JikGuard-Mac Hardening Tool Version 1.0.2 Release Notes:
■ Support for AssetBundle resource encryption;
■ Support for Unity global-metadata file encryption;
An AssetBundle is a compressed resource package provided by Unity. It stores game resources such as images, models, textures, audio and video files, and code.
The images, models, videos, and other files contained in AssetBundle files are critical game resources. If they are hacked by hackers or competitors and their contents are extracted, this could lead to serious issues such as product plagiarism and intellectual property infringement.
There was an incident involving the plagiarism of art assets in *Halo 4*
The `global-metadata.dat` file contains information such as class names, property names, and strings from the C# code; the engine relies on this data to implement certain C# language features.
When il2cpp launches, it reads the required class names, property names, and other information from this file; it is precisely this mechanism that makes it easy to create Cheats and Hack the game. Therefore, it is essential to apply strong encryption to the global-metadata.dat file.
Introduction to the Mac Hardening Solution
The JikGuard Game Hardening and Anti-Cheat Solution is a comprehensive anti-cheat solution for the macOS platform that combines security hardening with an anti-cheat SDK and real-time online signature updates. This solution runs on macOS and is designed to harden Unity and Xcode projects.
Key Features
● Anti-debugging Protection
Dual-layer protection: First, detection methods such as ptrace, syscall, sysctl, and exceptions are employed; then, the protective code is encrypted for enhanced security.
● Anti-Re-signing Protection
Accurately verifies the signature within the package by comparing the signature stored during the hardening process with the signature obtained at runtime.
● Anti-Modification Protection
During the code protection phase, JikGuard provides local code detection and ensures its integrity.
In addition, JikGuard has developed an online signature update detection feature that allows signatures to be distributed immediately upon receiving a sample, ensuring the app’s security in the shortest possible time.
