Hey HN,
A few weeks ago, I realized that I was sitting on over 3 billion entries of data breaches published on the Darknet due to my day job as an ethical hacker/red teamer.
So, I created DoHackersKnow.Me, a tool that lets you query those entries by email, phone number, or your name. This way, you can see yourself through the eyes of an attacker and understand what information is accessible about you.
The tool is written in TypeScript and uses Tailwind & DaisyUI for styling.
