QuadRooter is a set of four vulnerabilities (CVE-2016-2059, CVE-2016-2503, CVE-2016-2504, CVE-2016-5340, CVE-2016-2060) affecting Android devices built using Qualcomm chipsets. It is estimated that a staggering 900 million Android smartphones and tablets could be affected. Here are 5 ways to protect yourself against this vulnerability.
1. The most important thing you can do is avoid the problem in the first place. Only download apps from known sources. In your Android device’s security settings, make sure you have unchecked “Unknown sources.” This way you will be alerted if you attempt to install an app from a potentially unsafe source.
2. Scan your Android mobile phone with the free Qualcomm QuadRooter Scanner app available from the Google Play store. The app is small (less than 2mb) and takes only a few seconds to run. In addition to the four QuadRooter vulnerabilities, this app also detects the Qualcomm Tether Controller Vulnerability (CVE-2016-2060).
3. Visit your phone manufacturer’s website for any available security patches, especially if you have one of the following highly-vulnerable devices:
- Google Nexus 5X, Nexus 6 and Nexus 6P
- HTC One, HTC M9 and HTC 10
- BlackBerry Priv
- LG G4, LG G5, and LG V10
- New Moto X by Motorola
- OnePlus One, OnePlus 2 and OnePlus 3
- Samsung Galaxy S7 and Samsung S7 Edge
- Sony Xperia Z Ultra
- Blackphone 1 and Blackphone 2
4. Make sure your Android device is running the most up-to-date operating system. That would be either 5.1.1 (Lollipop) or 6.0.1 (Marshmallow) depending on your device.
5. Always have a mobile antivirus app installed on your Android device. Trustlook Antivirus and Mobile Security can be download for free from the Google Play store.
