A library for hiding and retrieving imports in ELF binaries.

• Hide and retrieve symbols in ELF binaries
• Support for multiple architectures (x86, x86_64, ARM, ARM64)
• Cache resolved symbols for performance
• Thread-safe symbol resolution
• Detailed logging for debugging purposes
• Check hooking before calling (ARM and ARM64 only)
• Prevent hooking completely

Compatible Compilers

• GCC or Clang
• Make
• CMake

Clone the repository:

git clone https://github.com/reveny/Android-Native-Import-Hide.git
cd Android-Native-Import-Hide

To include the library in your project, add the following line to your source code:

#include "HideImport.hpp"

Here is a simple example demonstrating how to use the library and make sure to include HideImport.cpp in the source file list:

#include <stdio.h>
#include "HideImport.hpp"

int main() {
    HI_FUNCTION_POINTER(my_malloc, void*, size_t size) = HI_GET("libc.so", "malloc");

    void *testMemory = my_malloc(20);
    printf("my_malloc test returned: %p\n", testMemory);
    free(testMemory);

    return 0;
}

#include <stdio.h>
#include "HideImport.hpp"

int main() {
    void *testMemory2 = HI_CALL("libc.so", malloc, void*, size_t)(15);
    printf("malloc test 2 returned: %p\n", testMemory2);
    free(testMemory2);

    return 0;
}

#include <stdio.h>
#include "HideImport.hpp"

int main() {
    void *testMemory2 = HI_CALL_SAFE("libc.so", malloc, void*, size_t)(15);
    printf("malloc test 2 returned: %p\n", testMemory2);
    free(testMemory2);

    return 0;
}

The SAFE version will check if the function is hooked before calling. If the function happens to be hooked, the call will not be executed and return NULL.

A single header version of the library is available for convenience. Simply include single_header/HideImport.hpp in your project.
