iOS 逆向工程-淺析內存地址

ios 逆向工程

剛進一個新公司，公司的大牛直接分給一個課題研究任務，直接懵逼了，/(ㄒoㄒ)/~~ 想哭，世界就是這麼酷酷的，硬着頭上唄，一切行動聽指揮-----> 就研究了下，在此分享下，有需要的看下，有不足之處請指點一二，謝謝各位大大，O(∩_∩)O哈哈~

前言

ios逆向工程指的是在軟件層面上進行逆向分析的一個過程。如果想要達到對ios軟件較強的逆向分析能力，最好能非常熟悉ios設備的硬件構成、ios系統的運行原理，還要具備豐富的ios開發經驗，比如：拿到一個App之後能清晰的推斷出這個App使用的技術，包括引用了那些FrameWork，那些經典的第三方代碼，以及整個App工程大致的文件個數等。
逆向工程的主要兩個作用：首先是攻破目標程序，拿到關鍵信息，可以歸類於安全相關的逆向工程，其次是借鑑他人的程序功能來開發自己的軟件，可以歸類於開發相關的逆向工程
與安全相關的ios逆向工程
ios 逆向工程最突出的應用領域就是與安全相關的，比如：通過逆向一個金融App，來評定這個軟件的安全等級，安全專家通過逆向ios病毒，來找到殺毒的方法，安全公司通過逆向ios系統電話、短信功能，來構建一個手機防火牆

a.評定安全等級
ios中那些具有交易功能的App一般會先加密敏感數據，然後將加密過的數據存儲在本地或通過互聯網傳輸，而如果安全意識不夠強，就完全有可能將重要信息直接用明文保存或傳輸，安全隱患極大。App雖然可以將低維的攻擊防守得如銅牆鐵壁一般，但是擋不住高維的逆向攻擊，不過不可以據此得出App不安全的結論，因爲ios逆向工程的使用均來自一個前提：ios越獄，在這種環境下，我們使用這些逆向工程技術來分析評估目標App中可被攻擊點有多少，可攻擊點越少的自然就越安全。

b. 逆向惡意軟件
ios 是隻能移動終端操作系統，它同計算機操作系統沒有本質區別，惡意軟件就是通過逆向工程定位系統和軟件漏洞，利用漏洞滲透進目標主機，獲取敏感數據

與開發相關的ios逆向工程
開發者可以逆向系統調用，在自己的程序裏使用一些文檔中沒有提及的私有功能，還可以逆向一些經典的軟件等
a.逆向系統調用
開發者編寫的軟件能夠運行在操作系統中，提供各種各樣的功能，是因爲操作系統本身已經內嵌了這些功能，軟件只是拿來重組使用。絕大多數的App的實現都源於公開的開發文檔，而不能使用諸如鎖屏，關機等文檔中不涉及的功能，如果你的程序面向Cydia,那麼不採用非公開功能將導致程序幾乎沒有競爭力，故可以通過逆向ios系統調用，還原系統實現相應功能的代碼，並應用到自己的程序中。
b.借鑑別的軟件
逆向工程最受歡迎的應用場合就是“借鑑”他人的軟件功能。

一、ios 越獄

ios 完美越獄和不完美越獄

完美越獄，越獄後的iPhone可以正常關機和重啓
不完美越獄，iPhone一旦關機後再開機時，屏幕就會一直停留在啓動畫面，也就是“白蘋果”狀態。或者能正常開機，但已經安裝的破解軟件都無法正常使用，需要將設備與PC連接後，使用軟件進行引導才能使用。一般說來，在蘋果發佈新的iOS固件後，針對該固件的不完美越獄會先發布，隨後完美越獄纔可能發佈，一般較新的系統版本，均爲不完美越獄

越獄方法推薦
PP助手：http://jailbreak.25pp.com/
ps：不同機型，不同系統，有的可以越獄，有的不可以
http://jailbreak.25pp.com/iphone5syueyu/

如何判斷是否越獄成功?

桌面是否有cydia

2.工具判斷(比如pp助手)

使用cydia安裝軟件

二、 Mac遠程登錄到iphone

我們經常在Mac的終端上，通過敲一下命令來完成一些操作，iOS 和Mac OSX 都是基於Drawin（蘋果的一個基於Unix的開源系統內核）,所以ios中同樣支持終端的命令行操作，在逆向工程中，可以使用命令行來操縱iphone。

爲了建立連接需要用到 SSH 和OpenSSH
SSH： Secure Shell的縮寫，表示“安全外殼協議”，是一種可以爲遠程登錄提供安全保障的協議，使用SSH，可以把所有傳輸的數據進行加密，"中間人"攻擊方式就不可能實現，能防止DNS 欺騙和IP欺騙

OpenSSH：是SSH協議的免費開源實現，可以通過OpenSSH的方式讓Mac遠程登錄到iphone,此時進行訪問時，Mac 是客戶端 iphone是服務器

使用OpenSSH遠程登錄步驟如下

在iphone上安裝cydia 安裝OpenSSH工具（軟件源http://apt.saurik.com）

OpenSSH的具體使用步驟可以查看Description中的描述

第一種登錄方式可以使用WIFI

具體使用步驟

確保Mac和iphone在同一個局域網下（連接同一個WIFI）
在Mac的終端輸入ssh賬戶名@服務器主機地址，比如ssh [email protected]（這裏服務器是手機）初始密碼 alpine
登錄成功後就可以使用終端命令行操作iphone
退出登錄 exit

ps：ios下2個常用賬戶 root、moblie

root：最高權限賬戶，HOME是 /var/root
moblie :普通權限賬戶，只能操作一些普通文件，不能操作別的文件,HOME是/var/mobile
登錄moblie用戶：root moblie@服務器主機地址
root和mobli用戶的初始登錄密碼都是alpine

第二種登錄方式通過USB進行SSH登錄

22端口
端口就是設備對外提供服務的窗口，每個端口都有個端口號,範圍是0--65535，共2^16個
有些端口是保留的，已經規定了用途，比如 21端口提供FTP服務，80端口是提供HTTP服務，22端口提供SSH服務，更多保留端口號課參考鏈接
iphone 默認是使用22端口進行SSH通信，採用的是TCP協議
默認情況下，由於SSH走的是TCP協議，Mac是通過網絡連接的方式SSH登錄到iphone，要求iPhone連接WIFI，爲了加快傳輸速度，也可以通過USB連接的方式進行SSH登錄，Mac上有個服務程序usbmuxd（開機自動啓動），可以將Mac的數據通過USB傳輸到iphone，路徑是/System/Library/PrivateFrameworks/mobileDevice.framework/Resources/usbmuxd

usbmuxd的使用
下載usbmuxd工具包，下載v1.0.8版本，主要用到裏面的一個python腳本： tcprelay.py, 下載鏈接
將iphone的22端口（SSH端口）映射到Mac本地的10010端口
cd ~/Documents/usbmux-1.08/python-client
python tcprelay.py -t 22:10010
加上 -t 參數是爲了能夠同時支持多個SSH連接，端口映射完畢後，以後如果想跟iphone的22端口通信，直接跟Mac本地的10010端口通信就可以了，新開一個終端界面，SSH登錄到Mac本地的10010端口，usbmuxd會將Mac本地10010端口的TCP協議數據，通過USB連接轉發到iphone的22 端口，遠程拷貝文件也可以直接跟Mac本地的10010端口通信，如：scp -p 10010 ~/Desktop/1.txt root@localhost:~/test 將Mac上的_{/Desktop/1.txt文件，拷貝到iphone上的}/test路徑。

先開一個終端，先完成端口映射
*cd 到usbmuxd文件夾路徑
python tcprelay.py -t 22:10010

再開一個端口
注入手機

ssh root@localhost -p 10010
Zhanghua123:~ root# cycript -p SpringBoard

ps：切記第一個終端不可以關閉，纔可以保持端口映射狀態

三、 Cycript的使用

Cycript 是Objective-C++ JavaScript Java等語法的混合物，可以用來探索，修改，調試正在運行的Mac\ios App

官網：http://www.cycript.org/
文檔: http://www.cycript.org/manual
通過Cycdia 安裝Cycript，就可以在iphone上調試運行中的APP

使用上面usb鏈接的方式進入iphone
Zhanghua123:~ root# ps -e

會出現很多進程
看var開頭的，可以看到開的進程

cycript 基本語法
定義變量
var 變量名 = 變量值
用內存地址獲取對象
內存地址
查看已經加載的所有OC類
ObjectiveC.classes
查看對象的所有成員變量
*對象
遞歸打印view的所有子控件
view.recursiveDescription().toString()
篩選出某種類型的對象
choose(UIViewController)
choose(UITableViewCell)

注入手機
cycript Zhanghua123:~ root# cycript -p SpringBoard

如果輸入中文，要轉碼一次

http://tool.chinaz.com/tools/unicode.aspx

添加一個view

cy# v2 = [[UIView alloc]init]
#"<UIView: 0x111b90ab0; frame = (0 0; 0 0); layer = <CALayer: 0x11002fe40>>"
cy# v2.frame
(extern "C" struct CGRect ":frame"(id, SEL))
cy# [v2 frame]
{0:{0:0,1:0},1:{0:0,1:0}}
cy# v2.frame = {0:{0:0,1:0},1:{0:320,1:200}}
{0:{0:0,1:0},1:{0:320,1:200}}

cy# [view addSubview: v2]
cy# v2
#"<UIView: 0x111b90ab0; frame = (0 0; 320 200); layer = <CALayer: 0x11002fe40>>"
cy# v2.backgroundColor = [UIColor redColor]
#"UIExtendedSRGBColorSpace 1 0 0 1"
cy#

Cycript 封裝的一些庫
從下面地址下載資源
https://github.com/CoderMJLee/mjcript
然後安裝在手機的 Device/usr/lib路徑下
具體使用如下：

Zhanghua123:~ root# cycript -p SpringBoard
cy# @import mjcript
{}
cy# MJAppId
@"com.apple.springboard"
cy# MJAppPath
@"/System/Library/CoreServices/SpringBoard.app"
cy# MJDocPath
@"/var/mobile/Documents"
cy# MJCachesPath
@"/var/mobile/Library/Caches"
cy#

實現清楚SpringBoard 上面app的推送通知數目

登錄
看是否是脫殼的（沒有打印出，表示已經脫殼）

cuilinhaodeMacBook-Pro:~ cuilinhao$ cd Desktop/SpringBoard/
cuilinhaodeMacBook-Pro:SpringBoard cuilinhao$ ls
Headers     SpringBoard
cuilinhaodeMacBook-Pro:SpringBoard cuilinhao$ otool -l Springboard | grep cycpt
cuilinhaodeMacBook-Pro:SpringBoard cuilinhao$ class-dump -H SpringBoard -o Headers
cuilinhaodeMacBook-Pro:SpringBoard cuilinhao$

進入SpringBoard並引入庫

Zhanghua123:~ root# cycript -p SpringBoard
cy# @import mjcript

測試查找，通過顯示與隱藏的方式看紅色數目是哪個類

cy# #0x10ac11980.hidden = 1
1
cy# #0x10ac11980.hidden = 1
1
cy# #0x10ac11980.hidden = 0

四、sh腳本文件

將經常執行的一系列終端命令行放到sh腳本文件中（shell），然後執行腳本文件，可以通過sh、bash、source命令來執行sh腳本文件
sh bash
當前shell環境會啓動一個子進程來執行腳本文件，執行後返回到父進程的shell環境，執行cd時，在子進程中會進入到cd目錄，但是在父進程中環境並沒有改變，也就是說目錄沒有改變
source
在當前的shell環境下執行腳本文件，執行cd後會跳轉到cd的目錄，source可以用一個點.來代替，比如“.test.sh”

五、 ios 脫殼

脫殼就是摘掉殼程序，加未加密的可執行文件還原出來，脫殼主要有2種方法：硬脫殼，動態脫殼
硬脫殼就是直接執行解密算法，動態脫殼，執行殼程序，將真實的內容解密出來，即熱內存中的可執行文件是已經解密過的，則我們可以直接導出，由於手機程序比較複雜，ios 中常用的是硬脫殼。

ios 中有很多好用的脫殼工具

Clutch：https://github.com/KJCracks/Clutch
dumpdecrypted: https://github.com/stefanesser/dumpdecrypted/

class-dump
class-dump的作用就是把Mach-O文件的class信息給dump出來（把類信息給導出來），生成對應的.h頭文件
官方網址： http://stevenygard.com/projects/class-dump/
下載完工具包以後將class-dump文件複製到Mac的/usr/local/bin目錄，這樣在終端就能識別class-dump命令了
常用的格式：class-dump -H Mach-O文件路徑 -o 頭文件存放目錄
ps： -H表示要生成頭文件 -O用於制定頭文件的存放目錄
權限問題：

cuilinhaodeMacBook-Pro:脫殼 cuilinhao$ class-dump -H To-Do -o Headers
-bash: /usr/local/bin/class-dump: Permission denied

解決：cuilinhaodeMacBook-Pro:脫殼 cuilinhao$ chmod +x /usr/local/bin/class-dump

logo語法

六、Clutch

Clutch的配置

下載最新的Release版： https://github.com/KJCracks/Clutch/releases

去掉版本號，改名爲Clutch
將clutch文件拷貝到iphone的/usr/btn目錄

4.如果在iphone上執行Clutch指令，權限不夠，賦予“可執行的權限”

Clutch - 使用

列出已經安裝的APP：Clutch -i

Zhanghua123:~ root# Clutch -i

Installed apps:
1:   WiFi伴侶-安全上網管家 <com.eldxin7.wifibanlv>
2:   華夏萬家金服 <com.hxwj.WJJF>
3:   智仟匯 <com.zhidou.smart>
4:   悟空問答 - 超火爆全民問答討論社區 <com.ss.iphone.article.wenda>
5:   愛思加強版 <com.pd.A4Player>
6:   喜馬拉雅FM「聽書社區」電臺有聲小說相聲評書 <com.gemd.iting>
7:   聯璧金融-安全靠譜的理財平臺 <com.lincomb.licai>
8:   Microsoft To-Do <com.microsoft.to-do>
Zhanghua123:~ root#

輸入APP序號或者Bundle Id進行脫殼操作： clutch -d APP序號BundleId

脫殼成功後會生成一個ipa文件且會有一個ipa存放的路徑

4.檢驗一下是否脫殼成功
otool -l To-Do | grep crypt
cryptoff 16384
cycptsize 2490368
cryptid 0

當 cryptid 爲0 時表示已經脫殼成功

導出頭文件
class-dump -H To-Do -o Headers

dumpdecrypted 使用

下載源代碼，然後在源代碼目錄執行make指令進行編譯，獲得dylib動態庫文件
下載地址：https://github.com/stefanesser/dumpdecrypted/archive/master.zip

cuilinhaodeMacBook-Pro:~ cuilinhao$ cd /Users/cuilinhao/Desktop/dumpdecrypted-master
cuilinhaodeMacBook-Pro:dumpdecrypted-master cuilinhao$ ls
Makefile    README      dumpdecrypted.c
cuilinhaodeMacBook-Pro:dumpdecrypted-master cuilinhao$ make

將dylib文件拷貝到iphone上，放到/var/root目錄
終端進入dylib所在的目錄
使用環境變量DYLD_INSERT_LIBARIES將dylib注入到需要脫殼的可執行文件（可執行文件路徑可以通過ps -A查看獲取）
DYLD_INSERT_LIBRARIES=dumpdecrypted.dylib + 可執行文件路徑
.decrpted文件就是脫殼後的可執行文件
ps：在使用過程可能會遇到錯誤

錯誤主要是因爲對dylib所在的文件夾權限不夠
解決方案：將dylib放在用戶所在文件夾，如果是root用戶，就放在/var/root目錄，如果是moblie用戶，將dylib放在/var/moblie目錄

一鍵砸殼，僅供參考
一鍵砸殼：
砸殼命令

cuilinhaodeMacBook-Pro:~ cuilinhao$ cd /opt
cuilinhaodeMacBook-Pro:opt cuilinhao$ cd dump/frida-ios-dump/
cuilinhaodeMacBook-Pro:frida-ios-dump cuilinhao$ ls
LICENSE         dump.js         process.sh
README.md       dump.py         requirements.txt
cuilinhaodeMacBook-Pro:frida-ios-dump cuilinhao$ sudo ./dump.py com.tencent.xin

問題：
ios ImportError: No module named scp
解決方法

sudo pip install -r requirements.txt

七、 Reveal 安裝

Reveal 是一款調試ios程序UI界面的神器
官網： https://revealapp.com
下載： https://revealapp.com/download
破解版 https://pan.baidu.com/s/1lz9lwTKXD9bS8DnvT9gkBQ 提取密碼:b31u 【建議直接裝破解的，不然有坑】
建議下載至少Reveal4版本，支持USB連接調試
調試環境配置
iphone上安裝Reveal Loader
軟件源： http：//apt.so/codermjlee,不要安裝其他源的版本，有可能不支持新版Reveal
安裝完Reveal Loader後，打開[設置]，選擇需要調試的APP
[圖片上傳失敗...(image-b2610e-1525830769359)]
點擊電腦上的Reveal軟件，然後找到Reveal中RevealServer文件，覆蓋iphone的/Library/RHRevealLoader/RevealServer文件

ps：在iPhone上沒有RHRevealLoader文件夾，可以自己創建

重啓SpringBoard killall SpringBoard

有問題請參考下面鏈接
https://www.jianshu.com/p/51c539f61ab0

http://blog.sina.com.cn/s/blog_894d45e20102wtbo.html

八、Hopper 安裝

直接百度下載

使用如下：
砸殼之後ipa中有一個mach-o 文件

就這個

然後打開Hopper

看 reveal 的類 GZECBaseWebViewController

看僞代碼

九、安裝theos

一、安裝簽名工具ldid
1.先確保安裝了brew， https://brew.sh

$ /usr/bin/ruby -e "$(curl -fsSL
      https://raw.githubusercontent.com/Homebrew/install/master/install)"

利用brew 安裝ldid

brew install ldid

二、修改環境變量

編輯用戶的配置文件

vim ~/.bash_profile

在.bash_profile 文件後面加入以下2行

export THEOS=~/theos
export PATH=$THEOS/bin:$PATH

讓.bash_profile配置的環境變量立即生效

vim ~/.bash_profile

三、下載theos

建議在$THEOS目錄下載代碼(就是上面配置的~/theos目錄)

git clone --recursive https://github.com/theos/theos.git $THEOS

四、新建tweak項目
cd 到一個存放項目代碼的文件夾

cd ~/Desktop
nic.pl

選擇 iphone/tweak

填寫項目信息
Project Name
項目名稱

Package Name
項目ID （隨便寫）

Author/Maintainer Name
作者，直接敲回車按照默認

[iphone/tweak] MobileSubstrate Bundle filter
需要修改APP的Bundle Identifier （喜馬拉雅的是com.gemd.iting ）
可以通過Cycript 查看APP 的Bundle Identifier
[iphone/tweak] List of applications to terminate upon installation
直接敲回車就可以

   Project Name (required): ting_tweak
  Package Name [com.yourcompany.ting_tweak]: com.mj.ting
  Author/Maintainer Name [MJ Lee]:
  [iphone/tweak] MobileSubstrate Bundle filter [com.apple.springboard]:
  com.gemd.iting
  [iphone/tweak] List of applications to terminate upon installation (space-
  separated, '-' for none) [SpringBoard]:
  Instantiating iphone/tweak in ting_tweak/...
  Done.

五、編輯Makefile
在前面加入環境變量，寫清楚通過那個ip和端口訪問手機
THEOS_DEVICE_IP
THEOS_DEVICE_PORT

      export THEOS_DEVICE_IP=127.0.0.1
      export THEOS_DEVICE_PORT=10010
      include $(THEOS)/makefiles/common.mk
      TWEAK_NAME = ting_tweak
      ting_tweak_FILES = Tweak.xm
      include $(THEOS_MAKE_PATH)/tweak.mk
      after-install::
     install.exec "killall -9 SpringBoard"

如果不希望每個項目的Makefile都編寫環境變量，也可以添加到用戶配置文件中，編輯完畢之後 source ~/.bash_profile 讓配置生效

      $ vim ~/.bash_profile
      export THEOS=~/theos
      export PATH=$THEOS/bin:$PATH
      export THEOS_DEVICE_IP=127.0.0.1
      export THEOS_DEVICE_PORT=10010
      $ source ~/.bash_profile

安裝完成之後

cuilinhaodeMacBook-Pro:~ cuilinhao$ cd theos/
cuilinhaodeMacBook-Pro:theos cuilinhao$ ls
LICENSE.md  bin     lib     package.json    toolchain

drwxr-xr-x   7 cuilinhao  staff    224  4 26 10:04 vendor

進入bin 進行查看

cuilinhaodeMacBook-Pro:theos cuilinhao$ cd bin
cuilinhaodeMacBook-Pro:bin cuilinhao$ ls -l

cuilinhaodeMacBook-Pro:bin cuilinhao$

配置路徑，使nic.pl 讓在任何地方訪問到

export THEOS=~/theos
export PATH=$THEOS/bin:$PATH

配置完之後查看

cuilinhaodeMacBook-Pro:~ cuilinhao$ echo $PATH
/Users/cuilinhao/.rvm/gems/ruby-2.2.2/bin:/Users/cuilinhao/.rvm/gems/ruby-2.2.2@global/bin:/Users/cuilinhao/.rvm/rubies/ruby-2.2.2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/cuilinhao/.rvm/bin
cuilinhaodeMacBook-Pro:~ cuilinhao$

ps: 如果配置完之後，還沒有出現路徑，執行命令 source .bash_profile 使路徑生效

參考：http://3code.info/blog/2016/11/2_Theos_-install&run.html

六、編寫代碼
打開tweak.xm 文件

%hook SBIconParallaxBadgeView

- (id)init
{
    return nil;
}

%end

七、編譯-打包-安裝

編譯

make

打包成deb

make package

安裝（默認會自動重啓Springboard）

make install

八、可能遇到的問題

-make package的錯誤

Can't locate IO/Compress/Lzma.pm in @INC (you may need to install the
  IO::Compress::Lzma module) (@INC contains: /Library/Perl/5.18/darwin-
  thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-
  thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.2
  /System/Library/Perl/5.18/darwin-thread-multi-2level

  /Users/mj/theos/bin/dm.pl line 12.
  BEGIN failed--compilation aborted at /Users/mj/theos/bin/dm.pl line 12.
  make: *** [internal-package] Error 2

錯誤是因爲打包壓縮方式有問題，改成gzip壓縮就可以了
修改dm.pl 文件，用#號註釋掉下面兩句

vim $THEOS/vendor/dm.pl/dm.pl
 #use IO::Compress::Lzma;
 #use IO::Compress::Xz;

修改deb.mk 文件第6行的壓縮方式爲gzp

vim $THEOS/makefiles/package/deb.mk
_THEOS_PLATFORM_DPKG_DEB_COMPRESSION ?= gzip

2 -make 錯誤

 Error: You do not have an SDK in
  /Library/Developer/CommandLineTools/Platforms/iPhoneOS.platform/Developer/S
  DKs

是因爲xcode 導致路徑（有可能安裝了好幾個xcode），需要指定一下xcode

sudo xcode-select --switch
/Applications/Xcode.app/Contents/Developer/

在make是出現Nothing

> Making all for tweak xxx...
  make[2]: Nothing to be done for `internal-library-compile'.

是因爲之前已經編譯過，有緩存導致的，clean一下即可

make clean
make

實現騰訊視頻播放去除廣告

找到騰訊ipa，進行砸殼處理
使用class-dump 導出頭文件
通過Reveal查看播放視圖view

4.如果只去除廣告的view，可能會清除廣告不完善，故清除整個vc，但在QNBPlayerVideoAdsViewController控制器中沒有找到對應的init方法，那隻能去找對應的父類

5.重寫父類的init方法

獲取bundle ID MJAppId = [NSBundle mainBundle].bundleIdentifier

Zhanghua123:~ root# cycript -p live4iphone
cy# @import mjcript
{}
cy# [Nsbundle mainBundle]
throw new ReferenceError("Can't find variable: Nsbundle")

一步一步實現iOS微信自動搶紅包(非越獄)

找到CMessageMgr.h和WCRedEnvelopesLogicMgr.h這兩文件，其中我們注意到有這兩個方法：- (void)AsyncOnAddMsg:(id)arg1 MsgWrap:(id)arg2; ，- (void)OpenRedEnvelopesRequest:(id)arg1;。沒錯，接下來我們就是要利用這兩個方法來實現微信自動搶紅包功能。其實現原理是，通過hook微信的新消息函數，我們判斷是否爲紅包消息，如果是，我們就調用微信的打開紅包方法。這樣就能達到自動搶紅包的目的了。
