It includes an example of insecure broadcast dispatch:Īnd the interception of implicit intents when an activity is launched:ĭo you want to check your mobile apps for such types of vulnerabilities? Oversecured mobile apps scanner provides an automatic solution that helps to detect vulnerabilities in Android and iOS mobile apps. These vulnerabilities are examined in our vulnerable Android app OVAA. We have created special categories such as Insecure activity start, Using an implicit intent to send a broadcast, Starting a service with an unspecified component and so on. Oversecured automatically locates vulnerabilities of all these types and displays the places where these intents are created and run in the scan report. Insecure (implicit) intents look just the same: the only difference is the methods to which they are passed ( startActivity, sendBroadcast, startService etc.). If the intent contains any private data, then data can be leaked to third-party apps installed on the same device when implicit intents are used. action, data, mime type, categories) and Android itself decides which component to call. With implicit intents, only certain parameters are set (e.g. Explicit intents have a set receiver (the name of an app package and the class name of a handler component) and can be delivered only to a predetermined component (activity, receiver, service). All intents on Android are divided into two big categories: explicit and implicit.
