The StrongPity APT hacking group is distributing a fake Shagle chat app that is a trojanized version of the Telegram for Android app with an added backdoor.

Shagle is a legitimate random-video-chat platform allowing strangers to talk via an encrypted communications channel. However, the platform is entirely web-based, not offering a mobile app.
