The distribution contains an eclipse workspace with all source-code projects as well as readily compiled APKs.

DroidBench was created by Christian Fritz, Steven Arzt and Siegfried Rasthofer of the EC SPRIDE Secure Software Engineering Group.

You are most welcome to contribute additional test cases to DroidBench. To do so, please fork the project, commit an appropriate Eclipse source project and APK, update this README and then send us a pull request.

Version 1.2 comprises the following 64 test cases:

• ArrayAccess1: Stores both a tainted and an untainted value in an array and then leaks the untainted one. Array indices are constants.
• ArrayAccess2: Stores both a tainted and an untainted value in an array and then leaks the untainted one. Array indices are calculated.
• HashMapAccess1: Stores both a tainted and an untainted value in a hash map and then leaks the untainted one. Map keys are constants.
• ListAccess1: Both a tainted and an untainted value are stored in a list. Only the untainted value is leaked.

• AnonymousClass1: Registers a callback handler for location updates in an anonymous inner class and leaks the incoming location data inside the callback.
• Button1: The sink is called after the user clicks a button. The button handler is defined via XML.
• Button2: Only clicking buttons in a specific order leads to a data leak.
• Button3: A new callback is registered in another callback's handler. The second handler leaks the data obtained by the first handler.
• Button4: The sink is called after the user clicks a button. The button handler is defined via XML using an include directive.
• LocationLeak1: Registers a listener for location updates, stores the value and leaks it later in the lifecycle.
• LocationLeak2: Similar to LocationLeak1, but the activity class directly implements the callback interface.
• LocationLeak3: Similar to LocationLeak1, but the callback handler is in a dedicated class decoupled from the activity using an interface.
• MethodOverride1: Overwrites an internal Android method to hide a leak.
• MultiHandlers1: Contains two activities and two handlers that do not leak any data if the correct activity is used with the correct handler.
• Ordering1: Leaks variable contents before the handler initializing them is even registered.
• RegisterGlobal1: Both source and sink are part of a global (application-level) lifecycle handler.
• Unregister1: Registers and directly unregisters a callback before it can be invoked. The code in the callback can thus never leak any data.

• FieldSensitivity1: Both tainted and untainted data is stored in a data object; the untainted value is leaked.
• FieldSensitivity2: Similar to FieldSensitivity1, but source and sink calls are distributed across the lifecycle.
• FieldSensitivity3: Both tainted and untainted data is stored in a data object; the tainted value is leaked. Source and sink calls are distributed across the lifecycle.
• FieldSensitivity4: Field contents are sent before tainting the field.
• InheritedObjects1: Chooses an object's actual type based on a conditional. Only one possible type leads to a leak.
• ObjectSensitivity1: Writes a tainted value into an object and an untainted one into another object of the same type. Leaks the untainted value.
• ObjectSensitivity2: Writes a tainted value into a field and then overwrites it with untainted data.

• IntentSink1: A tainted value is leaked to another application using an intent.
• IntentSink2: Similar to IntentSink, but the value is sent out in a callback method defined in XML.
• ActivityCommunication1: Contains two activities that communicate using static fields.
• IntentSource1: Two tainted leaks: the first one is that a tainted value is leaked to another app using an intent by startActivityForResult. The other one is that onActivityResult method gets intent as tainted data and then logs it.

• ActivityLifecycle1: Calls to sources and sinks distributed across an activity lifecycle.
• ActivityLifecycle2: Activity class inherited from a superclass containing the lifecycle method which leaks the tainted value.
• ActivityLifecycle3: Calls to sources and sinks distributed across instance state handling methods.
• ActivityLifecycle4: A tainted value is obtained on onPause() and leaked when the activity is restarted later.
• ApplicationLifecycle1: Obtains a secret value when the application is launched and sends it out in the onResume() method of the main activity.
• ApplicationLifecycle2: Obtains a secret value when the application is launched and sends it out in the low memory callback of the application.
• ApplicationLifecycle3: Obtains a secret value when a content provider is initialized and leaks it in the onCreate() method of the application.
• BroadcastReceiverLifecycle1: Calls to sources and sinks distributed across a broadcast receiver lifecycle.
• FragmentLifecycle1: Calls to sources and sinks distributed across a fragment lifecycle.
• ServiceLifecycle1: Calls to sources and sinks distributed across a service lifecycle.

• Exceptions1: Saves a tainted value into a local variable, raises an exception and sends the value out in the exception handler.
• Exceptions2: Saves a tainted value into a local variable, implicitly raises an exception (ArrayIndexOutOfBounds) and sends the data out in the exception handler.
• Exceptions3: Saves a tainted value into a local variable, but the exception handler which would send it out is never invoked.
• Exceptions4: Throws and exception containing a tainted value and sends it out in the exception handler.
• Loop1: Contains a simple loop and a data leak.
• Loop2: Retrieves location information through a callback and leaks it via nested loops.
• SourceCodeSpecific1: Uses unusual code construct a = p ? b : c.
• StaticInitialization1: Passes a tainted value into a static initialization method.
• StaticInitialization2: Sensitive data is obtained during static initialization of a class and leaked in non-static code
• UnreachableCode: Passes tainted data into a method that is never called.

• DirectLeak1: The device id is read out and sent via SMS on the activity's onCreate() event.
• InactiveActivity: Data leak in a disabled activity.
• LogNoLeak: Writes untainted data into a log file.
• Obfuscation1: This APK contains an own implementation of android.telephony.TelephonyManager. However, on a real device the preloaded OS implementation will always hide the custom one and you will always get a real IMEI. Testes on Galaxy Nexus 4, no guarantees for the emulator, though.
• Library1: not a test case on its own, part of Library2.
• Library2: The IMEI is read out inside a custom library and then leaked in the app.
• PrivateDataLeak1: Summary test case containing various challenges.
• PrivateDataLeak2: Leaks a value from a password field.
• PrivateDataLeak3: The IMEI is written into a file, read out again and then leaked.

• ImplicitFlow1-4: Test cases for implicit flows.

• Reflection1: Sensitive data is stored in a field of a reflective class and directly read out again and leaked.
• Reflection2: Sensitive data is stored in a field of a reflective class, read out again using a method implemented in the "unknown" class and leaked.
• Reflection3: Sensitive data is stored using a setter in a reflective class, read back using a getter and then leaked. No type information on the target class is used.
• Reflection4: Sensitive data is read using a function in a reflective class and leaked using another function in the same reflective class.
