Stealthy Google Play apps recorded calls and stole e-mails and texts


Company expels 20 advanced surveillance apps installed on ~100 devices.

Google has expelled 20 Android apps from its Play marketplace after finding they contained code for monitoring and extracting users' e-mail, text messages, locations, voice calls, and other sensitive data.

The apps, which made their way onto about 100 phones, exploited known vulnerabilities to "root" devices running older versions of Android. Root status allowed the apps to bypass security protections built into the mobile operating system. As a result, the apps were capable of surreptitiously accessing sensitive data stored, sent, or received by at least a dozen other apps, including Gmail, Hangouts, LinkedIn, and Messenger. The now-ejected apps also collected messages sent and received by Whatsapp, Telegram, and Viber, which all encrypt data in an attempt to make it harder for attackers to intercept messages while in transit.

The apps also contained functions allowing for:

To conceal their surveillance capabilities, the apps posed as utilities for cleaning unwanted files or backing up data. Google said the apps contained evidence they were developed by a cyber arms company called Equus Technologies. In April, Google officials warned of a different family of Android surveillance apps developed by a different provider of intercept tools called NSO Group Technologies. Those apps were related to the advanced iOS spyware known as Pegasus, which was used against a political dissident located in the United Arab Emirates. In that case, however, the Pegasus-related Android apps never made their way into Google Play.

Google has dubbed the new batch of surveillance apps Lipizzan.

Google's disclosure came about 12 hours before researchers from antivirus provider Sophos documented two apps on Google Play that also steal text messages. One app poses as an app store shortcut feature, and the other masquerades as an app for a "Skin Care Magazine." They worked by downloading a plug-in. Together, they had received from 100,000 to 500,000 downloads.
