Find Your Foe

Continuing from my last post, I learned a few tricks by watching some video from DefCon 18. Everyone has a web browser. You can use the browser to deliver software to users.

FaceBook has a feature where the client checks whether a user's friends are online or not. This is just an HTTP request to FaceBook. Good stuff to know.

Here was the finale of the talk I watched. Create a web page with malicious code. Have a piece of JavaScript that inquires the MAC address of the user's router.

The MAC address is set in hardware. It cannot be changed. Once you have the user's MAC address, you can send it to Google. Then Google will tell you where the router is located geographically. Bamm. You can track the people who come to your web paged. Owned.
