macOS Frida Setup

On an M1 Mac, Frida needs some extra steps to be able to attach to system processes. Mainly writing this down here because it was spread across multiple GitHub issues. Hope it helps some of you who are working with Frida on M1 Macs :)

Versions

macOS Ventura 13.0.1
Frida 16.0.2
Apple M1 Pro

Setup

Disable System Integrity Protection (SIP). Power off Mac, power on with very long press to get the advanced boot options, open the Terminal from the Utilities, enter
# csrutil disable
... and confirm that this bricks your system's security.
Disable some dialogues popping up and asking for permissions, further reducing the security of your system with
# sudo security authorizationdb write system.privilege.taskport allow
... this might be optional but needed if you use Frida via SSH.
Change boot arguments as follows:
sudo nvram boot-args=-arm64e_preview_abi
... and reboot.

Now you should be able to attach to system services, e.g., run:

# frida identityservicesd

Update: macOS 14.4 and higher

Since the introduction of macOS 14.4, there are new mitigations that prevent Frida from attaching to macOS processes, even on SIP disabled systems. Following two tweets from CodeColorist and patch1t, here are further NVRAM arguments that need to be set:

# nvram boot-args="-arm64e_preview_abi amfi_get_out_of_my_way=1 thid_should_crash=0 tss_should_crash=0"

Without these boot arguments, the target process will crash with an error similar to this:

Crashed Thread: 1 frida-helper-main-loop

Exception Type: EXC_GUARD (SIGKILL)

Exception Codes: GUARD_TYPE_MACH_PORT

Exception Codes: 0x0000000000000000, 0x0000000000000000

Termination Reason: Namespace GUARD, Code 2305843030688530432

External Modification Warnings:

Process used task_for_pid().

Debugging

The first two steps are currently also described on the Frida website. Without the adjusted boot arguments, Frida quits with the following error message - apparently on M1 Macs only:

Failed to attach: unexpected error while starting thread (set_thread_state returned '(os/kern) protection failure')

Looking for frida in the Console app, there are three matching messages. The first is the command I ran, the next one is a sandbox error for _frida.abi3.so, and the last one is the one that hints towards the missing boot argument, as it complains about the arm64e preview abi.

Always-on Processor magic: How Find My works while iPhone is powered off

Update: We wrote a paper with even more technical details :) iOS 15.0 introduces a new feature: an iPhone can be located with Find My even while the iPhone is turned "off". How does it work? Is it a security concern? I saw this feature rather early on one of my iPhones with an iOS 15 beta. Here's a screenshot I took in July. The user interface changed a little bit since then. It took a bit longer until the public realized this feature exists. One needs to update to iOS 15.0, use an iPhone that has location services enabled, a logged in user account, participates in the Find My network, etc. And the weirdest thing nobody does these days: One has to turn the iPhone off. But once Twitter found out, this took off. And so did the rumors how this was implemented. Apple's Always-on Processor (AOP) There's only little public documentation about the AOP. All chips and various embedded devices Apple manufactures run a real-time operating system, called RTKitOS. The AOP on

Embedding Frida in iOS TestFlight Apps

Learning reverse engineering on mobile devices can be challenging, especially on iOS, where tooling is less accessible than on Android. On YouTube, I published various videos on reverse engineering with Frida , which is a tool for dynamic reverse engineering of applications during runtime. Last year, I started giving public reversing trainings via BlackHoodie and the university I'm teaching at, along with a training at NULLCON Berlin in March. While starting off with a focus on Android, which can easily be virtualized and rooted, knowledge on iOS reversing is a rare resource that many people want to learn about. But how can we make iOS reversing more accessible to learn, in a world dominated by closed-source tooling and strictly controlled by Apple? Frida can be used on iOS without any jailbreak. Especially when building your own apps, adding it for educational purposes and using it on your own iPhone can be fun. In this blog post, we'll look into two options: (1) Distributin

BlueZ: Linux Bluetooth Stack Overview

Found some time for another Bluetooth rant :) This time it's going to be about BlueZ , the Linux Bluetooth stack. Note that there are other Bluetooth stacks for Linux such as BTstack , but I didn't find the time to play around with these, and BlueZ is still what you get these days if you install a normal Linux distribution. This is my view on about BlueZ and a couple of things might be over-simplified. Feel free to add comments to this post if anything is wrong or is better explained elsewhere. However, I found that there is no good overview from a programming and hacking perspective, and often times I get questions about patching certain things within InternalBlue that have a root cause deep down in the Linux kernel. BlueZ is missing documentation. In fact, I ended up using dynamic debugging here and there to understand which functions are still called and which are deprecated. Otherwise, this blog post would not be needed for an open-source project m) Linux Bluetooth stack vs
