The malicious Swift Cleaner, found in the Google Play store, can send SMS messages, perform ad fraud, and more, according to a Trend Micro report.
For the first time, a malicious Android application built with Kotlin has been discovered in the Google Play store. First noted by Trend Micro researchers in a Tuesday blog post, it’s possible that the app has already been downloaded thousands of times.
In late November 2017, it was reported that 17% of the projects in Android Studio were using Kotlin. Because it’s becoming easier to convert Java code to Kotlin, and the new language features a null-safety feature that can improve app quality, we’ll likely see even more apps developed with the language. However, this also means we could see more malicious apps developed with Kotlin as well.
