Suppress Application Icon
A malicious application could suppress its icon from being displayed to the user in the application launcher to hide the fact that it is installed, and to make it more difficult for the user to uninstall the application. Hiding the application's icon programmatically does not require any special permissions.
This behavior has been seen in the BankBot/Spy Banker family of malware.[1][2][3]
Procedure Examples
Name | Description |
---|---|
Agent Smith |
Agent Smith can hide its icon from the application launcher.[4] |
Cerberus |
Cerberus hides its icon from the application drawer after being launched for the first time.[5] |
Desert Scorpion |
Desert Scorpion can hide its icon.[6] |
FakeSpy |
FakeSpy can hide its icon if it detects that it is being run on an emulator.[7] |
FlexiSpy |
FlexiSpy is capable of hiding SuperSU's icon if it is installed and visible.[8] FlexiSpy can also hide its own icon to make detection and the uninstallation process more difficult.[9] |
Ginp | |
Gustuff | |
Mandrake | |
Rotexy | |
SimBad | |
Twitoor | |
ViceLeaker |
ViceLeaker includes code to hide its icon, but the function does not appear to be called in an analyzed version of the software.[16] |
Mitigations
This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.
Detection
The user can examine the list of all installed applications, including those with a suppressed icon, in the device settings.
