[bug?] Am I a noob or what ?

[maximebories]

Describe the bug I have been successfully using Frida for a few month, but I never had had the chance to have Objection working. Up until recently it was because of a supposed openssl version not supported by libmobileidevice. That was on a MacBook Pro. Right now on Mac mini this is what I'm experiencing:

To Reproduce Steps to reproduce the behavior:

1. pip install frida-tools
2. pip install objection
3. objection --debug --gadget frida-server explore

Similar issues Only one I found with same exact error output

Environment

• Device: iPhone 7 (Global 9,3)
• iOS 14.7.1
• macOS 11.5.2
• Frida 15.0.18
• Frida-server 15.1.1
  • Objection 1.11.0

Please run it again with the --debug flag and paste the output?

[maximebories]

Thank you for your response. I did tried that and there was no difference at all, sorry for not mentioning it. It's not surprising thought, Objection doesn't pass the debug flag and Frida is the first call in the error stack. I will try to force the debug option on the Frida side.

[leonjza]

The debug flag should enable the source map so that we can see where in the agent the crash occurred. Please paste the crash with the flag enabled.

[maximebories]

Exact, I need to put more contrast. Here you go:

[leonjza]

No it's not the same. It now tells us line 8 in environment.ts is to blame, but sadly it seems like the sourcemap is wrong.

my Frida is completely fine, it is the first time I am using objection (and the process I am targeting is running while using the script, same error targeting via pid)

[leonjza]

Sorry for the late reply here!

I just realised that ya'll targeting processes that are not mobile processes. Objection only supports mobile apps at this point in time. If someone is keen, the reason it fails is because these calls on UIDevice won't work on all processes. We could probably rip out the device specific calls and make objection work on any process.

You should rename the issue with the exception we get, so people having the same issue are seing that.

Any update with this ?
