Quote:A new Trojan dropper dubbed xHelper was observed while slowly but steadily spreading to more and more Android devices since May, with over 32,000 smartphones and tablets having been found infected in the last four months.
 
Trojan droppers are tools used by threat actors to deliver other more dangerous malware strains to already compromised devices, including but not limited to clicker Trojans, banking Trojans, and ransomware.

xHelper, dubbed Android/Trojan.Dropper.xHelper by Malwarebytes Labs' researchers who discovered it, was initially tagged as a generic Trojan dropper only to be upgraded to the rank of a fully-fledged menace after climbing into the security vendor's top 10 most detected mobile malware in just a few months.
