As if having your Windows computer files and iPhone being held for ransom wasn’t bad enough, Android-based devices can now “enjoy” that ignominious fate as well. Security researchers are reporting that hundreds of Android devices, primarily in Russia and the Ukraine are being infected by a Trojan called “Pletor” which can do just like it’s Windows based counterparts: the victims were tricked into installing the trojan by fake websites, apps and games, and once the victim’s content is encrypted, the trojan demands a ransom of approximately $30-35 USD to unlock the data.
What this means for you:
Though it has happened before, it’s still extremely rare for a Trojan like the above to make it through the screening process that Google performs on all the apps that are available through the Google Play store, and even if one does, it’s pulled quickly. Google can even reach out retroactively to affected phones to remove the harmful app. That being said, it’s not hard to “side-load” apps on Android devices, which is primarily the way Android malware spreads. The easiest way to keep your Android devices safe: don’t side-load apps. Only install apps published through Google’s Play Store. Keep in mind, for everything not a Kindle Fire, installing apps from Amazon’s App Store is considered side-loading, and should only be done if you really know what you are doing. And if you just can’t live without side-loading apps, make sure you don’t store any important information on your device, and keep it well away from sensitive business data. The more risky your activities are on the device, the more likely it is that device will get compromised.
