入参1是json数据，入参2是uuid，入参3，4是固定的（本机固定，不同设备未测试）。输出做个base64就是qdata

运行多次后，发现结果不变，和frida调用表现不一致。这是因为unidbg的种子是固定的，导致生成的随机数序列是固定的，进而导致结果是固定的。
固定随机数
1240
ida跳转到0x5ead
1240
1240
innoSecure
1240
1240
1240
1240
innoSecure函数有900行左右，把很多东西都塞到这里实现了，看起来又臭又长。
其中有个arc4random函数，一看就是用于生成随机数的，hook它将随机数固定。
// fail
public void hook_libc() {
IHookZz hookZz = HookZz.getInstance(emulator);
hookZz.wrap(module.findSymbolByName("arc4random"), new WrapCallback() {
@Override
public void preCall(Emulator emulator, HookZzArm32RegisterContext ctx, HookEntryInfo info) {
}
@Override
public void postCall(Emulator emulator, HookZzArm32RegisterContext ctx, HookEntryInfo info) {
ctx.setR0(1);
}
});
}
public static void main(String[] args) {
Qutoutiao test = new Qutoutiao();
test.hook_libc();
test.call_secure();
}
1240
然后就报错了，跳转过去看看。
1240
这个函数没有实现，这我也不会啊。。
1240
换个思路，直接patch调用arc4random函数这条指令，将r0设为1，相当于每次随机数函数的返回值为1。
public void patch() {
// mov r0,1
emulator.getMemory().pointer(module.base + 0x77e8).setInt(0, 0x0001f04f);
}
public static void main(String[] args) {
Qutoutiao test = new Qutoutiao();
test.patch();
test.call_secure();
}
1240
结果出来了，之后的逆向将基于此结果。
固定随机数的好处就是每次输出都不会变，方便分析。而且我们能一眼看出哪个是随机数，做到心中有数。
分析输出
真正开始逆向之前看看输出的组成方式，base64解码看看输出。
1240
可以大致看出输出由3部分组成，各部分用.连接，第1部分是32位字符串，应该是个MD5；第2部分是base64之后的字符串，第3部分是乱码，应该是加密后的数据。
base64解码第2部分看看
1240
比较容易构造。
第3部分的长度是147，比较奇怪，因为json数据的长度是125。AES，DES，RC4加密后都和这个长度搭不上边，可能还拼接了其他东西。
逆向
1240
一个比较容易看出来的就是MD5，x22对应update方法，x23对应final方法。hook看看
public void hook_MD5() {
IHookZz hookZz = HookZz.getInstance(emulator);
hookZz.enable_arm_arm64_b_branch();
hookZz.wrap(module.base + 0x35EC + 1, new WrapCallback() {
@Override
public void preCall(Emulator emulator, HookZzArm32RegisterContext ctx, HookEntryInfo info) {
Pointer input = ctx.getPointerArg(1);
byte[] inputHex = input.getByteArray(0, ctx.getR2Int());
Inspector.inspect(inputHex, "Input(x22)");
}
@Override
public void postCall(Emulator emulator, HookZzArm32RegisterContext ctx, HookEntryInfo info) {
}
});
hookZz.wrap(module.base + 0x3E10 + 1, new WrapCallback() {
@Override
public void preCall(Emulator emulator, HookZzArm32RegisterContext ctx, HookEntryInfo info) {
Pointer output = ctx.getR1Pointer();
ctx.push(output);
}
@Override
public void postCall(Emulator emulator, HookZzArm32RegisterContext ctx, HookEntryInfo info) {
Pointer output = ctx.pop();
byte[] outputHex = output.getByteArray(0, 16);
Inspector.inspect(outputHex, "Output(x23)");
}
});
hookZz.disable_arm_arm64_b_branch();
}
public static void main(String[] args) {
Qutoutiao test = new Qutoutiao();
test.patch();
test.hook_MD5();
test.call_secure();
}
1240
1240
进行了两轮MD5，每轮的第1个调用是真实数据，其他是算法填充。cyberchef验证是标准MD5。
可以看到第二轮的MD5结果就是最后输出的第1部分。而第二次MD5输入的前面部分则是最后输出的第3部分的后面部分。
1240
再看看第二轮MD5输入的后面32字节。可以看出偶数位拼接起来就是第一次MD5的输出，而奇数位反向拼接起来则是原始输入的第二个参数（去掉-符号）。
1240
至此，第1部分的计算方式已经出来了。
接下来先看看第3部分的后面部分的计算方式。
1240
1240
1240
这个是AES的常量，从代码可以看出是CBC，进行了13+1=14轮操作，所以应该是AES-CBC-256加密，key的长度位32。
由于实现的时候把大部分代码都写在一起了，没有一个函数入口来hook，得到输入，key，iv。因此只能分析代码，下断点看看对应的变量。
1240
由于v112初始值为0，所以先进入else语句
1240
这里是输入与iv进行异或操作的地方，下断点看看。
1240
emulator.attach().addBreakPoint(module.base+0x7F84);
1240
1240
由于之前固定了随机数，一眼就看出它是随机数，不需要继续往下分析了
1240
从代码也能看出。
然后是key
1240
1240
同样下断点
emulator.attach().addBreakPoint(module.base+0x7F9C);
1240
1240
有了输出，key，iv，尝试解密看看
1240
说明找的是对的。
固定住uuid和iv，更换输入的第一个参数，其他部分不变。此时有个取巧的方案，固定uuid和iv，这样剩下的就不用分析了。
继续分析key的来源
1240
其中要关注的变量有v206, v191，还有个常量innoSecureParityTable256
下断点看看
v206
1240
之前讲过它的构成了。
v191
1240
更换输入后发现它是不变的。
然后根据代码实现一下即可。

接下来是找输出的第3部分的前面部分，共19个字节。
1240
先分析后16字节
1240
1240
v205是iv
1240
v208是第一次MD5的结果。
1240
然后实现一下即可
v201 = bytes(map(lambda x, y: ~(x ^ y) & 0xff, s0, iv))
接着分析前3个字节。
先看第1，第3个字节。
1240
v201正是后面的16字节，然后实现一下即可。
def calc_var(v201):
v43 = 15
v42 = 0
for v43 in range(15, -1, -1):
v45 = v201[15-v43]
v42 |= (((v45 >> 3) & 1) << v43)
print(v42)
print(hex(v42))
v47 = 16
v49 = 0
v46 = 0
v48 = 0
while 1:
v50 = v47 - 1
v51 = ((v42 >> v47) ^ (v42 >> (v47 - 1))) & 1
if v49 > 7:
v48 |= (v51 << v50)
else:
v46 |= (v51 << (v47 - 9))
v49 += 1
v47 -= 1
if not v50:
break
print(v46, hex(v46))
print(v48, hex(v48))
return v46, v48
最后分析第2个字节。
1240
同样根据代码实现即可
n2 = -sum(v201) & 0xff
全部分析完了，最后把代码整合一下即可
