With cyber crime and threat actor activity on the rise, it is more important than ever to understand the dark web and monitor it for potential risks or signs of a breach. There are several tools and intel providers that can do this, but they’re not cheap. So why don’t we just do it ourselves? Python can handle simple tasks surrounding dark web scanning and offers more customization for complex tasks. Using strictly free open-source libraries and any system you have available, you can set up an automated scanner and detect threats as they arise. Scan for IP addresses, potentially compromised emails, crypto addresses, and any regex patterns that you desire. Map your findings to the most relevant onion sites and get an understanding of where your adversaries tend to operate. This is just a start. From here, you can go almost anywhere. Let’s get scanning!
