How did we prevent the online casino token theft incident?
Case of online casino threat response through LIAPP
Recently, as the online casino industry has grown rapidly, countless users around the world are enjoying games conveniently on their smartphones. However, behind the convenience, there are always security threats directly related to money. In particular, tokens or points that can be converted into cash within the game are the main targets of hackers.
Today, we will introduce a token theft incident that actually occurred in an online casino app and share the specific response process of how we strengthened security by applying the ‘mobile security service LIAPP’.
Incident Overview: Token theft and blackmail
A serious security incident occurred in a famous online casino app. Hackers used the app’s vulnerable security structure to analyze and manipulate the internal logic, thereby unauthorizedly generating millions of game tokens. These tokens were assets that could be converted into cash within the platform, resulting in damages worth tens of millions of won. After the incident, the hacker sent a threatening message to the operator based on this, which caused the company to suffer a triple whammy of service interruption, legal action, and loss of user trust for a while.
Cause of security deficiency
At the time, the app had the following security vulnerabilities:
• Game logic exposed within the client (easily analyzed when decompiled)
• Token processing logic exposed in memory, real-time value manipulation possible
• Lack of detection function for forgery/repackaging of the app
• App can be run on rooted devices, hacking tool detection insufficient
These weaknesses provided the perfect attack environment for hackers, and were actually exploited by manipulating memory values to create an unlimited number of tokens.
Response through application of LIAPP
After the incident, the company quickly took security measures and introduced LIAPP, a specialized mobile app security service. LIAPP performs various security functions in real time on the client side to prevent asset attacks such as token theft.
Application of key security features
1) Forgery prevention and integrity verification
• Blocks execution if the app has been tampered with or repackaged
• Checks the integrity of the app code to detect externally inserted code
• Neutralizes attack attempts such as signature forgery or malicious module injection
2) Real-time memory protection
• Protection for values that can be manipulated in real time, such as game tokens
• Detection and termination of memory hacking tools (GameGuardian, CheatEngine, etc.)
• Blocks hackers' attempts to modify memory with real-time protection for internal variables
3) Rooting and hacking tool detection
• Restricts app execution after detecting rooted devices, debugging tools, and reversing tools
• Neutralizes attacks by automatically terminating the app in an environment where hacking tools are running
4) Client logic obfuscation and code encryption
• Protects core game logic from analysis
• Blocks reverse engineering by preventing decompilation
Effects after applying security
After applying security, the casino app experienced the following noticeable changes:
• 100% blocking of token manipulation attempts
• Obtaining hacking tool detection logs → Strengthening response
• Real-time blocking of app analysis/modification attempts → Unauthorized users Block
• Restoring users' trust and normalizing usage
• Securing a favorable foundation for responding to overseas operating regulations and security audits
Above all, it is significant in that the awareness that "asset that can be converted into cash must be protected" has become clear and practical security measures have been prepared to realize this.
Online casino apps are not just games, but digital financial platforms where real assets are traded. Therefore, security is not an 'optional' but a survival condition for business continuation.
A single security incident like this case can destroy trust built up over the years. However, if you apply the right security strategy and solution, you can regain trust and be reborn as a stronger service.
LIAPP is a security service that is absolutely necessary in app environments where assets are traded, such as online casinos, games, and fintech.
Hackers may be targeting your app at this very moment. Take preventive measures, start now.
