In April 2017 we started observing new rooting malware being distributed through the Google Play Store. Unlike other rooting malware, this Trojan not only installs its modules into the system, it also injects malicious code into the system runtime libraries. Kaspersky Lab products detect it as Trojan.AndroidOS.Dvmap.a.
The distribution of rooting malware through Google Play is not a new thing. For example, the Ztorg Trojan has been uploaded to Google Play almost 100 times since September 2016. But Dvmap is very special rooting malware. It uses a variety of new techniques, but the most interesting thing is that it injects malicious code into the system libraries – libdmv.so or libandroid_runtime.so.
