这个软件时间比较久了,我就不放链接了,主要是学习思路,XX中控v1.3

1、检查软件

拖到PEinfo里面查壳

PyInstaller打包,py软件无疑,接下来就解包就完事了,下载 pyinstxtractor.py 用python解包,注意python版本要一致才能解出来PYZ里面的文件

运行软件查看特征

软件跑起来没啥特别的,点击注册,然后输入个假码,可以看到提示了一个弹窗,输入正确的激活码

没啥有用的消息,开搞

2、破解思路

刚开始打算动态调试找关键点的,但是之前的软件也是动态调试踩了坑,在虚拟机的海洋里面遨游,找不到关键点,但是发现了个神奇的东西,我x64dbg打开就被关掉了,第二次才能打开,看来这个软件是有反调试的(后面检查发现不止x64dbg,x32dbg,CheatEngine,IDA都被检测了)。但是这里就稍微差点了,检测应该开个单独的线程持续检测,但是作者在检测了一次之后就停止了检测,所以第二次才能打开。而且文件有完整性校验,改了之后文件sha256对不上他会云端下载个新的替换了。

3、开始破解

开始开包,包打开长这个样子

主函数一点有用的都没,大致可以猜出来这个inlet应该就是程序入口(至于原因自己多拆几个包就知道了),可以看到程序运行了start,从runner包里面导入的,去pyz里面找了找runner包,发现没有,那更寄了,runner可能是一个pyd,返回这个exe的目录,可以在目录里面发现resources,在里面找到了我们想要的runner.pyd。已知pyd不可逆(为python代码),从源代码找蛛丝马迹的方法失败,看下一步了

动态调试

已知动态调试被检测了,而且找不到关键点

那我们跳过动态调试,直接开始静态

打开大姐姐(IDA),拖入runner.pyd,啥也看不出来,关闭大姐姐,开VAN笑,我能这么简单就被劝退吗。继续研究,先找几个函数看看特征,发现里面的函数基本一致,但是里面的字符串是明文的,函数功能基本看不出来,可以发现程序调用的py的函数名字,只能慢慢跟流程,看看程序都干了什么

在这里我们发现了几个比较关键的点,一个加密库,(至于为什么不是前面的sha_256和RSA(rsa加密是在明文里面找到的resources\certifi\cacert.pem)因为sha不可逆,不会用来当请求传输,RSA我已经试过了,不是这个)。两个http请求,一个base64字符串(实际是秘钥,这里先假装不知道干嘛的)。

现在看着一下就找到关键点了,实际这个东西我前后研究了一周多才找到这些关键点,所以做逆向最重要的就是耐心和细节。善于发现代码里的蛛丝马迹

柳暗花明又一村

发现了http请求那就转换思路,我们抓包改响应,伪造正确响应返回。现在转向第二战场HttpDbgPro(为啥用HttpDbgPro不用之前的小黄鸟了,因为小黄鸟有缺陷,漏包,很多HttpDbgPro能抓到的包小黄鸟抓不到,虽然小黄鸟的重写脚本之类的很好用很方便,但是一个抓包工具漏包那我是不能接受的,如果是使用姿势有问题,希望能提供正确方法让他不漏包)

打开HTTPDbgPro,设置过滤,重新运行软件,可以看到软件在启动的时候有两个请求,一个GET一个POST,这里先不管,看看登录发送了什么。点击登录,发现两个POST请求,根据请求链接猜测一下一个是登录一个是心跳(实测过了verify就是心跳,几分钟发一次的)

但是这里的请求内容和响应内容是加密的,先分析下加密后的内容,看起来像是BASE64,解码一下试试发现不对,但是每个请求不管是请求体还是响应体都是‘gAAAAABm’开头的,看起来是自定义加密,我们喂给GPT看看

哦豁了,GPT直接识别出来加密方式了

那我们继续问问秘钥有什么特征

好了,已知秘钥带等号,那就简单许多了,直接去IDA里面搜索=

成功找到了一条,去python里面写代码解密一下

An error occurred during decryption:解密失败了,先不担心,找他对应的请求,发现请求是/multiple_files_value_verify那解密这个里面的请求体和响应体呢

请求体

这下就能确定了,加密方式就是Fernet ,只是每条请求的秘钥可能不一致,去其他pyd里面寻找总共是找到了6条key

我上面已经把所有的请求和密钥全部对应起来了。XX助手是作者的另一个软件免费的,帮了很大的忙,接下来先用HTTPDbgPro伪造响应,我们先把XX中控的登录响应解密,是一个txt文本

假码登录请求体

{"code": "123", "uuid": "03000200040005000006000700080009", "ip": "", "requests_times": "1", "num": "2569", "sign": "9f468242fce1c30d780913a1cf0afaa6fdb80fce24c741c8d5d2f847ee628cdd"}

假码登录响应体

2|无效注册码

这样伪造有点难,我们去XX助手抓下包(因为xx助手也是作者的免费软件,但是作者送了一个激活码用来登录,我们直接解下xx助手的响应),注意这里的xx助手的登录加密秘钥和xx中控不一致,解码之后响应如下

XX助手响应体(登陆成功)

1|2029-5-21 00:00:00|1|9

我们吧这个响应用XX中控的秘钥重新加密,然后在HttpDbgPro伪造响应(Fernet 加密每次加密后的文本不一定一样,不用在意)

这会再去登录,可以发现我们现在的状态已经变成已激活了

但是过段时间就掉了,变成无效注册码,软件肯定有心跳,之前也说了两条验证,心跳和登陆用的是同一个秘钥,直接用登陆的内容返回就行

我们把心跳也伪造了,这样就不会掉线了,然后开始测试软件功能

可以看到手机已经能正常连接了,但是开启投屏之后什么都没有投出来,操控是可以使用的,刚开始以为是软件问题,去XX助手(免费的)上面试了试发现可以投屏,那我们再观察一下登录之后还干了什么

可以看到有个GET请求,但是无响应,刚开始我以为这是上传用户信息的,我们去XX助手(免费版)看看有没有类似的,在免费版上我们看到了类似的请求,但是是有响应的,猜测可能是远程代码或者远程变量,如下

远程代码响应

咱们吧代码重新加密回去,在HttpDbgPro上伪造响应

可以看到投屏出来了,控制也没有问题。难道这个作者两个软件是同一个云端代码吗,我是报怀疑态度的。但是我没法去拉XX中控的云端代码,这需要一个真卡去抓请求

注:因为我没多的手机,无法测试多个手机的情况。经供参考

4、补充

你以为到这里就结束了?,实则不然。这个免费版的代码和收费版的云端代码通用在我这里一直是一个心事,难道除了买真卡就没办法去获取这个收费版的代码了吗。

回收伏笔

记得我们上面说的完整性校验吗,校验不通过会通过http://47.119.173.20:18003/download_file下载,既然他要下载文件,那我们伪造一个去下载云端代码的,触发下载很简单,去resources目录下删掉setting.pyd就可以触发下载了。http://47.119.173.20:18003/download_file请求是明文的,不需要解析。解析下XX中控的远程代码请求,如下

我们稍加修改,把目录和文件名字改成我们要的远程代码mjpeg_tool.py然后随便用个工具进行GET请求。诶,作者最谨慎的点害了他呀

云端代码被我们下载下来了,至此,分析全部结束。

但是实际上这个玩意的代码和免费版的是一样的,除了日期
