Crooks slinging mobile trojans have reverted to old techniques by stealing users’ money through WAP-billing services. The “unusual” rise in mobile trojan clickers that steal money from Android users through Wireless Application Protocol (WAP) billing has been tracked by security researchers at Kaspersky Lab. The unexpected trend had been in evidence for a while, but in Q2 of 2017 it became surprisingly common, with thousands of affected users in different countries across the globe, mainly in India and Russia, according to Kaspersky Lab.
