Security Auditor on Android TV

Dr.Web performs diagnostics and analysis of the security of your device and helps resolving the detected problems and vulnerabilities using the Security Auditor component. This component is enabled automatically when the application is launched for the first time and after registering the license.

Resolving security problems

To review the list of the detected problems and vulnerabilities (see Figure 36), select the Security Auditor section on the application main screen.

Figure 36. List of security problems detected on your device

Dr.Web detects the following categories of security problems: applications with highest priority of SMS processing, hidden device administrators, vulnerabilities and system settings that affect the device security. To view the detailed information on any detected problem and to resolve it, open one of the categories and tap a problem in the list.

System settings

USB debugging and installing applications from unknown sources are the system settings that can affect the security of the device. It is insecure to use conflicting software as well:

•USB debugging is intended for developers and allows copying data from PC to the device and vice versa, installing the applications on the device, viewing their logs and deleting them in some cases. If you are not a developer and do not use the debug mode, you are recommended to turn this mode off. To open the corresponding device settings section, tap Settings on the screen with detailed information on the problem.

•Installing application from unknown sources is one of the main reasons devices running Android get infected. Applications downloaded from elsewhere other than the official market (Google Play) are likely to be unsafe and become a threat to device security. To mitigate risks of installing the unsafe applications, you are recommended to disable application installation from unknown sources. To open the corresponding device settings section, tap Settings on the screen with detailed information on the problem. You should also scan for viruses all the applications you install on your device. Before scanning, make sure Dr.Web virus databases are up to date.

•Software conflicts. Using conflicting software.

•Dr.Web notifications are blocked. When notifications are blocked, Dr.Web cannot immediately inform you on detected threats. This compromises security of your device. That is why, you are recommended to enable Dr.Web notifications in the settings of your device.

Vulnerabilities

Vulnerability is a weakness in the source code which allows cybercriminals to impair the correct operation of a system.

Dr.Web detects the following vulnerabilities in the system: BlueBorne, Master Key (#8219321), Extra Field (#9695860), Name Length Field (#9950697), Fake ID (#13678484), ObjectInputStream Serialization (CVE-2014-7911), PendingIntent (CVE-2014-8609), Android Installer Hijacking, OpenSSLX509Certificate (CVE-2015-3825), Stagefright and Stagefright 2.0, SIM Toolkit (CVE-2015-3843). They allow adding malicious code to some applications, that may result in acquisition of dangerous functions by these applications and damage the device. Dr.Web also detects the Heartbleed vulnerability — an error in OpenSSL, that can be used by cybercriminals to access user confidential information.

If one or more of these vulnerabilities are detected on your device, check for operating system updates on the official website of your device manufacturer. Recent versions may have these vulnerabilities fixed. If the updates are not available, install applications only from trusted sources.

User certificates

If any user certificates are detected on your device, Security Auditor detects and displays them. Certificates may be used by a third party to monitor your network activity. If you are not aware why these certificates are installed on your device, you are recommended to remove them.

Applications exploiting Fake ID vulnerability

If applications exploiting Fake ID vulnerability have been detected on the device, they will be displayed in the separate Security Auditor category. These applications can be malicious, therefore it is recommended to delete them. To delete the application, tap Delete on the screen with the detailed information on the problem related to this application, or use standard OS tools.

Root access

The device may become vulnerable to different types of threats if it is rooted, i.e. the procedure of rooting has been performed to attain control (known as "root access") over the device system. It results in ability to modify and delete system files, that may potentially damage the device. If you rooted your device yourself, rollback the changes for security reasons. If root access is the integral feature of your device or you need it for your everyday tasks, be extremely cautious installing applications from the unknown sources.
