Psiphon 3, an Internet censorship circumvention tool was initially released for the Android operating system. This app lets you use Internet exceeding the normal limits. It uses a combination of SSH, VPN, and Proxy technology.
When you launch the Psiphon app, it will automatically start connecting to the Psiphon network. Psiphon is running in VPN or Whole Device mode. All applications are tunneled through Psiphon. To run Psiphon in Tunnel Whole Device mode, you must have Android 4.0+ or a rooted device.
Psiphon is not good at providing security or privacy. The provider is open about this: Psiphon is designed to provide you with open access to online content. Psiphon does not increase your online privacy, and should not be considered or used as an online security tool.
When you use Psiphon, we hide your IP address as soon as you connect – and we don’t store it anywhere. We have no user accounts so do not collect or store any account access information. … Psiphon is not explicitly designed to ensure the integrity of your traffic over the Internet.Bandwidth in all free versions of Psiphon is limited to 2 Mbps. There is also a Psiphon Pro app, which shows even more prominent ads. … The “maximum speed” plan increases your speed limit to 5 Mbps.
Behind the scenes, however, the rogue version of Psiphon is running the Triout malware which then steals the users’ data. It’s also bundled with three pieces of software that hijack the phone to make bogus ‘visits’ to websites hosting ads.
