Auto click is a technique that mimics user clicks through scripts, system commands, or programming code to enable automated operations. Initially widely used in automated testing and accessibility scenarios, this technology has been exploited by Game Black/Gray Industry as it evolved. It has since infiltrated gaming, social media, live streaming, and other platforms, causing significant disruptions.

DMA (Direct Memory Access) is a technology originally developed for computer design. Its original intent was noble: to allow hardware devices such as hard drives, network cards, and graphics cards to exchange data directly with memory without frequent CPU intervention, thereby significantly improving the computer’s operational efficiency. However, this technology has been maliciously exploited by the Game Black/Gray Industry, leading to the emergence of today’s DMA Cheats.

In the Unity engine, SO (Shared Object) files serve as the core carrier of native code, hosting critical modules such as core gameplay logic, encryption algorithms, and payment verification. This means that once an attacker successfully reverse-engineers an SO file, tasks like memory modification, protocol cracking, and cheat development become significantly easier.

An emulator is software that simulates an Android mobile operating system on a PC. It addresses the pain point of insufficient storage space on mobile devices and prevents the awkward overheating of phones during extended gaming sessions. For certain game genres, using keyboard and mouse controls also enhances the player's gaming experience.

The so-called “magisk cheat” refers to a cheat tool that gains root privileges through the Magisk tool and conceals evidence of cheating. Mask is a commonly available root tool on the market, primarily designed to provide a root environment for devices while hiding both the root status and its own presence.

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.
