Objection
Android Application Testing Using Windows 11 and Windows Subsystem for Android
With the release of windows 11, Microsoft announced the Windows Subsystem for Android or WSA. This following their previous release, Windows Subsystem for Linux or WSL. These enable you to run a virtual Linux or Android environment directly on your Windows Operating System, without the prerequisite compatibility layer provided by third-party software. In this post I’ll show you how to use WSA for Android mobile application pentesting, such that you can perform all of the usual steps using only Windows, with no physical Android device or emulator needed.
on ios binary protections
I just got off a call with a client, and realised we need to think about how we report binary protections a bit more. More specifically the ios info binary command in objection. They can be a pain to explain if not well understood, and even harder to remediate! Binary protections make exploitation attempts much harder so, naturally we want all of them on. However, as you’d see in this article, not everything can always be enabled and sometimes it’s hard to understand why.
Android Application Specific Proxies, Easy Mode
In this post I want to share two things. First, a quick primer on how you would you go about navigating the source code when contributing to objection, and secondly an application specific proxy feature I added to it. Introduction While on holiday I wanted to look into a certain mobile application that dealt with medical information. I was mostly interested in the data that was sent and received by the application so this meant proxying the traffic into Burp. I did not have a test device with me, so I had to use my personal device. This being my personal device meant that once I had the proxy set, certain applications would cease to function normally (especially those with SSL pinning) as Burp was in the middle.
mettle your ios with frida
For a long time I have wondered about getting Meterpreter running on an iOS device using Frida. It wasn’t until I had a Twitter conversation with @timwr that I was reminded of Mettle. It was finally time to give it a try. I built an objection plugin that would load it for you, which you can find here. My talk at DEF CON 27 mainly covered some ideas on how we could interact with live object instances in interesting ways. However, there were also some examples of how we could use Frida’s Module.load() API to side load existing external tooling that come in the form of shared libraries (either by default or wrapping them ourselves). With Mettle targeting low-resource or embedded devices, its native code approach meant it also supported iOS. So if we could get a compiled Mettle dylib, we could load it with Frida. You don’t need Frida to load a dylib of course. Using something like insert_dylib would work just as well. The nice thing about using something like Frida though is that we have some external control over the loading process and any post processing that we may need.
