Due to the complex runtime environment on PC, cheaters can obtain higher privileges to engage in cheating, making security issues for PC games more severe compared to mobile games. PC game cheating often employs a combination of static analysis and dynamic debugging to identify code logic and its vulnerabilities, thereby further developing cheats and cracks.
In this article, we will focus on analyzing the principles of the x64dbg dynamic debugger and detection solutions.
x64dbg is a powerful dynamic disassembly debugger that can run on various versions of Windows. With its powerful disassembly engine, it can perform analysis and debugging without source code, and is often exploited by black and gray industries to crack games and create cheats.
Compared to traditional Ollydbg, the x64dbg debugger supports both 32-bit and 64-bit program debugging; adopts a visual interface, lowering the technical barrier for cheat development; and also features advanced functions such as memory mapping, data tracking, disassembly, and code graphing.
As an open-source project, x64dbg also has a comprehensive plugin ecosystem, such as the official open-source anti-anti-debugging plugin: ScyllaHide, which can prevent the process from detecting the presence of debugging tools through operations like hooking system API functions.
Additionally, there are various plugins such as Scylla (unpacking and IAT repair), Ret-Sync (IDA synchronized debugging). With the development of numerous black and gray industries, x64dbg's functionality has become increasingly powerful.
Due to the complex cheating situation in PC games, solving game security issues is a comprehensive test of game hardening product capabilities. JikGuard addresses PC game security issues by providing mature and comprehensive customized solutions. This protection solution has been integrated into multiple popular games and has demonstrated excellent protection capabilities.
Anti-debugging Function
Prevents cheat developers from debugging games, blocks static or dynamic analysis of games, and immediately exits when debugging analysis tools such as Ollydbg/x64dbg are detected.
Anti-tampering Function
JikGuard adopts a fully self-developed virtualization packing technology to deeply encrypt game engines, code, and resources, protecting game code and preventing tampering.
Anti-cheat Function
Covers full-scenario anti-cheat solutions for PC games, including intercepting injection, anti-memory modification, anti-speed change, and other functions, effectively blocking various cheats and their variants.
Anti-virtual Environment
JikGuard's exclusive solution can accurately identify various virtual environments, and can immediately exit or report for processing once a virtual environment is detected.
