实战:干掉高德地图7.2.0版iOS客户端的反动态调试保护

直接hook sysctl本身

嗯嗯 试了张总WTFJH的工具集 里面的init_sysctl_hook() 安装后app打开就闪退。。报错如下

May 5 18:31:04 ahahaha JCB[448]: MS:Notice: Loading: /Library/MobileSubstrate/DynamicLibraries/antisys.dylib
May 5 18:31:05 ahahaha ReportCrash[449]: MS:Notice: Injecting: (null) [ReportCrash] (847.21)

May 5 18:31:05 ahahaha ReportCrash[449]: ReportCrash acting against PID 448
难道是反反反动态调试?哈哈

那玩意我只测试了ptrace,禁用下sysctl试试。目前没空修

看一下CrashReport,程序是在哪里出错的…

应该是我的实现机制。有空了改成低层实现吧

我试了也是这样

各位大大好,我看完书之后,对于Cydia上的某个app的功能很兴趣,但是动态调试的过程中,发现出现错误
Attaching to process xxx…
Segmentation fault: 11

大概知道是反动态调试的关係,查了许久之后找到狗神的此篇文章:http://www.iosre.com/t/7-2-0-ios/770
但是裡面的第二步骤,我就失败了,因为使用指令ps -e之后只有看到
//Applications/XXX.app/XXX

我使用Cycript -p TargetApp他也只是卡在loading一直无法进入操作
所以我无法去找到bundle path的可执行档案用LLDB去启动,请问还有解吗?

我为了测试证明不是debugserver的问题,有去试过app store上的apps 还有cydia上的app例如activator,全部都可以被动态调试,就只有我有兴趣的cydia app不能调试QQ
如果有需要知道是哪个app再跟我说,因为我怕违反留言规则,被删留言

App名不敏感,你直接发个新帖,然后在帖子里详细描述一下问题吧

好的大大!

有一个地方没看明白,“ptrace的调用者位于0xdbd19 - 0xd1000 = 0xAD19处”, 而截图显示代码调用处地址是0xAD18,差了1。望回复,谢谢。

我自己的理解,不一定对:每一条汇编指令,都是有长度的,在此处,0xAD18和0xAD19,都是MOV R0, R4

大佬大佬。你这个问题解决了吗?我也遇到和你一样的问题,一筹莫展啊

解决了话给点思路。多谢了!

请问大佬,如何确定是main函数呢

看到了关键词UIApplicationMain

明白了,多谢

大神解决没有?调试某宝(v10.1.52),遇到同样的问题,怎么破?
