for incident responders or security researchers who need to understand the various connections a website makes when people connect to it.
