preemptive / ppios-rename Goto Github PK

Hi,
This is not an issue, but a question.
While I understand that you do not support lower than iOS9, I'm curious as to whether you know of any incompatibilities with iOS8. Are the expected related incompatibilities related to XIB, storyboards etc. Or is it something else?

My Objective C project uses a cocoapod written in swift, and I'm getting the next error:
Error: PPiOS-Rename cannot process apps containing Swift code
I know that PPiOS-Rename doesn't support Swift, but is there a way to filter swift files? Thanks.

Hello Nathan, I'm starting to use PPIOS-Rename according to you, but I'm facing some problems.
I run the commands: "ppios-rename --analyze -x IgnoredSymbol -F !ExcludedClass -F !FBS* -F !FIR* -F !ModalSMSCredito* -F !GAI* -F !GGL* -F !Branch* /Desktop/Projetos/IOS/appPontoCerto//DerivedData/Build/Products/Debug-iphoneos/XXXXX.app" and "ppios-rename --obfuscate-sources".
But when I build my project, I get a lot of mistakes in relation to the 'FBSDK'(Facebook), 'FIRA'(Firebase), in my class 'ModalSMSCredito' and so on.
It is as if all the options "-F !YYY*" were ignored, and all were included in the obfuscation.

I have this when loading a new view controller:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView (<UITableView: 0x7fb7b318a000; frame = (0 0; 375 812); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x604000a4d5c0>; layer = <CALayer: 0x604000829c40>; contentOffset: {0, -88}; contentSize: {375, 132}; adjustedContentInset: {88, 0, 34, 0}>) failed to obtain a cell from its dataSource (<_UIFilteredDataSource: 0x604000a4d0e0>)'

Tried and solved some with #3 but still having this in many parts of the code. Any solution?

Dear master
I have an idea, if you can make PPIOS Obfuscation direct with binary files, we don't care about back to origin code anymore, how can do that??

Thanks

Hello,

Im trying to use this repository to obfuscate my objective C source code for an ionic application.

I have installed the .exe and have added to the usr/local/bin.

Im preforming the following command:

ppios-rename --analyze /path/to/program.app/program but I'm not sure what the path should be.

I tried to use the path where the ios generated project is located, but I keep getting:

Input file does not contain an executable

Example of the command:

ppios-rename --analyze /location/platforms/ios

After merge this change , i can get the class but i can not dump the small method name and types .

debug info : in CDObjectiveC2Processor.m , when i try to get a class instance method ,
objc2Method.name = [cursor readPtr:small];
objc2Method.types = [cursor readPtr:small];
objc2Method.imp = [cursor readPtr:small];
NSString *name = [self.machOFile stringAtAddress:objc2Method.name];
NSString *types = [self.machOFile stringAtAddress:objc2Method.types];
i got a nil value . All the instance method is this . It look like the offset or mask did not right .

Seems that all constrains are somehow being mixed up on the obfuscated code. This is include programmed constrains and constrains that are on the xib files. Is there any solution for that?

I'm trying to obfuscate the main app and watch executables, but after that symbols.h file contains the following:

#ifndef DOUBLE_OBFUSCATION_GUARD_PPIOS
#define DOUBLE_OBFUSCATION_GUARD_PPIOS
#else
#error Double obfuscation detected. This will result in an unobfuscated binary. Please see the documentation for details.
#endif

Is there a way to also obfuscate the watch target, or it is not yet supported?

I have used Xcode run script method to obfuscate the Objective-c code on Xcode 8.3.3. Project can be build. But the app crashes upon launch due to story board key value coding-compliant.

Unknown class s3YfbbAX in Interface Builder file

I am getting 5 Unknown class xxxxxxx in Interface Builder file errors. All those 5 are not external libraries which provide Interface Builder files.
Instead those 5 are the root view controllers (TabbarController and 4 UIViewControllers).

Problem is, I cannot find s3YfbbAX in the symbols.h file. I can see this key in the story board. But, in symbols.h has a different key for the equivalent Class name.

Please advice me on this

Hi,
I have an application Unity that uses the iOS static library. Then this application Unity is build in XCode.
I carefully read your documentation "Obfuscate Static Libraries", but at the time of building, the iOS static library are already "hidden in the root" of the Unity app, and XCode cannot obfuscate this. Maybe you can suggest a workaround or another tool? I'll be very grateful.

happens in the analyze phaze, terminal log this:

ppios-rename[14271:115927] Error: Cannot find offset for address 0x700000000100a617 in stringAtAddress:

Recently ppios stopped working and it's throwing dozens of unknown errors on dataOffsetForAddress.
My project didn't change at all, this happened over night, after I updated to MacOS 12.6 and Xcode 14.0.1

All missing commands are related to 0x80000034 and 0x80000033

This should not be Swift related because I don't use any Swift code.

Any ideas? Thanks in advance

Side note: the same project/file works fine when I switch to a MacOS 12.3 / XCode 13.1 Macbbok

Just wanted to know is it possible to obfuscate just framework? Because when I do analyze my framework it returns empty symbol.map file. Best regards

Hi,

I followed the instructions to use PPiOS-Rename in order to obfuscate the source code of my iOS App. As per the instructions mentioned in the guide, I created two additional targets Build and analyze and Apply Renaming. I followed the below steps:

1- Build using Build and analyze target
2- Build using Apply Renaming target
3-Finally build using the original target

All 3 were build successfully without any errors. However when I run the application on the simulator after the step 3 above, I get the following error for my view controller:

Terminating app due to uncaught exception 'NSUnknownKeyException'
[<StartupViewController 0x7fb5a6515510> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key y4feaiGk

Upon inspecting the y4feaiGk, its assigned to a UIButton in the corresponding xib file.
If i exclude the above view controller, the error comes up in the next ViewController.

I will appreciate any help as I am unsure what is going wrong over here. Thanks a lot!

Is the source code for the static library necessary if I want to confuse symbols in the static library?

No visible @interface for 'UIViewController' declares the selector 'a5srnjH7'

//in symbols.h
#ifndef viewDidLoad
#define viewDidLoad a5srnjH7
#endif // viewDidLoad

why not exclude system framework method?

Im having an issue while building the scheme "Build and Analyze ".

Hi everyone,

I'm facing this error message. Can you help me to solve it?

error: no visible @interface for 'MyManager' declares the selector 'setC1OpVkNd:'
[[MyManager sharedInstance] setPublicKey: pulicKey];

Apple would reject an app using this library straight forward for that reason:

From Apple 2. 3 Performance: Accurate Metadata Guideline 2.3.1 - Performance

We discovered that your app contains hidden features. Specifically, It would be appropriate to remove all code obfuscation and selector mangling from this app before resubmitting for review.

The next submission of this app may require a longer review time.

Next Steps

    Review the Performance section of the App Store Review Guidelines.
    Ensure your app is compliant with all sections of the App Store Review Guidelines and the Terms & Conditions of the Apple Developer Program.
    Once your app is fully compliant, resubmit your app for review.

If you believe your app is compliant with the App Store Review Guidelines, you may submit an appeal. Alternatively, you may provide additional details about your app by replying directly to this message.

I thought of replacing the random numbers on symbols.map file into some dictionary words. And then run the obfuscation code (using the new created symbols).

What I wanted to know is if the obfuscation process change anything further then those names to random number that could look "strange" on the binary? What I mean is that if instead of random numbers I would use some English words would the binary have anything else that would point that the app uses obfuscation?

I use the PPIOS-Rename framework. I'm doing everything right on the description, but why does not it obfuscate my methods and classes? What could be the reason?

I followed the trouble shooting steps and auto generated my own pch file, I named the file accordingly yet I still get the error “Couldn’t find any *-Prefix.pch files under .” - what am I doing wrong? I followed all the instructions and i have configured my build settings to us the pch file as well.

I understand there is an issue about this issue #6 , but my situation is quite different.

I have used Xcode run script method to obfuscate the Objective-c code on Xcode 10.1. Project can be build. But the app crashes upon launch due to xib file key value coding-compliant.

Unknown class v7aeUe4E in Interface Builder file

this class is a UIView subclass, and the v7aeUe4E DO EXISTS in the symbol.h with corrent class name

Please advice me on this. Thanks a lot, it costed me 4 hours and didn't find any solution.

Confuse the class, but the xib name is still not confused before the class name and xib name is inconsistent, resulting in Viewcontroller load can not find Viewcontroller.xib, how to solve this problem?

In the method -[CDSymbolMapper writeSymbolsFromSymbolsVisitor:toFile:], you invert the symbols dict before writing it to symbols.map, and then invert it again after reading from the symbols.map. I am wendering about this.

I'm looking for the ControlFlow utility mentioned in your README.md, although came up empty locating it.

It is possible to reverse the process of obfuscation in dSYMs by using a utility included with PPiOS-ControlFlow. 

Where can I obtain this tool? Thank you.

Please I ma getting this errror recently while using Xcode 14.2 while building Build_And_Analyse
My project is pure objective c.

Your help is really appreciated.

如果你的APP打算发布到App Store，切勿用代码混淆。 会被无情驳回且延期审核/(ㄒoㄒ)/~~
If your APP is going to be published to the APP Store, don't confuse code. It will be ruthlessly rejected and delayed.

I am using Xcode 13.2.1

I had created one demo project for integrating code obfuscation, but facing above issue.
My app name is : COTest

I performed below steps:-

STEP- 1) ppios-rename --analyze --symbols-map /Users/Justmac/Desktop/TEMP/symbols.map /Users/Justmac/Library/Developer/Xcode/DerivedData/COTest-bsavpegzjpcdskanvimkgayjsktr/Build/Products/Debug-iphonesimulator/COTest.app

After performing this step the symbols.map file had been successfully created in TEMP folder.

STEP 2) ppios-rename --obfuscate-sources --symbols-map /Users/Justmac/Desktop/TEMP/symbols.map.

After this step storyboard outlets & action get renamed(only on storyboard) & generated the symbols.h file & showing error in that file.

I am trying to obfuscate my code which includes dynamic framework.
I don't want to exclude the framework because then the binary contains unobfuscated functions from the framework.
Is there a way to do it?

I tried to obfuscate my code with my linked framework and I got the error: Use of undeclared identifier {framwork}
I tried to obfuscate my code with my linked framewor, which was already obfuscated (added the symbols.h file to the *.pch file ) and I got the error:Undefined symbol: OBJC_CLASS$_{framwork}

I ran out of ideas, can you help me?

When works in Xcode 9 and Swift ?

Hi,
Please I have an XCFramework and I am using PPIOS for obfuscation,
I execute the following instructions to do that:
a-ppios-rename --analyze --framework ProjectName /path/to/framework/executable
b-ppios-rename --obfuscate-sources
I successfully create symbol.map and symbols .h but the clients are still able to access and read all functions , how can I build this framework before drop it inside another project.?

Or in another way , if I have an Xcode project created as framework , I obfuscate this project as you mentioned how can I generate now the xcframework from this obfuscated code?

The obfuscation should be done before or after creating the xcframework?

Your help is really appreciated.

Regards

Hi, I am very interested in this tool, but I am not able to figure out how to make the obfuscation work and be able to see the code without obfuscation in the Crashlytics error traces.

Is this possible?

Thanks you very much # #

Hi,
I've an objective-c project that use several pods. Some of that pods are written in swift.

I've understood that swift code is not supported, so I've tried to include swift pods as compiled .frameworks (so NO swift code, but compiled binaries), but I obtain the same error "PPiOS-Rename cannot process apps containing Swift code".

As you know objective-c is dying, and any modern project use dependencies
which will increasingly be in swift.

Any idea how to bypass the restriction? Maybe an exclude feature, or a bridge header, or something?

Thanks for your precious support.

This isn't so much a bug but a question. How will this tool handle a hybrid Obj-c/Swift application? Can swift code be obfuscated as well? If not is it just ignored by default, or would I need to manually setup an ignore file of sorts?

Thanks in advance for your time

Have used PPiOS-Rename for my project and observed double obfuscation detected. To fix this issue, the documentation says that make sure that source tree is always reset to an unmodified state. Could you please explain in detail, what is that need to be taken care here.

Does this work with Swift 3?

Hi,
I followed all the steps as mentioned but at the end of all the steps i got the following error.

Hello,
I did obfuscate my project using the correct steps and everything worked till I found this crash.
ppios-rename version: v1.2.0

2018-04-18 11:43:15.905099+0300 XXXX[1907:388059] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<k5kGGmHJ 0x17ad4fc0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key XXXX.'

I believe my class does not recognize my property after obfuscation.
How should I fix this crash ?

Thank you!
