Mobile dropper Trojans are one of today’s most rapidly growing classes of malware. In Q1 2019, droppers are in the 2nd or 3rd position in terms of share of total detected threats, while holding nearly half of all Top 20 places in 2018. Since the droppers’ main task is to deliver payload while sidestepping the protective barriers, and their developers are fully bent on countering detection, this is probably one of the most dangerous classes of malware.
