Objection
OpenSSL, Certpinning and Memory patching. Sounds fun right?
This blogpost will cover the research I presented at BSides JoBurg. You can watch the talk on YouTube, and code can be found on our GitHub page. This journey started after having looked at some certificate-pinned apps. The majority of apps that appear to implement cert pinning, don’t actually have cert pinning but rather just use a custom trust manager or are not proxy aware (this also applies to things…
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…

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…
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. 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…
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…
