Download a cracked ipa. (eg. https://www.iphonecake.com) 11 | 2. Use Xcode to create an iOS Dynamic Framework (see below as an example). Build the framework target for iphoneos (non-iphonesimulator) 12 | 3. Reveal the framework in finder and locate the dynamic library binary. 13 | 4. Copy the dynamic library binary file and any depedent dylibs into a folder (lets call it DYLIBS). You may need additional XCode stock swift dylib which you can find them at ```/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift```. Copy any required swift dylib into the DYLIBS folder 14 | 5. Go to the root level of this repository and run ```sh ./patchapp.sh cracked.ipa ./DYLIBS``` 15 | 6. You will see an output file called "cracked-patch.ipa". Use Cydia Impactor (http://www.cydiaimpactor.com) to sign the new and install it into your device. 16 | 17 | #### This repository was inspired by the work of https://github.com/bamtan/PokemonGoAnywhere 18 | 19 | -------------------------------------------------------------------------------- /iReSign/iReSign/iReSign/IRTextFieldDrag.m: -------------------------------------------------------------------------------- 1 | // 2 | // IRTextFieldDrag.m 3 | // iReSign 4 | // 5 | // Created by Esteban Bouza on 01/12/12. 6 | // 7 | 8 | #import "IRTextFieldDrag.h" 9 | 10 | @implementation IRTextFieldDrag 11 | 12 | - (void)awakeFromNib { 13 | [self registerForDraggedTypes:@[NSFilenamesPboardType]]; 14 | } 15 | 16 | - (BOOL)performDragOperation:(id )sender 17 | { 18 | NSPasteboard *pboard = [sender draggingPasteboard]; 19 | 20 | if ( [[pboard types] containsObject:NSURLPboardType] ) { 21 | NSArray *files = [pboard propertyListForType:NSFilenamesPboardType]; 22 | if (files.count <= 0) { 23 | return NO; 24 | } 25 | self.stringValue = [files objectAtIndex:0]; 26 | 27 | } 28 | return YES; 29 | } 30 | 31 | 32 | // Source: http://www.cocoabuilder.com/archive/cocoa/11014-dnd-for-nstextfields-drag-drop.html 33 | - (NSDragOperation)draggingEntered:(id )sender { 34 | 35 | if (!self.isEnabled) return NSDragOperationNone; 36 | 37 | NSPasteboard *pboard; 38 | NSDragOperation sourceDragMask; 39 | 40 | sourceDragMask = [sender draggingSourceOperationMask]; 41 | pboard = [sender draggingPasteboard]; 42 | 43 | if ( [[pboard types] containsObject:NSColorPboardType] ) { 44 | if (sourceDragMask & NSDragOperationCopy) { 45 | return NSDragOperationCopy; 46 | } 47 | } 48 | if ( [[pboard types] containsObject:NSFilenamesPboardType] ) { 49 | if (sourceDragMask & NSDragOperationCopy) { 50 | return NSDragOperationCopy; 51 | } 52 | } 53 | 54 | return NSDragOperationNone; 55 | } 56 | 57 | 58 | @end 59 | -------------------------------------------------------------------------------- /iReSign/iReSign/iReSign.xcodeproj/project.xcworkspace/xcshareddata/iReSign.xccheckout: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | IDESourceControlProjectFavoriteDictionaryKey 6 | 7 | IDESourceControlProjectIdentifier 8 | 55C76783-2CEC-4A8B-BA32-DF9DAB6B90C5 9 | IDESourceControlProjectName 10 | iReSign 11 | IDESourceControlProjectOriginsDictionary 12 | 13 | 43280492CE74ADAC7B7AD1393F0FB52CA2FE257C 14 | github.com:maciekish/iReSign.git 15 | 16 | IDESourceControlProjectPath 17 | iReSign/iReSign.xcodeproj 18 | IDESourceControlProjectRelativeInstallPathDictionary 19 | 20 | 43280492CE74ADAC7B7AD1393F0FB52CA2FE257C 21 | ../../.. 22 | 23 | IDESourceControlProjectURL 24 | github.com:maciekish/iReSign.git 25 | IDESourceControlProjectVersion 26 | 111 27 | IDESourceControlProjectWCCIdentifier 28 | 43280492CE74ADAC7B7AD1393F0FB52CA2FE257C 29 | IDESourceControlProjectWCConfigurations 30 | 31 | 32 | IDESourceControlRepositoryExtensionIdentifierKey 33 | public.vcs.git 34 | IDESourceControlWCCIdentifierKey 35 | 43280492CE74ADAC7B7AD1393F0FB52CA2FE257C 36 | IDESourceControlWCCName 37 | iReSign 38 | 39 | 40 | 41 | 42 | -------------------------------------------------------------------------------- /iReSign/README.md: -------------------------------------------------------------------------------- 1 | iReSign 2 | ======= 3 | 4 | iReSign allows iDevice app bundles (.ipa) files to be signed or resigned with a digital certificate from Apple for distribution. It can also create signed iDevice app bundles (.ipa) files from .xcarchive files. This tool is aimed at enterprises users, for enterprise deployment, when the person signing the app is different than the person(s) developing it. 5 | 6 | How to use 7 | ======= 8 | 9 | iReSign allows you to re-sign any unencrypted ipa-file with any certificate for which you hold the corresponding private key. iResign can also created a signed ipa-file from an xcarchive file. 10 | 11 | 1. Drag your unsigned .ipa or .xcarchive file to the top box, or use the browse button. 12 | 13 | 2. Enter your full certificate name from Keychain Access, for example "iPhone Developer: Firstname Lastname (XXXXXXXXXX)" in the bottom box. 14 | 15 | 3. Click ReSign! and wait. The resigned file will be saved in the same folder as the original file. 16 | 17 | License 18 | ======= 19 | 20 | Copyright (c) 2014 Maciej Swic 21 | 22 | Permission is hereby granted, free of charge, to any person obtaining a copy 23 | of this software and associated documentation files (the "Software"), to deal 24 | in the Software without restriction, including without limitation the rights 25 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 26 | copies of the Software, and to permit persons to whom the Software is 27 | furnished to do so, subject to the following conditions: 28 | 29 | The above copyright notice and this permission notice shall be included in 30 | all copies or substantial portions of the Software. 31 | 32 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 33 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 34 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

I tested the currently newest Facebook for iOS version 79.0, this patch may become invalid with newer version. 13 | 14 | ## About 15 | - Inspired by https://github.com/nabla-c0d3/ssl-kill-switch2, https://github.com/nabla-c0d3/ssl-kill-switch2/issues/13 16 | - Contents of `DyldPatcher` is created by [depoon](https://github.com/depoon), the original repo is https://github.com/depoon/iOSDylibInjectionDemo, and an article about this https://medium.com/@kennethpoon/how-to-perform-ios-code-injection-on-ipa-files-1ba91d9438db#.mwx82zyds 17 | - The `iResign` is modified version of https://github.com/maciekish/iReSign, created by Maciej Swic. I added support for injected libraries. 18 | - The Aspects library is created by Peter Steinberger, licensed under MIT, the original repo is https://github.com/steipete/Aspects 19 | 20 | ## Instructions 21 | 22 | **Update 20170319** 23 | 24 | I've developed a new tool to finish this steps in more simple way, see: 25 | 26 | https://github.com/Naituw/IPAPatch 27 | 28 | **Original Instructions** 29 | 30 | 1. Prepare `Facebook_extenstion_removed.ipa` 31 | - Get decrypted Facebook ipa, wether from a jailbroken device or ipa download site (I'm using ipa downloaded from http://www.iphonecake.com) 32 | - Unzip ipa, Remove `Payload/Facebook.app/Plugins` folder, which contains App Extensions. 33 | - Zip the `Payload` folder, and rename to `Facebook_extenstion_removed.ipa` 34 | 35 | 2. Inject Code to `Facebook_extenstion_removed.ipa` 36 | - Build `DyldXcodeProject`, make sure the target is selected to real device (NOT iPhone Simulators), copy the result framework's binary file to a folder named `DyldsForInjection` 37 | - Use the script provide in `DyldPatcher`, patch the binary we generated, to `Facebook_extenstion_removed.ipa`, the patched file is named `Facebook_extenstion_removed-patched.ipa` 38 | 39 | cd DyldPatcher 40 | ./patchapp.sh Facebook_extenstion_removed.ipa DyldsForInjection 41 | 42 | 3. Resign `Facebook_extenstion_removed-patched.ipa` 43 | - Use the modified version of `iResign` to resign the file, the result file is `Facebook_extenstion_removed-patched-resigned.ipa`, this version will sign the dyld we injected correctly. 44 | 45 | 4. Install and Run 46 | - Install `Facebook_extenstion_removed-patched-resigned.ipa` via Xcode 47 | - Capture HTTPS requests like other apps with `Charles`! 48 | 49 | -------------------------------------------------------------------------------- /DyldPatcher/patchapp.sh: -------------------------------------------------------------------------------- 1 | 2 | OPTOOL="./optool" 3 | 4 | IPA=$1 5 | DYLIB_FOLDER=$2 6 | TMPDIR=".patchapp.cache" 7 | 8 | # 9 | # Usage / syntax 10 | # 11 | function usage { 12 | if [ "$2" == "" -o "$1" == "" ]; then 13 | cat < [/path/to/your/file.mobileprovision]" 15 | Where 'command' is one of:" 16 | info - Show the information required to create a Provisioning Profile 17 | that matches the specified .ipa file 18 | patch - Inject the current Theos tweak into the specified .ipa file. 19 | Requires that you specify a .mobileprovision file. 20 | 21 | USAGE 22 | fi 23 | } 24 | 25 | # 26 | # 27 | # 28 | 29 | function copy_dylib_and_load { 30 | 31 | 32 | # copy the files into the .app folder 33 | echo '[+] Copying .dylib dependences into "'$TMPDIR/Payload/$APP'"' 34 | cp -rf $DYLIB_FOLDER $TMPDIR/Payload/$APP/Dylibs 35 | 36 | # re-sign Frameworks, too 37 | echo "APPDIR=$APPDIR" 38 | for file in `ls -1 $APPDIR/Dylibs`; do 39 | echo -n ' ' 40 | echo "Install Load: $file -> @executable_path/Dylibs/$file" 41 | $OPTOOL install -c load -p "@executable_path/Dylibs/$file" -t $APPDIR/$APP_BINARY >& /dev/null 42 | done 43 | 44 | 45 | #-------- 46 | 47 | if [ "$?" != "0" ]; then 48 | echo "Failed to inject "${DYLIB##*/}" into $APPDIR/${APP_BINARY}.

Aspects automatically deals with calling super and is easier to use than regular method swizzling. 7 | 8 | This is stable and used in hundreds of apps since it's part of [PSPDFKit, an iOS PDF framework that ships with apps like Dropbox or Evernote](http://pspdfkit.com), and now I finally made it open source. 9 | 10 | Aspects extends `NSObject` with the following methods: 11 | 12 | ``` objc 13 | /// Adds a block of code before/instead/after the current `selector` for a specific class. 14 | /// 15 | /// @param block Aspects replicates the type signature of the method being hooked. 16 | /// The first parameter will be `id`, followed by all parameters of the method. 17 | /// These parameters are optional and will be filled to match the block signature. 18 | /// You can even use an empty block, or one that simple gets `id`. 19 | /// 20 | /// @note Hooking static methods is not supported. 21 | /// @return A token which allows to later deregister the aspect. 22 | + (id)aspect_hookSelector:(SEL)selector 23 | withOptions:(AspectOptions)options 24 | usingBlock:(id)block 25 | error:(NSError **)error; 26 | 27 | /// Adds a block of code before/instead/after the current `selector` for a specific instance. 28 | - (id)aspect_hookSelector:(SEL)selector 29 | withOptions:(AspectOptions)options 30 | usingBlock:(id)block 31 | error:(NSError **)error; 32 | 33 | /// Deregister an aspect. 34 | /// @return YES if deregistration is successful, otherwise NO. 35 | id aspect = ...; 36 | [aspect remove]; 37 | ``` 38 | 39 | Adding aspects returns an opaque token of type `AspectToken` which can be used to deregister again. All calls are thread-safe. 40 | 41 | Aspects uses Objective-C message forwarding to hook into messages. This will create some overhead. Don't add aspects to methods that are called a lot. Aspects is meant for view/controller code that is not called 1000 times per second. 42 | 43 | Aspects calls and matches block arguments. Blocks without arguments are supported as well. The first block argument will be of type `id`. 44 | 45 | When to use Aspects 46 | ------------------- 47 | Aspect-oriented programming (AOP) is used to encapsulate "cross-cutting" concerns. These are the kind of requirements that *cut-across* many modules in your system, and so cannot be encapsulated using normal object oriented programming. Some examples of these kinds of requirements: 48 | 49 | * *Whenever* a user invokes a method on the service client, security should be checked. 50 | * *Whenever* a user interacts with the store, a genius suggestion should be presented, based on their interaction. 51 | * *All* calls should be logged. 52 | 53 | If we implemented the above requirements using regular OOP there'd be some drawbacks: 54 | 55 | Good OOP says a class should have a single responsibility, however adding on extra *cross-cutting* requirements means a class that is taking on other responsibilites. For example you might have a **StoreClient** that is supposed to be all about making purchases from an online store. Add in some cross-cutting requirements and it might also have to take on the roles of logging, security and recommendations. This is not great because: 56 | 57 | * Our StoreClient is now harder to understand and maintain. 58 | * These cross-cutting requirements are duplicated and spread throughout our app. 59 | 60 | AOP lets us modularize these cross-cutting requirements, and then cleanly identify all of the places they should be applied. As shown in the examples above cross-cutting requirements can be either technical or business focused in nature. 61 | 62 | ## Here are some concrete examples: 63 | 64 | 65 | Aspects can be used to **dynamically add logging** for debug builds only: 66 | 67 | ``` objc 68 | [UIViewController aspect_hookSelector:@selector(viewWillAppear:) withOptions:AspectPositionAfter usingBlock:^(id aspectInfo, BOOL animated) { 69 | NSLog(@"View Controller %@ will appear animated: %tu", aspectInfo.instance, animated); 70 | } error:NULL]; 71 | ``` 72 | 73 | ------------------- 74 | It can be used to greatly simplify your analytics setup: 75 | https://github.com/orta/ARAnalytics 76 | 77 | ------------------- 78 | You can check if methods are really being called in your test cases: 79 | ``` objc 80 | - (void)testExample { 81 | TestClass *testClass = [TestClass new]; 82 | TestClass *testClass2 = [TestClass new]; 83 | 84 | __block BOOL testCallCalled = NO; 85 | [testClass aspect_hookSelector:@selector(testCall) withOptions:AspectPositionAfter usingBlock:^{ 86 | testCallCalled = YES; 87 | } error:NULL]; 88 | 89 | [testClass2 testCallAndExecuteBlock:^{ 90 | [testClass testCall]; 91 | } error:NULL]; 92 | XCTAssertTrue(testCallCalled, @"Calling testCallAndExecuteBlock must call testCall"); 93 | } 94 | ``` 95 | ------------------- 96 | It can be really useful for debugging. Here I was curious when exactly the tap gesture changed state: 97 | 98 | ``` objc 99 | [_singleTapGesture aspect_hookSelector:@selector(setState:) withOptions:AspectPositionAfter usingBlock:^(id aspectInfo) { 100 | NSLog(@"%@: %@", aspectInfo.instance, aspectInfo.arguments); 101 | } error:NULL]; 102 | ``` 103 | 104 | ------------------- 105 | Another convenient use case is adding handlers for classes that you don't own. I've written it for use in [PSPDFKit](http://pspdfkit.com), where we require notifications when a view controller is being dismissed modally. This includes UIKit view controllers like `MFMailComposeViewController` and `UIImagePickerController`. We could have created subclasses for each of these controllers, but this would be quite a lot of unnecessary code. Aspects gives you a simpler solution for this problem: 106 | 107 | ``` objc 108 | @implementation UIViewController (DismissActionHook) 109 | 110 | // Will add a dismiss action once the controller gets dismissed. 111 | - (void)pspdf_addWillDismissAction:(void (^)(void))action { 112 | PSPDFAssert(action != NULL); 113 | 114 | [self aspect_hookSelector:@selector(viewWillDisappear:) withOptions:AspectPositionAfter usingBlock:^(id aspectInfo) { 115 | if ([aspectInfo.instance isBeingDismissed]) { 116 | action(); 117 | } 118 | } error:NULL]; 119 | } 120 | 121 | @end 122 | ``` 123 | 124 | Debugging 125 | --------- 126 | Aspects identifies itself nicely in the stack trace, so it's easy to see if a method has been hooked: 127 | 128 | 129 | 130 | Using Aspects with non-void return types 131 | ---------------------------------------- 132 | 133 | You can use the invocation object to customize the return value: 134 | 135 | ``` objc 136 | [PSPDFDrawView aspect_hookSelector:@selector(shouldProcessTouches:withEvent:) withOptions:AspectPositionInstead usingBlock:^(id info, NSSet *touches, UIEvent *event) { 137 | // Call original implementation. 138 | BOOL processTouches; 139 | NSInvocation *invocation = info.originalInvocation; 140 | [invocation invoke]; 141 | [invocation getReturnValue:&processTouches]; 142 | 143 | if (processTouches) { 144 | processTouches = pspdf_stylusShouldProcessTouches(touches, event); 145 | [invocation setReturnValue:&processTouches]; 146 | } 147 | } error:NULL]; 148 | ``` 149 | 150 | Installation 151 | ------------ 152 | The simplest option is to use `pod "Aspects"`. 153 | 154 | You can also add the two files `Aspects.h/m` to your project. There are no further requirements. 155 | 156 | Compatibility and Limitations 157 | ----------------------------- 158 | Aspects uses quite some runtime trickery to achieve what it does. You can mostly mix this with regular method swizzling. 159 | 160 | An important limitation is that for class-based hooking, a method can only be hooked once within the subclass hierarchy. [See #2](https://github.com/steipete/Aspects/issues/2) 161 | This does not apply for objects that are hooked. Aspects creates a dynamic subclass here and has full control. 162 | 163 | KVO works if observers are created after your calls `aspect_hookSelector:` It most likely will crash the other way around. Still looking for workarounds here - any help appreciated. 164 | 165 | Because of ugly implementation details on the ObjC runtime, methods that return unions that also contain structs might not work correctly unless this code runs on the arm64 runtime. 166 | 167 | Credits 168 | ------- 169 | The idea to use `_objc_msgForward` and parts of the `NSInvocation` argument selection is from the excellent [ReactiveCocoa](https://github.com/ReactiveCocoa/ReactiveCocoa) from the GitHub guys. [This article](http://codeshaker.blogspot.co.at/2012/01/aop-delivered.html) explains how it works under the hood. 170 | 171 | 172 | Supported iOS & SDK Versions 173 | ----------------------------- 174 | 175 | * Aspects requires ARC. 176 | * Aspects is tested with iOS 7+ and OS X 10.7 or higher. 177 | 178 | License 179 | ------- 180 | MIT licensed, Copyright (c) 2014 Peter Steinberger, steipete@gmail.com, [@steipete](http://twitter.com/steipete) 181 | 182 | 183 | Release Notes 184 | ----------------- 185 | 186 | Version 1.4.2 187 | 188 | - Allow to hook different subclasses. 189 | - Smaller tweaks. 190 | 191 | Version 1.4.1 192 | 193 | - Rename error codes. 194 | 195 | Version 1.4.0 196 | 197 | - Add support for block signatures that match method signatures.
