Meta Found a New Way to Track Android Users Covertly via Facebook & Instagram (cybersecuritynews.com)

A sophisticated tracking method employed by Meta (Facebook) and Yandex that potentially affected billions of Android users through covert web-to-app communications via localhost sockets.

The technique allowed native Android apps, including Facebook and Instagram, to silently receive browser metadata, cookies, and commands from Meta Pixel scripts embedded on thousands of websites, effectively linking mobile browsing sessions to user identities and bypassing standard privacy protections.

Your computer can have a static IP or a dynamic IP. A static IP is an IP that doesn't change. This could be a cash register. A dynamic IP is a device that you connect to the internet to surf the hub like a tablet. Or your Wi-Fi or any network. And these addresses are needed to direct and identify because without this nothing will work. Now, everybody's local host is most likely, now I don't know everything, but is the same 127.0.0.1 ....... So you can spin up or install a program on a server and use that server's IP address remotely, even though it has its own local address or on your own computer and since you're not connecting to that service remotely, you just use your local address 192.166.3.4 (ip) vs 127.0.0.1 (local host). Now your device is recognized by the router through its Mac address. It's like the computer's DNA. A unique identifier. Which can be spoofed. Shit on top of shit.
