Meta Used Its Onavo VPN to Snoop on Users’ Encrypted Snapchat Traffic

Lorenzo Franceschi-Bicchierai, reporting for TechCrunch:

“Whenever someone asks a question about Snapchat, the answer is usually that because their traffic is encrypted we have no analytics about them,” Meta chief executive Mark Zuckerberg wrote in an email dated June 9, 2016, which was published as part of the lawsuit. “Given how quickly they’re growing, it seems important to figure out a new way to get reliable analytics about them. Perhaps we need to do panels or write custom software. You should figure out how to do this.”

Facebook’s engineers solution was to use Onavo, a VPN-like service that Facebook acquired in 2013. In 2019, Facebook shut down Onavo after a TechCrunch investigation revealed that Facebook had been secretly paying teenagers to use Onavo so the company could access all of their web activity.

After Zuckerberg’s email, the Onavo team took on the project and a month later proposed a solution: so-called kits that can be installed on iOS and Android that intercept traffic for specific subdomains, “allowing us to read what would otherwise be encrypted traffic so we can measure in-app usage,” read an email from July 2016. “This is a ‘man-in-the-middle’ approach.” [...]

Later, according to the court documents, Facebook expanded the program to Amazon and YouTube. Inside Facebook, there wasn’t a consensus on whether Project Ghostbusters was a good idea. Some employees, including Jay Parikh, Facebook’s then-head of infrastructure engineering, and Pedro Canahuati, the then-head of security engineering, expressed their concern. “I can’t think of a good argument for why this is okay. No security person is ever comfortable with this, no matter what consent we get from the general public. The general public just doesn’t know how this stuff works,” Canahuati wrote in an email, included in the court documents.

There’s the Facebook we know and love.

In 2018 Apple removed Onavo from the App Store, but the fact that Facebook was using Onavo in this way was known a year earlier.
