Dump appears to be successful, IDA complains

[mariopepe]

General information:

• iOS version: 12.1
• Command used: example: clutch -d

What happens:

I successfully dumped an ipa file through Clutch on iOS 12.1, it goes onto /var/tmp/ , I copy it on my mac, I open the binary file with IDA but still get this message: "The file is iOS-encrypted. Its disassembly will likely be useless. Do you still want to continue?"

Why does this happen? Thanks a lot

App Info:

• Price: Free (no in-app purchase)
• I feel like (95% sure) it is made through Google Flutter, it contains more than 10 executables (of course it is also available for Android).

I can't test this but whoever does is going to need to know the app name, version, bundle ID, etc.

@Tatsh I updated the issue with the requested information, sorry, if something is still missing I will add it.

To be honest i think that even if you would try it on another iOS version, it would still be relevant. Maybe is an app specifica problem. I'm not a pro user, but the app structure looks very "unusual": there are at least 10 different executables (like facebook sdk, crypto, audioplayer, etc...), maybe it is just the way Google Flutter app are done...

To be honest i'm checking and checking again the clutch process and probably it was not successful. I'm not a PRO user enough to be certain about that, if you agree I would close this issue because maybe there are problems with iOS 12 and not the app
