【iOS逆向】iOS可执行文件权限签名

发表于 更新于 分类于

iOS中使用entitlement文件来描述可执行文件的权限，例如，当我们在Xcode中勾选了推送的权限，就会看到生成了一个entitlement文件，里面包含下面内容

1
2
<key>aps-environment</key>
<string>development</string>

如果勾选了Sign With Apple，会出现

1
2
3
4
<key>com.apple.developer.applesignin</key>
<array>
    <string>Default</string>
</array>

只有配置了对应的权限声明，并签名到可执行文件中，程序才有权限执行对应的功能，例如如果我们没有加上Sign With Apple，则苹果登录相关的接口会失败

Entitlement

iOS中可执行文件会包含entitlement来声明可执行文件有用哪些权限，默认的iOS开发的应用程序的权限有限，例如只能访问沙盒数据，不能访问系统目录，不能访问其他App，而系统程序却可以，主要差别在于可执行文件签名的权限，系统程序拥有更高的权限，例如SpringBoard

签名

在Mac上，我们可以通过ldid工具，对可执行文件的权限重新签名，也可以导出可执行文件的entitlement描述

0. 安装ldid

1
brew install ldid

1. 导出entitlement描述

使用ldid，导出可执行文件SpringBoard的权限到SpringBoard.entitlements

1
ldid -e SpringBoard > SpringBoard.entitlements

2. 重新签名entitlement

把权限SpringBoard.entitlements签名到可执行文件TestTool中

1
ldid -SSpringBoard.entitlements TestTool

此时，TestTool就拥有跟SpringBoard一样的执行权限

3. 使用codesign签名

除ldid外，也可以通过codesign进行签名，codesign就有一个entitlement参数

1
codesign -d --entitlements TestTool.entitlements TestTool

实践

1. 导出SpringBoard程序的权限

SpringBoard应用位于/System/Library/CoreServices/SpringBoard.app，我们先把他拷贝出来

1
scp root@xx.xx.xx.xx:/System/Library/CoreServices/SpringBoard.app/SpringBoard ~/Desktop/SpringBoard

通过上面的ldid命令导出得到entitlement，如下

可以看到，包含的权限非常多，苹果并没有给出这些权限的说明，通常我们直接用就行了，这里有一篇文章做一些整理iOS Entitlement分析

1. 导出默认iOS应用程序的权限文件

新建一个iOS工程，开启推送和Sign With Apple，编译，得到xxx.app，拿到可执行文件xxx，使用ldid导出得到

其中get-task-allow为允许其他进程（如调试器）附加到您的应用程序。我们自己编译的App可以进行调试，而商店下载的App没有该选项

相比之下，默认的App权限少得可怜，我们可以吧SpringBoard的权限SpringBoard.entitlement签名到我们的程序XXX中，这样就可以有更多的操作权限了，例如访问沙盒外的路径

ldid -SSpringBoard.entitlement XXX
