[原创]某口算部分算法还原思路(禁止用来欺负小学生)

前言: 本文仅为了交流学习，提高逆向对抗的水平，更好的防护APP。
版本:应用商城最新
不提供Frida调用脚本，不提供成品算法，仅记录分析过程。如有侵权，请联系我下架，但是我更希望厂商能在不断对抗中进步学习进步自己的产品。

frida检测 spwan注入

进行入参的字符串分析

通过字符串出现的地址找到处理这个字符串的地址

定位到这个函数，发现是个基础函数，通过trace找一共调用了几次

写一个frida脚本进行hook，看处理了什么

发现算法直接被还原出来了，但是到这里还没有结束，让我们看看厂商创新的点

接下来目标变得非常简单，看这些字符串哪里来的

首先是简单的字符串拼接

大家可以根据打印日志尝试，进行还原

简单的字符串拼接我就不讲了:

这里有一串位置数字

找一下：

142401346320179532017943221662728816116777216143261965096053842881612216627182881616157632309605384288161611428816154288161612619650288161524802692576323014960538414480269248026927144161488641828816161147144161488643201794576323032017955763230288161521169605384288161552881615143355443219288161532881615214576323028816155480269219167772161414288161611416721288161541428816153433554432240134657632307288161614

的来源

根据入参数推算大概率和第三个参数有关系 -28673

看一下调用了哪些函数，找一下线索

发现调用了大量rand，在这里我推测和第三个入参，以及ctf中出现的伪随机数有关系

从内存中找一些线索

1324013443201793320179222216625288161167772161322

找到第一次出现的地方

发现在这个函数里

发现只是一个复制用的系统库函数

从函数头找上一次调用点

在此处发现线索

搜索内存写入的地址

7d09097130 [libRequestEncoder.so!67130] stp x8, x9, [x19, #48] ; r[X8=0xb400007c95400b01 X9=0xb400007c95400b17 X19=0xb400007c95400ac0] w[]

通过ida动静态结合

向上寻找上一层调用

再次向上追溯

发现是num_put的第二个参数

还处于系统库之中

找到疑似计算的地方

向上追溯一层堆栈，瞬间清晰明了，之前的几次append也被发现了

那么我们直接找增加随机数的这个append前面的逻辑即可

倒数第三次

根据log就可以还原

理所当然的只有一次出现 我们只需要跟踪

7d09096b88 [libRequestEncoder.so!66b88] csel x1, x10, x9, eq ; r[X10=0xb400007c95400c71 X9=0xb400007c7347c880] w[X1=0xb400007c72e0e900]

根据上下文判断(tst w8 0x1) x9会赋值给x1 追踪x9赋值的地方

发现在栈里 进一步跟踪栈的值

向上追溯发现大量字符串 是目标的

找到随机串第一次出现的地方

真口算

hook入参，出参，即可分析出

给厂商的建议：

增加混淆，把常规算法(md5)做一些魔改，哪怕魔改几个IV也会有出奇的作用，做一些反trace的检测

多增加一些浮点数运算，增大模拟调用难度

禁止拿去欺负小学生

function hook_dlopen(soName = '') {
    Interceptor.attach(Module.findExportByName(null, "android_dlopen_ext"), {
        onEnter: function (args) {
            var pathptr = args[0];
            if (pathptr !== undefined && pathptr != null) {
                var path = ptr(pathptr).readCString();
                if(path.indexOf('libmsaoaidsec.so') >= 0){
                    ptr(pathptr).writeUtf8String("");
                }
                console.log('path: ',path)
            }
        }
    });
}

                var path = ptr(pathptr).readCString();
                if(path.indexOf('libmsaoaidsec.so') >= 0){
                    ptr(pathptr).writeUtf8String("");
                }
                console.log('path: ',path)
            }
        }

你好，麻烦问一下是如何trace出来流程保存本地的，是unidbg吗，另外您的apk版本是多少，我目前也是卡在您提到的这个长数字中，我固定了时间戳，他结果也是固定了，所以我想跟你一样保存到一份日志到本地来。

用STL标准库是降低逆向难度吧，特别是用共享cpp库的，逻辑清晰明了，那个 std::string的 append追加函数其实是operator +被优化成了append操作。

关键的时间戳生成没有分析出来。纯算的话这里可以阻挡一些人，但是阻挡不了unidbg

其实没有什么可以讨论的，就是一个自写的时间戳生成，拓展成几百位的一个字符串，这个字符串和之前的path路径拼接，几轮标准的MD5

unidbg生成可以看xiaoyuan_unidbg

就是这个几百位的一个字符串 让我很迷茫，其他都分析得差不多了

你按照so的逻辑一步一步跟，就能还原出来了，这纯体力活

你看楼主的sub_65794伪代码：

time(&timer);
timer = (timer + a2) / 60

就一直跟着

timer

几百位的字符串，这个都是基于这个变量来的。

我给你看下我iOS还原出来的：


基本逻辑都是这样

是这样的，但是string在内存里结构体的体现是有一定的难度的，假如没有符号，感觉分析会难一些，对于我这个trace工具确实是有一些难度

您好，不是unidbg，是直接在真机上执行的，自己写的一个trace，注入可以参考我上一篇帖子，用的zygisk注入的，如果有需要可以联系我，我给你固定你的值帮你trace一份

自己写的一个trace 速度是unidbg的60倍左右
