[Android 原创] 某虚拟定位APP从破解到原理分析

工具环境
ida7.0
iphone 6
ios 10.2
0x00:基本情况
1. 该app可以修改模拟手机地理位置(gps、基站、WIFI),拥有全局定位、指定应用定位、模拟扫街等功能,只能在已越狱的IOS系统上使用,安装须要用到Cydia,安装后主要分为插件与主程序两个部分,主程序负责与用户交互,插件主要实现了修改地理位置的功能。在Cydia插件安装目录可以找到它释放的xxtweak.dylib文件,拷贝出来后面做详细分析。
2. 程序运行后如果不是vip用户是不能使用修改定位的功能,如下:

1

1

2

0x01:保护机制分析
1. 将手机设置好代{过}{滤}理,启动app登录,用抓包工具获取数据包做分析,发送到服务器的数据与服务器返回的数据都是加密的,如下图:

3

3

2. 通过动态调试主app来寻找突破口,主app通过sysctl来做反调试,先编写一个tweak来过掉反调试。这个代码网上很多,如下:
[C] 纯文本查看 复制代码
static int (*orig_sysctl)(int * name, u_int namelen, void * info, size_t * infosize, void * newinfo, size_t newinfosize);
static int my_sysctl(int * name, u_int namelen, void * info, size_t * infosize, void * newinfo, size_t newinfosize){
        int ret = orig_sysctl(name,namelen,info,infosize,newinfo,newinfosize);
        if(namelen == 4 && name[0] == 1 && name[1] == 14 && name[2] == 1){
                struct kinfo_proc *info_ptr = (struct kinfo_proc *)info;
        if(info_ptr && (info_ptr->kp_proc.p_flag & P_TRACED) != 0){
            NSLog(@"[AntiAntiDebug] - sysctl query trace status.");
            info_ptr->kp_proc.p_flag ^= P_TRACED;
            if((info_ptr->kp_proc.p_flag & P_TRACED) == 0){
                NSLog(@"[AntiAntiDebug] trace status reomve success!");
            }
        }
        }
        return ret;
}

3. 将app放入ida中反编,用登录抓包获取到的信息中关键字来查找字符串定位到组合参数的地方,组合后格式如下:
[Asm] 纯文本查看 复制代码
{
        "data":"{
"clientid":"4092f7a187943eff48d1c4b827b5f53c",
"username":"xxxxx",//用户名
"password":"xxxxxx"//密码
}",
        "header":{
        "uptime":"1540607913",
        "sysapi":"10.2",
        "model":"iPhone 6",
        "systype":"1",
        "vercode":"15.13",
        "uuid":"DA148217C2491937"
    }
}

然后将组合后的代码用AES加密发送到服务器代码如下:

    "username":"xxxx",//用户名
    "vip":0, //是否为vip用户
    "expiretime":0 //会员过期时间
}

5. 整个登录过程就分析完成了,主要用到了AES加密算法。
0x02:破解思路
1. 通过上面登录过程的分析,根据上面数据格式可以直接改vip与expiretime的值就能成功破解成会员用户,如下图 :

2. 将服务器返回的值存入.plist文件后,程序会调用-[TXYTools isCanOpen]方法读取文件判断是否为vip,代码如下:
[Asm] 纯文本查看 复制代码
  bool __cdecl -[TXYTools isCanOpen](TXYTools *self, SEL a2)
{
  void *v2; // x0
  void *v3; // x0
  void *v4; // x20
  void *v5; // x0
  void *v6; // x23
  void *isVIP; // x19
  id v8; // x0
  void *v9; // x0
  void *v10; // x23
  void *v11; // x0
  void *v12; // x20
  void *v13; // x0
  void *v14; // x23
  void *authValue; // x21

  v2 = objc_msgSend(&OBJC_CLASS___NSUserDefaults, (const char *)&unk_188A615FA);
  v3 = (void *)objc_retainAutoreleasedReturnValue(v2);
  v4 = v3;
  v5 = objc_msgSend(v3, (const char *)&unk_188A60093, CFSTR("isVIP"));
  v6 = (void *)objc_retainAutoreleasedReturnValue(v5);
  isVIP = objc_msgSend(v6, (const char *)&unk_188A5DF6B);
  objc_release(v6);
  objc_release(v4);
  v8 = ((id (__cdecl *)(TXYTools_meta *, SEL))objc_msgSend)((TXYTools_meta *)&OBJC_CLASS___TXYTools, "sharedTools");
  v9 = (void *)objc_retainAutoreleasedReturnValue(v8);
  v10 = v9;
  v11 = objc_msgSend(v9, "loadSetDictForPath:", CFSTR("/var/mobile/Library/Preferences/com.txy.TxyNew.plist"));
  v12 = (void *)objc_retainAutoreleasedReturnValue(v11);
  objc_release(v10);
  v13 = objc_msgSend(v12, (const char *)&unk_188A60093, CFSTR("authValue"));
  v14 = (void *)objc_retainAutoreleasedReturnValue(v13);
  authValue = objc_msgSend(v14, (const char *)&unk_188A5DF6B);
  objc_release(v14);
  NSLog(CFSTR("user = %ld"));
  NSLog(CFSTR("isVIP = %ld"));
  objc_release(v12);
  return (signed __int64)isVIP > 0 && (signed __int64)authValue > 0;
}

3. 第一是可以通过修改服务器返回值做破解,第二是通过hook方法isCanOpen来做破解。代码如下 :
[Asm] 纯文本查看 复制代码
%hook TXYTools
- (BOOL)isCanOpen
{
return YES;
}
%end

破解成功后可以正常使用功能,如下图所示 :
