There have been some rogue Android APKs that are impersonating the TraceTogether app.
When you unwittingly download and launch these fake contact tracing apps, your mobile device could be hacked and personal data stolen.
You should always download the official TraceTogether app only from the Google Play Store and Apple App Store. Ensure the app you are downloading is developed by “Government Technology Agency”.
Download links to the official app can also be found here.
