"Security Researchers Warn of Joker Malware's Resurgence in Play Store Apps"

Despite Google's efforts to secure the apps it distributes through the Play Store, cybersecurity researchers regularly discover malicious, malware-laced apps masquerading as harmless and download-worthy on the platform. The Joker malware, a spyware Trojan that allows bad actors to exploit victims and install additional dangerous malware on compromised devices, has been one of the more persistent threats. The malware has reappeared, having been discovered in Play Store apps with over 100,000 combined installs. Researchers at Pradeo discovered Joker malware in four Play Store apps: Smart SMS Messages, Blood Pressure Monitor, Voice Languages Translator, and Quick Text SMS (via SamMobile). They then notified Google, resulting in the apps being removed from the Play Store. However, as the apps had over 100,000 installs between them, many users may be at risk. Those who downloaded the apps are urged to uninstall them immediately because hackers can use them to infect Android devices with other types of malware. The Joker Trojan, which was first discovered piggybacking on Android apps in 2017, is designed to go undetected when a user downloads and installs an app. The Joker malware was initially reliant on SMS fraud, which cost its victims money. It has since evolved into a powerful hacking tool that can be used to intercept one-time passwords and security codes, take screenshots, make calls, access contacts, record device information, send SMS messages, and more without the victim's knowledge. This article continues to discuss the reemergence of the Joker malware in Play Store apps, the history of this malware, and its capabilities.
