iOS逆向篇——Cycript调试App

作者: Lucky_Blue | 来源:发表于2021-03-24 09:29 被阅读0次

现在越狱后的手机都是自带安装了Cycript和adv-cmds，如果没有即添加软件源https://apt.bingner.com安装好。

Cycript

adv-cmds
先通过SSH登录到服务器（iPhone）

ps 命令

列出所有进程 ps -A（当前手机打开了腾讯动漫）

可以从上图找到11095是腾讯动漫的进程id（pid），ComicReader是腾讯动漫的进程名称
搜索进程：ps –A | grep 关键词

i-57:~ root# ps -A | grep ComicReader
11095 ??         0:05.50 /var/containers/Bundle/Application/015C9AB9-4440-492F-911B-6DEC6915FBFC/ComicReader.app/ComicReader
11121 ttys000    0:00.01 grep ComicReader
i-57:~ root#

附加App直接调试 cycript -p 进程名称/进程的编号

cycript -p 11095
或者
cycript -p ComicReader
cy#

获取BundleIdentifier

i-57:~ root# cycript -p 1369
cy# [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleIdentifier"]

启动和退出

启动：cycript -p 进程名称
退出：control + d
清屏：command + r

Cycript 常用语法

UIApp = UIApplication.sharedApplication()

cy# UIApp
#"<UIApplication: 0x104f04470>"

用内存地址获取对象：#内存地址

cy# #0x104f04470
#"<UIApplication: 0x104f04470>"

查看对象的所有成员变量：*对象

cy# *UIApp
{isa:UIApplication,_responderFlags:@error,_delegate:#"<TencentXGPushAppDelegate: 0x280e46cc0>",_remoteControlEventObservers:0,_topLevelNibObjects:null,_networkResourcesCurrentlyLoadingCount:0,_hideNetworkActivityIndicatorTimer:null,_statusBar:null,_statusBarRequestedStyle:0,_statusBarWindow:null,_observerBlocks:@[],_postCommitActions:@[],_postCommitActionsNeedToSynchronize:false,_mainStoryboardName:null,_idleModeController:null,_displayLayoutMonitor:null,_systemUserInterfaceStyle:0,_eventFetcher:#"<UIEventFetcher: 0x282264540>",_eventDispatcher:#"<UIEventDispatcher: 0x281569620>",_applicationFlags:@error,_keyCommandToken:#"<BSSimpleAssertion: 0x281445110; identifier: com.apple.backboard.hid.delivery; reason: 2-keycmds; valid: YES>",_physicalKeyCommandMap:@{},_physicalKeycodeMap:[NSOrderedSet orderedSetWithArray:@[]]],_alwaysHitTestsForMainScreen:false,_backgroundHitTestWindow:null,_appInfo:#"<_UIApplicationInfoParser: 0x2830656c0>",_actionsPendingInitialization:null,_idleTimerDisabledReasons:[NSSet setWithArray:@[]]],_keyRepeatAction:null,_currentTimestampWhenFirstTouchCameDown:0,_currentLocationWhereFirstTouchCameDown:{x:0,y:0},_saveStateRestorationArchiveWithFileProtectionCompleteUntilFirstUserAuthentication:false,_fenceTaskAssertion:null,_cachedSystemAnimationFence:null,_systemNavigationAction:null,_activityContinuationManager:#"<UIActivityContinuationManager: 0x28156e310>",__gestureEnvironment:#"<UIGestureEnvironment: 0x283061d50>",_forceStageObservable:null,_HIDGameControllerEventObserver:null,_HIDGameControllerEventQueue:null,_motionNotificationGenerator:null,_appState:#"<UISApplicationState: 0x281b633c0>",_applicationPushRegistry:#"<PKPushRegistry: 0x2838401e0>",_storyboardInitialMenu:null,_endpointMonitor:#"<BSServiceConnectionEndpointMonitor: 0x283861ef0; service: com.apple.frontboard.open; active>",optOutOfRTL:false,_isDisplayingActivityContinuationUI:false,_applicationWantsGESEvents:false,_shortcutService:null,___queuedOrientationChange:null,__expectedViewOrientation:1}

递归打印view的所有子控件：view.recursiveDescription().toString()

UIApp.keyWindow.recursiveDescription().toString()

定义变量：var 变量名 = 变量值

cy# var window = UIApp.keyWindow
#"<UIWindow: 0x104f1be40; frame = (0 0; 375 667); gestureRecognizers = <NSArray: 0x281552d30>; layer = <UIWindowLayer: 0x281b753e0>>"

定义函数：function 函数名(...) { ... }

cy# function sum(a, b) {return a+b;}
cy# sum(2,3)
5

筛选出某种类型的对象：choose(类型)

cy# choose(UIViewController)
[#"<UISystemInputAssistantViewController: 0x106468630>",#"<UIEditingOverlayViewController: 0x10649e1d0>",#"<ComicHomeViewController: 0x105843000>",#"<ComicNavgationController: 0x105849000>",#"<VPlaygoundViewController: 0x10584e200>",#"<ComicNavgationController: 0x105850200>",#"<WaitHomeViewController: 0x105853a00>",#"<BookShelfViewController: 0x10585aa00>",#"<ComicNavgationController: 0x10585b000>",#"<MyViewController: 0x10585b600>",#"<ComicNavgationController: 0x10585bc00>",#"<ComicNavgationController: 0x105867400>",#"<UpdateChannelViewController: 0x105883a00>",#"<UpdateChannelSubViewController: 0x1058ee400>",#"<UpdateChannelSubViewController: 0x1058f5000>",#"<UIInputWindowController: 0x10595b000>",#"<ADWebViewController: 0x105972a00>",#"<ComicTabBarController: 0x105040400>",#"<ADWebViewController: 0x105137000>",#"<GenderSelectionViewController: 0x1051e8000>"]

对`.cy`文件的应用

.cy文件是对Cycript的封装，方便提供一些比较常用的函数。

(function(exports) {
    var invalidParamStr = 'Invalid parameter';

    // app id
    LBAppId = [NSBundle mainBundle].bundleIdentifier;

lbtool.cy文件用法
用@import + 文件名导入文件

i-57:~ root# cycript -p 11424
cy# @import lbtool
{}

获取当前显示的控制器

cy# LBFrontVc()
#"<ACReaderViewController: 0x1048ae600>"

获取view的层级结构

cy# LBSubviews(LBFrontVc().view)
`<UIView: 0x117c54a40; frame = (0 0; 375 667); autoresize = W+H; layer = <CALayer: 0x283adab00>>
   | <ACReaderEngineView: 0x117c4b850; frame = (0 0; 375 667); autoresize = W+H; gestureRecognizers = <NSArray: 0x283483720>; layer = <CALayer: 0x283acd3c0>>
   |    | <ACZoomScrollView: 0x105b15600; baseClass = UIScrollView; frame = (0 0; 375 667); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x2834be790>; layer = <CALayer: 0x283acd660>; contentOffset: {0, 0}; contentSize: {0, 0}; adjustedContentInset: {0, 0, 0, 0}>
   |    |    | <UICollectionView: 0x105b19600; frame = (0 0; 375 667); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x283491920>; layer = <CALayer: 0x283acdbe0>; contentOffset: {0, 10}; contentSize: {375, 2130}; adjustedContentInset: {0, 0, 0, 0}; layout: <UICollectionViewFlowLayout: 0x11bf46e50>; dataSource: <ACReaderEngineView: 0x117c4b850; frame = (0 0; 375 667); autoresize = W+H; gestureRecognizers = <NSArray: 0x283483720>; layer = <CALayer: 0x283acd3c0>>>
