Unsealed court filings reveal Meta's secret plan, "Project Ghostbusters," to acquire valuable intel about Snapchat through its users' devices.

Thus, Project Ghostbusters was born. It’s Meta’s in-house wiretapping tool to spy on data analytics from Snapchat starting in 2016, later used on YouTube and Amazon. This involved creating “kits” that can be installed on iOS and Android devices, to intercept traffic for certain apps, according to the filings. This was described as a “man-in-the-middle” approach to get data on Facebook’s rivals, but users of Onavo were the “men in the middle.”
