A malicious Android application can be any app that tries to steal private data stored on the device or perform an action unintended by the user.

What’s the risk?Īs seen in the vast majority of software ecosystems, threat actors are constantly uploading malicious pieces of code that try to compromise users as well as other parts of the system. In addition, Android uses the reserved intent-scheme URI intent:// for launching activities that are meant to be browsable. For instance, to play a song in a music player, a link with a custom scheme like mymusicapp:// can be used for opening it. In order to listen for these, an activity must define an intent-filter within its declaration in the Android manifest file. When a public component receives an intent, it can unpack its extras bundle and use the extracted data to launch other components within the app.Īpplications use intents for inter-component and inter-app communication.Īnother way to reach parts in the application is by using deep links - URI-like links that point to an activity within the app. Intents can carry bundled extra arguments of different types, including serialized objects or even other intents. Android Intent vulnerabilities Starting application components In a follow up post, we’ll take a look at finding and fixing them with Snyk Code. In this post, we’ll explore these Andoid Intent-based vulnerabilities to see why and how they work. By analyzing the top applications in 50 categories, Snyk discovered vulnerabilities in various applications including a popular shopping app, a social network app, a client for Reddit and more. This allows triggering injection and redirection attacks resulting in leaking private data stored by the app. Intents are used by internal components to communicate with each other as well as to access exported components of other applications. Our focus was on security issues involving intents - objects used for launching an operation that is to be performed by a component of the app. To do so, we leveraged Snyk Code to analyze and search for vulnerabilities in applications uploaded to the Google Play store.

After discovering and then publishing our findings on SourMint - the malicious iOS ad SDK - the Snyk Security Team decided to dig deeper in the Android ecosystem. Our phones know a lot about us, so it’s important we can trust them.
