Update: The app “Int App Lock” has now been deleted from Google Play and added to global antiviral databases.
Joker is a malware that silently exfiltrates data and subscribes users to unwanted premium subscription. In September, the malware was found in 24 apps on Google Play. Last week, Pradeo researchers identified another infected application still featured on Google Play. The app called Int App Lock, a tool intended to lock access to some data with a PIN code, was installed on 10,000+ devices. Users are advised to immediately delete it from their device.
