Mobile game hacking, preventing it from even starting! Introducing a case of blocking debugging tools with LIAPP

If you are a mobile game developer, you may have heard of debugging tools such as Frida, Xposed, and Magisk. And you probably know that these tools are the starting point of game hacking.

Attempts to analyze game code, manipulate resources, or create illegal tools (so-called 'hack tools') using these tools are becoming increasingly sophisticated.However, now, these attempts can be blocked before they even start. That is, through the 'mobile app security service LIAPP'.

Today, we will introduce a case of actually applying debugging tool detection such as Frida and Xposed to a mobile game app and preventing the creation of hacking tools in advance.

Where does game hacking start?

Most hack tool productions for mobile games follow the following flow:
 1. Hooking apps using Frida or Xposed Framework
 2. Monitoring and manipulating function calls in real time
 3. Tracking and manipulating game internal variables
 4. Automating with cheat apps or hack tools

In other words, hack tool production is impossible without prior analysis using debugging tools.

So what can you do? If you detect and block debugging tools themselves so that hackers cannot analyze them at all, you can completely block the first gateway to game security.

LIAPP's debugging tool detection function

'LIAPP' is a mobile app security solution introduced by numerous domestic and foreign game companies, and is designed to detect and block various security threats in real time when running apps.
One of its core functions is the debugging tool detection and blocking function.

Representative tools that LIAPP can detect and block:
 • Frida
 • Xposed / LSPosed
 • Magisk and Magisk modules
 • Attempts to link with reverse tools such as Jadx and JD-GUI
 • Activation of ADB debugging session
 • All runtime debugging/hooking tools

Blocking method:
 • Immediately blocking app execution on devices where the tool is installed
 • Automatically terminates when abnormal processes or libraries are detected
 • Memory protection and real-time hooking defense
 • Warning message output or forced termination of app when entering app debugging mode

Practical application case: Preventing hacking in advance by blocking debugging tools

A famous domestic strategy RPG game company detected abnormal behaviors such as automatic battle, infinite goods, and cooldown removal through user analysis from the beginning of its launch, and confirmed that most of them were caused by Frida-based hacking tools.

To solve this, we applied LIAPP's debugging tool blocking function.
Application items:
 • Force-terminate the app immediately when Frida and Xposed are detected
 • Automatically block ADB debugging and rooting status
 • Real-time scan for tool installation when running the app

Results:
 • A sharp decrease in the number of automatic hunting bot users in the game
 • Reactions such as "hacking blocked" and "Xposed does not work" in Google Play reviews
 • Many reports of failed hacking of the game in the illegal tool production community

In other words, it was a successful security application case that prevented even attempts at game hacking.

If security is weak, the game's lifespan is shortened

Mobile games are not just entertainment, but also a digital content business that affects sales, brand, and user community.

However, the moment hackers are allowed to analyze them, the following risks may arise:
 • Ineffectiveness of inducement items → Sales decrease
 • Collapse of fairness between hacking users and general users → Increase in defection
 • Loss of community trust → Damage to the game brand

Therefore, security is not an option, but an essential element that must be prepared before launch.

Just by blocking the debugging tool analysis that is the beginning of game hacking, you can block numerous security threats in advance.
The debugging tool detection function of ‘LIAPP’ blocks hackers from entering the game itself, protecting the game’s fairness, sales stability, and brand image at the same time.

The success or failure of a game depends on security. Protect your game with LIAPP right now.
