Compared to complex MOBA and shooter games, card games possess inherent advantages on mobile platforms, allowing players to enjoy rich content and a satisfying experience centered around collectible cards.
While securing a foothold in the fiercely competitive market, card games also face a wide range of security challenges. JikGuard has compiled several cases of cheating software, analyzed their mechanisms, and proposed solutions.
● SpeedHack
Card games often incorporate progression tasks to sustain long-term operations. The proliferation of speedhack drastically shortens the game's progression cycle, undermines fairness, and leads to dissatisfaction among legitimate players.
Common speedhack work by modifying the system time they obtain to accelerate or decelerate the in-game time flow, such as:
// gettimeofday;
// clock_gettime;
In addition to the common method of manipulating the system time, some speedhack can achieve time manipulation by interacting with the game engine's internal time system. For example, by calling UnityEngine_Time_set_timeScale and passing in the desired acceleration factor, a global speed boost effect can be implemented.
● Cracked Version
Hackers can use tools to remove the game package signature, then employ decompilation methods to tamper with in-game logic, remove or implant certain modules, and finally repackage the content to create pirated versions, cracked versions with in-app purchases, and other unauthorized modifications.
Cracked versions often come bundled with a range of unauthorized add-ons, which undermine legitimate games. If left unchecked, this practice will significantly shorten the game's lifespan.
● Resource Leakage
Among card games, there are numerous content-driven titles that capitalize on distinctive art styles and high-quality narrative experiences to attract players. These games monetize by encouraging players to perform gacha, often leaving them vulnerable to resource leakage issues.
If future updates are prematurely released, it will significantly diminish the element of surprise during gacha draws, potentially disrupting the game's operational rhythm and triggering serious issues such as conflicts within the gaming community.
Additionally, images, videos, or scripts within game resources constitute intellectual property. If Hacked by hackers or competitors who extract their contents, the game faces the risk of plagiarism by rival products, with potentially incalculable consequences.
To address risks such as speed-altering hacks, hacked versions, and source code leaks in card games, JikGuard has developed specialized countermeasures. This solution has been integrated into multiple popular games and has demonstrated outstanding protection capabilities.
SpeedHack Detection and Immediate Exit Feature
Utilizing more fundamental detection methods and validated through extensive real-device testing, this feature detects any SpeedHack or its variants. Upon detecting SpeedHack activity, the game will immediately exit.
Anti-Cheat Feature
To address the risks of game modifications posed by cheats, JikGuard has developed a behavioral detection solution. Paired with an intelligent sensing system featuring over 300 dimensions, it effectively neutralizes all types of cheats and their variants, delivering robust protection.
Anti-Hack Feature
Utilizing JikGuard's industry-exclusive “API Signature Verification-Free Technology,” this solution encrypts game engines and code at the foundational level. It performs multi-layered verification on game package signatures and file integrity to prevent the injection of malicious modules, ad removal, and other unauthorized modifications.
Game Resource Encryption
JikGuard's exclusive resource encryption solution delves deep into the game engine's core architecture. Meticulously engineered to align with game resource file structures and loading mechanisms, it delivers robust encryption protection with minimal runtime overhead and no performance impact. Supported platforms include Android, iOS, PC, and H5.
