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:
- CrackerXI+
- 爱思助手
- Class-dump
- MonkeyDev
一、砸壳
(一)越狱机安装CrackerXI+
- 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。
- 打开CrackerXI+,在settings中设置CrackerXI Hook为enable
(二)砸壳
- 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
- 砸壳完毕会显示砸壳后IPA的路径的路径
/var/mobile/Documents/CrackerXI/
- 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
- 安装最新的theos
sudo git clone --recursive https://github.com/theos/theos.git /opt/theos
- 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

NSString *type = allHTTPHeaderFields[@"Operation-Type"];

// 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) {
