Android is an open-source mobile device operating system that was created by Google.
Today, Android is one of the most used mobile operating systems. Because of this, hackers often create malware for Android because of its larger market share. Viruses on Android are usually fake programs on Google Play. Android also has some ransomware viruses, but these function very differently than ransomware on PCs. The malware is usually wiped by Google shortly after the discovery. Because of Androids operating system, and ease of use. It's very easy to create fake apps as Android allows users to download programs with little to no security or authenticity check. Unlike IOS apps can be developed and put on the play store for free and without in-depth security checks. While IOS requires a full malware check and a 100$ fee before posting, this fee and security check makes it expensive and incredibly difficult to post infected apps in the app store. Android also allows you to give administrative permissions to apps. This means that infected apps can gain permission to everything on the phone, including external hardware. Below is a list of some administrative permissions that are granted.
- Using microphones, cameras and internal monitors such as gyroscopes, accelerometers, and GPS.
- Controlling screen and overwriting app displays (App overlay)
- Grabbing system information such as Wifi, Bluetooth, Operating system information and CPU or graphics usage.
The latest version of Android is 8.0 Oreo, which was released in 2017.
