The 'unpinned' option does nothing, the next 4 use various standard pinning techniques, and the last button uses totally custom code to manually check the certificate. In these kinds of cases, or if you're trying to modify any other kinds of app behaviour, you need to roll up your sleeves and get your hands dirty.įor this article, I've prepped an certificate pinning demo app:Įach button sends an HTTPS request, and validates the connection in a slightly different way. In some cases though apps implement their own custom certificate pinning logic, or do something else unusual, which means the general-purpose script can't recognize and disable the right APIs.

For most apps that do explicitly pin their certificates, you can disable that using this general-purpose Frida script which already knows how to disable all the most popular cert pinning libraries available. For starters, 99% of apps don't use certificate pinning beyond Android's standard restrictions, and for that case if you use HTTP Toolkit on a rooted device you're done in one click. This isn't not easy, but it's usually not necessary. This makes it possible to intercept, inspect & mock all of its traffic in any way we like! Using the tools we're going to talk about in a moment we can take an unknown 3rd party app, find the certificate pinning code within it, and disable that remotely while the app runs on our device. It's not possible to intercept these app's traffic because they won't trust HTTP Toolkit's certificate, even after it's been injected into the device's system certificate store.

(I'm focusing on certificate pinning because it's a common use case and it's convenient, but the techniques here work for all other kinds of reverse engineering & patching too, don't worry!)Ĭertificate pinning is a problem for HTTP Toolkit users, who are trying to intercept HTTPS traffic to see what messages their Android apps are sending & receiving. I'm going to focus on the classic HTTP Toolkit user example here of certificate pinning: where security-conscious apps that send HTTPS traffic go beyond the normal HTTPS validation requirements, and actively check that the HTTPS certificates used are from a small set of specific trusted certificates, not just the standard set trusted by all Android devices. You want to know exactly how a specific bit of behaviour works, and you want to change what it's doing. I'm assuming here that somebody else has written an Android app that you're interested in. In this article, I want to talk you through the core initial steps to look inside any Android app, give you the tools to find & understand the specific code that matters to you, and then show you how you can use that information to modify the app for yourself. There's few good guides to getting started, and even fewer guides on the advanced tricks available. There are some great tools to do this, including JADX & Frida, but using these is complicated, and every reverse engineering problem has its own unique challenges & solutions. Working with Core Data? Working with complex object models? Working with complex delete rules? Working with a lot of data? You want Core Data Editor.I get a lot of emails from users who want to know exactly what their favourite Android app is doing, and want to tweak and change how that works for themselves. The machine class can always be overwritten to match the data model, with humans' work effortlessly preserved' (mogenerator website). Yes, real-world Objective-C code you can really use! Using 'mogenerator' by Jonathan 'Wolf' Rentzsch, Core Data Editor generates 'two classes per entity: one for machines, one for humans. Now that you know about the data model, the data itself and the relationships, you might want to make your coding work more effective? Instead of now manually writing the code, Core Data Editor has a more effective approach: It generates the code for you. Core Data Editor also visualizes binary data to allow you having a look at e.g. Relationships of relationships of relationships - you get the idea.īut that's not all: As the name suggests you can also edit all data - just add or change entries. Need to know relationships? No problem - just double-click any entry and instantly see all relationships of the corresponding entry. Within seconds you have all XML, SQLite or binary data at hand and can analyze it.

Just drop a set of application and a persistent store file on it and let it do its magic.

#CORE DATA EDITOR APP APK MAC#

Core Data Editor makes it easy to analyze Mac and iOS application's data. Core Data Editor is compatible with Mac and iOS applications and supports XML, SQLite and binary stores, visualizes all relationships and is able to edit the data and generate Objective-C code for the data model. Core Data Editor lets you easily view, edit and analyze applications' data (the application has to use Core Data).
