# Code Virtualizer Method Swizzling Demo
|
|
|
|
This project demonstrates [Oreans Code Virtualizer](https://www.oreans.com/CodeVirtualizer.php) protection applied to Objective-C method swizzling on macOS (arm64).
|
|
|
|
## Project Files
|
|
|
|
### Source Files
|
|
|
|
- `swizzle.m` - Dynamic library that performs Objective-C method swizzling
|
|
- Protected with Code Virtualizer macros (`VIRTUALIZER_START`, `VIRTUALIZER_END`, `VIRTUALIZER_STR_ENCRYPT_START`, etc.)
|
|
- Includes Stealth Code Area for additional anti-debugging protection
|
|
|
|
- `test_swizzle.m` - Test program to verify the swizzling functionality
|
|
- Logs the output to demonstrate the effect of the swizzling
|
|
|
|
### Built Artifacts
|
|
|
|
- `libswizzle_arm64.dylib` - Unprotected version of the swizzling library
|
|
- `libswizzle_arm64_protected.dylib` - Protected version (virtualized with Code Virtualizer in Demo mode)
|
|
- `test_swizzle_arm64` - Compiled test executable
|
|
|
|
## Building
|
|
|
|
```bash
|
|
make all
|
|
```
|
|
- `libswizzle_arm64.dylib` : The swizzling dynamic library
|
|
- `test_swizzle_arm64` : The test executable
|
|
|
|
## Running the Demo
|
|
Note: SIP must be disabled to run the demo due to the use of `DYLD_INSERT_LIBRARIES` for method swizzling.
|
|
```bash
|
|
./scripts/demo_swizzle.sh
|
|
```
|
|
|
|
## Code Virtualizer Protection
|
|
|
|
The `swizzle.m` file demonstrates several Code Virtualizer features:
|
|
|
|
### Virtualization Macros
|
|
- `VIRTUALIZER_START` / `VIRTUALIZER_END` - Marks code sections to be virtualized
|
|
- `VIRTUALIZER_STR_ENCRYPT_START` / `VIRTUALIZER_STR_ENCRYPT_END` - Encrypts string literals
|
|
|
|
**Note:** `VIRTUALIZER_STR_ENCRYPT_START` is not available in the demo version.
|
|
|
|
|
|
### Stealth Code Area
|
|
The code includes a stealth area that:
|
|
- Provides additional anti-debugging protection
|
|
- Makes analysis more difficult
|
|
- Uses `STEALTH_AREA_START`, `STEALTH_AREA_CHUNK`, `STEALTH_AREA_END` macros
|
|
