Threat researchers at antivirus giant Avast discovered seven apps on the Google Play Store that were apparently all built by the same Russian developer. It writes that they could be used to stalk employees, romantic partners, or kids without their knowledge.
Avast reported all of the apps to Google as soon as they were discovered. The tech giant quickly removed them from its Play Store, but they had already been downloaded a total of 130,000+ times, with two of them— Spy Tracker and SMS Tracker—each having gained over 50,000 installs.
