### 0x01.Hook #### 1.Hook代碼 ```c #include <stdio.h> #include <stdlib.h> #define MIB_IP_ADDR 170 #define MIB_HW_VER 0x250 #define MIB_CAPTCHA 0x2C1 int apmib_init(void) { return 1; } int fork(void) { return 0; } void apmib_get(int code, int *value) { switch(code) { case MIB_HW_VER: *value = 0xF1; break; case MIB_IP_ADDR: *value = 0x7F000001; break; case MIB_CAPTCHA: *value = 1; break; } return; } ``` #### 2.交叉編譯成mips ```shell mips-linux-gnu-gcc -fPIC -shared success.c -o success.so ``` #### 2.Qemu加載hook代碼模擬固件 ```shell sudo chroot . ./qemu-mips-static -E LD_PRELOAD="./success.so" ./bin/boa ``` #### 3.成功模擬  固件見附件文件。
