Android.Harly in virus library:

Android.Harly is a family of trojan applications targeting Android OS-based devices. Their primary task is to silently subscribe users to various paid services. For this, they covertly load webpages of various services and carry out automatic subscriptions. During this process, various modifications of the Android.Harly family are capable of sending SMS, automatically making phone calls, and executing USSD requests.

Functionality-wise, these trojans are similar to trojans from the Android.Joker family, and they have a modular architecture. However, in many cases, they do not download additional modules from the Internet but already have them stored in their resources in an encrypted form. During an attack, these components are decrypted and executed. In addition, unlike Android.Joker trojans, they usually do not intercept notifications.

Attackers embed Android.Harly trojans into copies of initially harmless games and applications and spread them as new software via the Google Play catalog.
