iOS逆向-支付宝基金之统计实时收益

536人阅读  评论(0)

前言:现在全民买基的情况下,女票也买了一些,对于买基新手来说,总是想打开支付宝看看到底今天是赚是赔,女票说支付宝收益第二天才显示太慢了,要是能打开直接看到收益就好了,作为一个合格的程序员,怎么能不满足这小小的需求?写篇记录一下过程。

效果图:

原理:监控请求接口,获取需要的基金数据,根据持有的每个基金实时净值,计算实时收益,弹窗显示计算的实时总收益;

开始

工具:

  1. CrackerXI+
  2. 爱思助手
  3. Class-dump
  4. MonkeyDev

一、砸壳

(一)越狱机安装CrackerXI+
  1. 在cydia 中添加 源地址 http://cydia.iphonecake.com 或者 http://apt.cydiami.com ,添加成功后,在cydia中搜索CrackerXI+并安装。
  2. 打开CrackerXI+,在settings中设置CrackerXI Hook为enable

(二)砸壳

  1. 先在App store下载安装蚂蚁财富,然后打开CrackerXI+选中蚂蚁财富,然后选择 YES,FULL IPA 开始砸壳
  2. 砸壳完毕会显示砸壳后IPA的路径的路径/var/mobile/Documents/CrackerXI/
  3. 打开爱思助手或者用ssh链接都可以,按照路径导出ipa包就可以了。


终端输入以下命令 可以查看有么有砸成功:

otool -l 可执行文件路径 | grep crypt


cryptid 0 砸壳成功

二、安装MonkeyDev

git地址:https://github.com/AloneMonkey/MonkeyDev

准备

  1. 安装最新的theos
	sudo git clone --recursive https://github.com/theos/theos.git /opt/theos
  1. 安装ldid(如安装theos过程安装了ldid,跳过)
	brew install ldid

安装

你可以通过以下命令选择指定的Xcode进行安装:

  sudo xcode-select -s /Applications/Xcode-beta.app

默认安装的Xcode为:

  xcode-select -p

执行安装命令:

  sudo /bin/sh -c "$(curl -fsSL https://raw.githubusercontent.com/AloneMonkey/MonkeyDev/master/bin/md-install)"

卸载

  sudo /bin/sh -c "$(curl -fsSL https://raw.githubusercontent.com/AloneMonkey/MonkeyDev/master/bin/md-uninstall)"

更新

  sudo /bin/sh -c "$(curl -fsSL https://raw.githubusercontent.com/AloneMonkey/MonkeyDev/master/bin/md-update)"

安装成功效果图:

三、逆向分析

(一)Class-dump导出头文件

class-dump -H [.app文件的路径] -o [输出文件夹路径]

导出如下:

(二)新建monkeyDev工程

把IPA放入工程指定目录
运行程序分析界面:

页面是一个WKWebView,我们只需要获取H5页面请求后的数据就可以了。然后我们用safari开发模式看一下页面,结果在控制台看到了接口打印数据,正是我们需要的数据,线程回调结果:


NSOperation结合NSURLConnection,搜索头文件,找到一个 DTURLRequestOperation文件,继承了NSURLConnectionDataDelegate, NSURLProtocolClient, NSURLSessionDataDelegate协议,还包含了request和response,一看就知道是和wkwebview请求有关,尝试拦截一下。


看到可以拦截到WKWebview的请求,下一步从众多请求中找出我们需要的请求数据就可以了。

四、Hook

线程名称包含在请求头中,根据线程名筛选需要的请求结果:

// 自选关注的基金信息
com.alipay.wealthbffweb.fund.optional.queryV3
// 持有的基金信息
com.alipay.wealthbffweb.fund.commonAsset.queryAssetDetail

筛选要求获取的请求结果

// 获取请求返回数据
+(void)hookWithOperation:(DTRpcOperation *)operation{
    @try {
        NSDictionary *allHTTPHeaderFields = operation.request.allHTTPHeaderFields;
        NSString *type = allHTTPHeaderFields[@"Operation-Type"];
        
        
        if([type isEqualToString: @"com.alipay.wealthbffweb.fund.optional.queryV3"]){
            // 计算收益
            [self calculateIncomeWithOperation:operation];
        }else if([type isEqualToString: @"com.alipay.wealthbffweb.fund.commonAsset.queryAssetDetail"]){
            // 获取份额
            [self getFundSharesWithOperation:operation];
        }
    } @catch (NSException *exception) {
        NSLog(@"error:%@", exception);
    }
}


#pragma mark - holdingMap

    static NSString *path;

    dispatch_once(&onceToken, ^{

        NSString *documentsDirectory = [paths objectAtIndex:0];

    }
    fundSharesDic = dic;
}

/// 读取本地保存的份额
+ (NSString *)getFundSharesWithFundCode:(NSString *)fundCode { //fundCode 基金代码

    }
