In early December, we found a total of 36 apps on Google Play that executed unwanted behavior. These apps posed as useful security tools under the names Security Defender, Security Keeper, Smart Security, Advanced Boost, and more.

The apps were actually able to perform these simple tasks, but they also secretly harvested user data, tracked user location, and aggressively pushed advertisements.Read More
As manufacturers develop Internet of Things (IoT) devices that integrate with widely popular internet-based applications, more and more users see the value in purchasing such devices. Ease of integration becomes an incentive for users to consider adding these products to their network of devices. But while the ease of use can be enticing, these products can also be susceptible to security issues that could introduce far-reaching problems.
To see just how safe and secure IoT devices are and to what extent an attacker can manipulate an IoT device, we tested the built-in security of a particular IoT device type — internet-connected speakers.Read More
Android’s regular security update for December 2017 included a fix for a serious vulnerability that could allow attackers to modify installed apps without affecting their signature. This would allow an attacker to gain access to the affected device (indirectly). First found by researchers in July, this vulnerability (designated as CVE-2017-13156, and also called the Janus vulnerability) affects versions of Android from 5.1.1 to 8.0; approximately 74% of all Android devices have these versions installed.Read More
