Android/Adware.MobiDash is the detection name for adware that targets mobile devices running the Android OS. It comes in the form of an Ad SDK that can be easily added onto any APK.
Many times, a legitimate APK is taken and repackaged with Ad SDKs. MobiDash displays pop-up ads after the screen is unlocked.
A unique characteristic of MobiDash is that it waits roughly three days after being installed to display ads. MobiDash became prevalent in 2015, and continues to be spread via hundreds of variants.
Android/Adware.MobiDash infected apps are mostly distributed through third-party app stores.
Infected devices will display ads until uninstalled. Unless users fall victim to downloading and installing other apps by clicking on the ads, there is no further harm done other than the annoyance of ads being displayed.
Malwarebytes for Android protects against Android/Adware.MobiDash.
These apps can be uninstalled using the mobile devices uninstall functionality. The tricky part is identifying the offending behavior and app. That is where Malwarebytes for Android can help by identifying these apps and removing them.
