Automating Xamarin Protection with Dotfuscator

This week, all eyes of the software community will be fixed on Microsoft's Build conference. Microsoft and its partners are set to announce new technologies and lay out their vision for the future of software development. Recent years have seen the narrative take a decidedly cross-platform approach. Visual Studio Code gives developers tools to create what they want no matter their OS of choice. .NET Core extends the reach of the popular .NET Framework to Mac and Linux. Finally, Xamarin, which was acquired by Microsoft in 2016, lets app developers write their app once, then publish it for Android, iOS, and Windows devices.

As a Visual Studio 2017 Premier Launch Partner, PreEmptive Solutions is pleased to announce, as part of Microsoft Build 2017, a new way to integrate Dotfuscator's protection into Xamarin apps. This new Dotfuscator-Xamarin integration has a number of advantages:

Easy setup - Developers just download an MSBuild targets file and import it into their projects with a few simple property changes. No more need to define custom targets or copy files as a post-build step!
Deep pipeline integration - The new integration automatically puts Dotfuscator into the Xamarin build pipeline, protecting apps as they're built in Visual Studio or MSBuild. Developers don't have to worry about forgetting the protection step, since it's now included as part of the build.
Incremental builds - Don't waste time reapplying Dotfuscator's protection when your project hasn't changed. The integration is smart enough to know when a build is necessary, and when it can be skipped.
Automatic configuration - Get up and running quickly: the integration creates a Dotfuscator config file automatically, with sensible defaults for the project. Instructions are provided for further configuration, including a case study of how to discover which additional identifiers (if any) need to be excluded from renaming obfuscation.
Detailed instructions - We've detailed how to use the integration with a well-known Xamarin.Forms sample. Developers can see the practical application of these instructions through an included git repo, which walks through the process step-by-step.
All major project types supported - The integration supports projects targeting Android, iOS, and Universal Windows (UWP).
Proven protection strategy - The app is protected by Dotfuscator, the industry standard .NET obfuscation and protection tool.
Free to start - The integration works not only with the commercial Dotfuscator Professional Edition, but also with Dotfuscator Community Edition (CE), which is included with Visual Studio. Developers can use the integration to quickly discover the capabilities of Dotfuscator's protection.

To get started, see Integrating Dotfuscator's Protection into Your Xamarin Apps in Visual Studio. There you can read the step-by-step instructions, as well as download the necessary MSBuild targets file.

We plan to keep introducing features like this, to make the protection process easier and more accurate, for Xamarin and all other kinds of apps.

Before I start, I would like to thank PreEmptive for inviting me to write a guest post.

I would like to start my blog with a discussion about the growing cyber threats all over the world. I assume readers are well aware of cyber threats and how they are addressed by people, process, and technology. The continuous planning and advancement of security in the cyber world including but not limited to applications is an interesting read. Here, in my blog, I would like to discuss how companies can support mobile application security for better and safer use of stored data.

On June 11, NIST released Mitigating the Risk of Software Vulnerabilities by Adopting a Secure Software Development Framework. While a solid piece of work in its own right, this document is noteworthy because it stands as one more proof point - in an already long list of proof points, that development processes, the developers themselves, and the organizations they belong to, ALL share some degree of responsibility (liability) for:

Untrusted Environments, Valuable Apps? Put the Protection in the App.

IT environments are evolving. Disappearing are the days of in-house, fixed-endpoint, limited access server stacks — replaced instead by a combination of private and public cloud solutions, mobile applications and IoT devices.

As noted by research firm IDC, public cloud spending now outpaces all other IT infrastructure with a growth rate topping 10 percent year-over-year, while Statista reports that users downloaded more than 178 billion apps in 2017 alone — and are on track to break 250 billion over the next few years.

What does this mean for organizations? That application environments are quickly moving beyond the purview of in-house IT, exposing both apps and network services to steadily growing risk. It creates a paradox: Companies can’t deny the benefits of third-party environments and application partnerships, but also can’t ignore the threat of app and data compromise or reverse-engineering and tampering.

In a recent developer survey, Xamarin.Android developers were 50% less likely to have included rooted device detection or anti-tamper prevention as their Java Android peers were. Yet, both sets of apps are being deployed through the same marketplaces onto the same devices and are governed by the same regulations (PCI, GDPR, HIPAA to name just a few that expect these kinds of controls).

Why are more Xamarin.Android apps going unprotected?

I recently had the opportunity to sit down with Sebastian Holst, PreEmptive’s Chief Strategy Officer, to talk about his most recent trip to Capitol Hill where the topic of the day was copyright protection for small businesses – and for development shops in particular.
