[原创]一道简单的ollvm算法题还原

本题出自看雪3W班 12月ollvm题
得益于Unicorn的强大的指令trace能力,可以很容易实现对cpu执行的每一条汇编指令的跟踪,进而对ollvm保护的函数进行剪枝,去掉虚假块,大大提高逆向分析效率。请分别使用Unidbg和Stalker引擎完成对该app中的jnicheck函数的trace跟踪,并简单分析该apk逻辑,找出flag。
题目要求使用unidbg对ollvm加密后的算法进行还原。需要调用的native函数中,又会使用CallStaticBooleanMethodV调用另一个native函数。当时unidbg本身好像不支持这种方式,需要对unidbg代码进行部分修改之后才能正确进行模拟执行。
可以模拟执行之后,简单的思路就是使用unidbg进行trace找出哪些代码分支是可能被执行的,哪些条件分支是可以被优化掉的,之后对so进行patch,再使用ida进行分析。
本题主要有两个知识点,第一是对unidbg本身的修改使得能够支持一些原本不支持的场景,第二是对函数进行trace后patch源文件减少ollvm的干扰。
DvmObject.java 中新增initArgs,用于初始化调用参数
DalvikVM64.java中修改CallStaticBooleanMethodV的hook代码,用于支持函数直接初始化调用参数后直接修改pc来call,通过R0来区分判断是否是这种方式调用.
MainActivity.java 主要的模拟调用代码
不太懂ollvm怎么剪枝,通过观察发现ollvm生成的很多块都有一些特征,于是直接通过一些简单的条件来把一些块末尾跳转直接改成无条件跳转.
条件是:1.这个块在执行时的下一个块是唯一的 2.块的结尾两条汇编指令符合一定特征
然后随便用几个输入调用一下函数,让尽可能多的块被执行
之后把patch后的so保存下来.使用IDA进行分析
Java_com_kanxue_crackme_MainActivity_jnicheck的反编译结果如下
可以看到返回值主要取决于sub_28EB8
sub_28EB8实际上就是去调用Java_com_kanxue_crackme_MainActivity_crypt2
Java_com_kanxue_crackme_MainActivity_crypt2的返回值取决于sub_22390,通过调试可以知道它的参数就是我们的输入的字符串后面拼接666
sub_22390中还是有大量的ollvm混淆后的分支,说明我们之前的几个错误输入都没有进入到里面执行,因此我们需要想办法构造一个输入来进入到里面进行执行,我们的输入首先被传入了sub_19A60中
很显然是一个base64的函数,通过调试可以知道之后的结果通过strcmp与WFVlNjY2进行比较来判断是否进入下面的分支中运行.WFVlNjY2解码得到XUe666,因此我们在模拟调用时以XUe作为参数再次运行后对so进行patch,可以发现XUe就是正确的答案,同时之前一些分支的混淆也被去除了
sub_22390
去除混淆后,可以发现sub_22390的逻辑很简单,就是返回输入的值经过base64与一个常量比较的结果.至此整个逻辑分析完毕,正确答案是XUe
由于本题的ollvm混淆比较有特征性,所以才能够简单的去除掉。
