[bug] Objection explore freezes

[centrinvest]

Describe the bug Hello! We encountered obscure objection behavior with iOS. At first, the utility worked correctly, the application started up. Then at some point the objection explore command just started to freeze at the "Attempting to attach to process: Gadget" stage.

Tell me what could be the problem?

To Reproduce Steps to reproduce the behavior:

1. I run any application via xcode on the device to get embedded.mobileprovision. At the same time, in the DerivedData folder, I only have one application

2. Run objection patchipa: objection patchipa --source MobileBanking.ipa --codesign-signature 719BFDXXXXXX Using latest Github gadget version: 15.0.6 Remote FridaGadget version is v15.0.6, local is v15.0.4.

5. objection --debug explore [debug] Agent path is: /usr/local/lib/python3.9/site-packages/objection/agent.js [debug] Injecting agent... Using USB device iPhone [debug] Attempting to attach to process: Gadget

And that's it, at this step the objection just freezes and nothing else happens.

Expected behavior objection explore not freezes

Environment (please complete the following information):

• Device: iPhone 7
• OS: iOS 14.4
• Frida Version 14.2.18
• Objection Version 1.11.0

[leonjza]

Can you connect the vanilla frida client?

[centrinvest]

Can you connect the vanilla frida client?

How can i check this?

[centrinvest]

Command frida --usb Gadget also freezes

[leonjza]

Try and use the full bundle identifier of your app instead of Gadget.

[centrinvest]

objection --debug -g "ru.invest.mobilebanking" explore and frida -usb "ru.invest.mobilebanking" also freezes

[leonjza]

Right, you will have to debug this locally. Could be some security feature of the application preventing Frida from working.

[hazcod]

I also have the same issue for a couple of apps. Ideas? explore works as wel as a reconnect but the app is stuck in the splash screen.

[leonjza]

We've run into this internally as well. For now, downgrading frida-server (or gadget by patching with the --gadget-version flag) and local frida python package to latest 14x for now should let you resume normal operation. For 15x support, watch #474.

[hazcod]

Interestingly I am doing this with objection v1.11.0 and Gadget 14.2.18 and the app splash screen stays.

[leonjza]

Right. Only other thing I can suggest now is to check your local frida package version.

❯ pip3 freeze | grep -i frida
frida==14.2.18

[hazcod]

@leonjza hmmmm gotcha, but stays at connecting now:
