Fresh spyware named Joker found in Google’s Android Play Store
Security researchers are cautioning Android phone users of new spyware which hides inside 24 apps within Google's Play Store. These apps have been downloaded across the world 472,000 times, they say. The spyware, dubbed "Joker" was first observed during June this year.
The malware applies treacherous tricks for contaminating the smart-phones belonging to potential targets so it can seize their contact lists, SMS messages, personal and device information along with many other details. Further to compromising the phone's privacy, Joker also secretly creates subscription services for the user alternatively premium paid admission into apps and websites without the user's knowledge.
Aleksejs Kuprins, software developer gives an analysis of Joker, including the way it steals user information within a post on his blog named Medium. The software maker observes that the majority of contaminated applications, inside 37 countries, impacted smart-phones within Asian and European Union nations. Google has since eliminated the 24 applications, which carried the spyware, from the Play. www.abc4.com posted this, September 7, 2019.
Explaining the malware further, Kuprins says that upon installation of any app out of those twenty four malevolent ones, an Android owner would find the ad framework exhibiting the application's logo on one splash screen. Meanwhile, the advertisement framework as well executes many other rogue processes invisible to device owner's eyes. One of these processes is downloading a DEX (Dalvik Executable) file of second stage onto the handset.
A kind of code file, the DEX plants a payload onto the Android OS which then intercepts SMS messages, contact lists, along with other information stored on the smart-phone. During several instances, researchers found the spyware getting victims to sign up to subscriptions for high-profile services like in Denmark victims signed up for services which cost Danish Kroner 50 (approximately EUR7) for every one week.
