The "anonymity" of free (and paid) VPN services has always been in question.
The news confirmed this once again.
1.2 TB of data leaked about users of Secure VPN, Fast VPN, Free VPN, Super VPN, UFO VPN, Rabbit VPN, Flash VPN. Moreover, including data on the IMEI of the phone, email. mail, statistics of the resources visited via VPN, etc.
Naturally, nothing is free, and services massively collect information about the user for sale to companies engaged in Internet analytics and advertising. And when you have a lot of data, sooner or later they will also get into the public domain, like this time.
The danger is that when installing mobile applications, such services may try (but do not seem to do so yet) set their SSL certificate as the root one (by the way, antiviruses do this all the time). Then the data transmitted over HTTPS may be at risk.
