Leaked documents reveal that Facebook used the devices of some of its teenage users to spy on its competitors through a secret project launched in 2016. The documents allege that Facebook paid teenagers to install spying tools on their devices.
The documents indicate that Facebook used malware to intercept and decrypt data from Snapchat, YouTube, and Amazon applications. This data included application analytics, such as the number of active users and user behavior.
It is believed that Facebook used this information to improve its own products and stifle competition. The documents also allege that Facebook servers were used to create fake digital certificates to impersonate application servers in order to redirect data traffic.
