This is the meta repository for Project ARTist that, e.g., captures issues that concern more than one of the projects or other matters related to ARTist but not part of any repository (such as the website). For more information about the overall ARTist project, check out the dedicated section on this topic below.
Whenever you encounter an issue, such as a bug or a feature request, that does not clearly fit into a single repository of the ARTist project, chances are high you should put it here. If in doubt, ask at our Gitter chat.
ARTist is a flexible open source instrumentation framework for Android's apps and Java middleware. It is based on the Android Runtime’s (ART) compiler and modifies code during on-device compilation. In contrast to existing instrumentation frameworks, it preserves the application's original signature and operates on the instruction level.
ARTist can be deployed in two different ways: First, as a regular application using our ArtistGui project that allows for non-invasive app instrumentation on rooted devices, or second, as a system compiler for custom ROMs where it can additionally instrument the system server (Package Manager Service, Activity Manager Service, ...) and the Android framework classes (boot.oat). It supports Android versions after (and including) Marshmallow 6.0.
For detailed tutorials and more in-depth information on the ARTist ecosystem, have a look at our official documentation and join our Gitter chat.
We are about to enter the beta phase soon, which will bring a lot of changes to the whole ARTist ecosystem, including a dedicated ARTist SDK for simplified Module development, a semantic versioning-inspired release and versioning scheme, an improved and updated version of our online documentation, great new Modules, and a lot more improvements. However, in particular during the transition phase, some information like the one in the repositories' README.md files and the documentation at https://artist.cispa.saarland might be slightly out of sync. We apologize for the inconvenience and happily take feedback at Gitter. To keep up with the current progress, keep an eye on the beta milestones of the Project: ARTist repositories and check for new blog posts at https://artist.cispa.saarland .
We hope to create an active community of developers, researchers and users around Project ARTist and hence are happy about contributions and feedback of any kind. There are plenty of ways to get involved and help the project, such as testing and writing Modules, providing feedback on which functionality is key or missing, reporting bugs and other issues, or in general talk about your experiences. The team is actively monitoring Gitter and of course the repositories, and we are happy to get in touch and discuss. We do not have a full-fledged contribution guide, yet, but it will follow soon (see beta announcement above).
ARTist is based on a paper called ARTist - The Android Runtime Instrumentation and Security Toolkit, published at the 2nd IEEE European Symposium on Security and Privacy (EuroS&P'17). The full paper is available here. If you are citing ARTist in your research, please use the following bibliography entry:

There is a follow-up paper where we utilized ARTist to cut out advertisement libraries from third-party applications, move the library to a dedicated app (own security principal) and reconnect both using a custom Binder IPC protocol, all while preserving visual fidelity by displaying the remote advertisements as floating views on top of the now ad-cleaned application. The full paper The ART of App Compartmentalization: Compiler-based Library Privilege Separation on Stock Android, as it was published at the 2017 ACM SIGSAC Conference on Computer and Communications Security (CCS'17), is available here.
