No more unauthorized leaks of game premium content!

LIAPP — Wed, 01 Oct 2025 03:49:47 +0000

No more unauthorized leaks of game premium content!
Introducing a case of blocking screen capture and recording with LISS
When playing a game, premium content such as paid stories, limited illustrations, and strategy information that can only be viewed after payment often appears. From the developer's perspective, such high-quality content is a key element that creates the game's revenue model and brand value.

These days, premium content provided through mobile apps is becoming more diverse and sophisticated. In particular, in game apps, there are many contents that are used as elements to induce users to pay, such as paid stories, high-quality illustrations, and high-quality strategy information. However, cases of unauthorized leaks of such content through screen capture or screen recording are constantly occurring, and developers are increasingly concerned about security.

Today, we will introduce an actual application case of 'mobile app security service LISS' that solved these concerns. This is a case where illegal leaks of premium content were effectively blocked through LISS's screen capture and screen recording blocking functions.

Unauthorized capture and video leak of paid content
The method of leaking paid content is simpler than you think.
All you have to do is save the game screen with the smartphone's basic capture function or record the screen using an external app, and share it on SNS, communities, video platforms, etc.

The problem starts here.
• Paid story leak: Content can be viewed without paying → Damage to revenue structure
• Illustration leak: Loss of rarity → Reduced incentive for users to pay
• Strategic information leak: Collapse of competition structure → Damage to game balance
• Risk of design theft: Copyright infringement by a third party using captured images or videos

In other words, a simple screenshot or video can destroy the game ecosystem.

LISS's screen capture/recording prevention function
'LISS' is a powerful app security service developed by Lockin Company, a mobile application security specialist. It blocks security threats to various apps including games in real time and provides various functions to prevent unauthorized content leaks.

Among them, the following two features are particularly noteworthy:
1) Screen capture blocking
• Disable basic capture functions (Fn+Power, 3-finger capture, etc.)
• Block external capture apps (e.g. Screenshot Easy, AZ Screen Recorder, etc.)
• Automatically black screen when sensitive content is exposed

2) Screen recording prevention
• Automatically terminate or blackout the app when screen recording is detected
• Detect Google Play game recording, Discord overlay, and streaming tools
• Provide warning messages when users and hackers attempt to record screens

These features are more practical in that they can be set in detail to apply only to sensitive content areas within the game client.

Real-world application case: Introduction of LISS to protect paid content
A famous domestic RPG game developer recently experienced an incident where the paid story and advanced illustrations of its game were leaked in large quantities through a video platform. Some users were consuming the content thinking, “I can just watch the video without paying,” which directly led to a decrease in sales.

Accordingly, the developer introduced LISS and took the following measures:
• Screen capture/recording prevention settings for the story playback section and illustration viewer functions
• Automatic forced termination function applied when screen recorder is detected

As a result, the number of leaks decreased sharply, and the community also experienced real security effects with responses such as "Capture is not working" and "Video recording is blocked?"

Isn't it inconvenient for users?
Some users responded by saying, "Why can't I capture the screen?" and "I tried to share it, but it doesn't work." However, this inconvenience is within the acceptable range as it is a device to protect the value of game content and provide the same experience to all users.

About a month after applying the security feature:
• The number of leaked images and videos uploaded in major communities decreased by more than 90%
• Improved awareness through user feedback: "Content protection feels more thorough", "I trust the game"
• Internally, we gained confidence based on security in content marketing strategies and paid product composition

As a result, applying the security feature was more than just 'blocking'. It has become an important means of protecting the value of premium content and increasing brand reliability.
Above all, since the capture/recording blocking function is applied only to paid content sections, it has little effect on general play.

Rather, it provides a sense of trust and satisfaction that "only those who have paid properly can enjoy the content."

Paid content in games is not just graphics or videos. It is the fruit of the efforts and creations of numerous developers, and a promise to users. Protecting such content from unauthorized leaks becomes more complete when technical protection measures are combined with legal protection.

The value of mobile content can be properly protected when security is supported. In particular, app services that aim to monetize premium content require even more thorough preparation.

Why LISS?
LISS is chosen by many companies for the following reasons:
• Provides features specialized for mobile content security, such as screen capture/recording prevention
• Real-time monitoring with a cloud-based dashboard
• Cross-platform compatibility supporting both Android and iOS

LISS's screen capture and recording blocking features are not simply technical features, but strategic choices that protect the value of premium content. At the same time, it is a realistic solution that helps mobile game companies strengthen content security and protect their brand value.

Check out LISS right now, the security that protects the value of creation.

Strengthening User Authentication of Electronic Civil Service Apps Mobile App Security LIAPP Application Case

LIAPP — Wed, 17 Sep 2025 05:07:32 +0000

Electronic Civil Service Apps, Security is Life – User Authentication Made Stronger with LIAPP
Have you ever used electronic civil service services? Various public agency apps such as Government24, Citizens’ Archive, and Civil Service24 have now become essential services in the daily lives of citizens. However, since they handle sensitive personal information and administrative information, strong security is vital. Recently, the number of public institutions applying ‘mobile security service LIAPP’ to strengthen user authentication of these electronic civil service apps is increasing. In particular, the role of LIAPP, which protects the login process through the security keypad, is attracting attention.

Today, we will take a closer look at the application cases and how LIAPP protects our information.

Why is electronic civil service app security important?
Electronic civil service apps go beyond simple information search and provide important administrative services such as issuing resident registration copies, paying taxes, and filing civil service applications. In this process, they have a structure that is easily exposed to security threats such as personal information leaks and authentication forgery.

In particular, the following threats exist due to the nature of smartphone-based app services.
• Access from rooted/jailbroken devices
• Memory hacking through malicious apps
• Information theft through screen capture
• Input value theft from the security keypad

To respond to these threats, mobile app security is what is needed.

What is LIAPP?
LIAPP is a global mobile security service developed by Lockin Company, a mobile application security specialist. LIAPP is designed to detect security threats in real time when the app is running, protect the app from malicious behavior, and safely process authentication information.
The main security features are as follows:
• Prevention of app forgery and modification
• Detection of rooting/jailbreak
• Prevention of memory hacking
• Protection of security keypad
• Screen capture blocking
• Detection and prevention of debugging
• Application of real-time security policies

Cases of LIAPP applied to public institutions
LIAPP has recently been introduced to electronic civil service apps operated by several central government agencies and local governments. They are especially focusing on LIAPP in the user login screen and the security keypad input section, safely protecting the core section of user authentication.

Strengthening the login security of the civil complaint app
A public institution was operating a structure in which a user ID and password were entered using a security keypad when logging into the civil complaint app. However, there was a problem that this input process was vulnerable to screen capture or key input hacking.

Therefore, by applying the security trio LIAPP, LIKEY, and LISS of Lockin Company, the following security effects were achieved:

• Screen capture and screen mirroring blocking
• Debugging and reverse engineering detection blocking
• App execution blocking on rooted devices

As a result, the possibility of civil complaint information leakage was significantly reduced, and service reliability was significantly increased.

Changes in security felt from the user's perspective
Apps with LIAPP, LIKEY, and LISS applied provide a noticeable sense of stability from the user's perspective. Although the security keypad operates slightly differently from the general keypad and screen capture is blocked, which may cause some inconvenience, these are essential protection devices to protect the user's personal information. Above all, users can use the app with confidence, and public institutions are also seeing the effect of greatly reducing the risk of security accidents.

How safe is the civil service app you use?
In the digital age, civil service services can be easily used with smartphones. However, behind convenience, thorough security must be supported.
The mobile security service ‘LIAPP’ is a strong guard that ensures that electronic civil service apps can be used with confidence. We hope that more public institutions will adopt this security technology in the future so that all citizens can experience trustworthy digital administrative services. It is also an important attitude as a digital citizen to pay attention to whether public service apps have enhanced security.

Preventing Mobile Game Cheating by Blocking Rooted Devices Application Case of Mobile App Security LIAPP

LIAPP — Tue, 02 Sep 2025 02:51:01 +0000

A Choice for Fair Gaming
Anyone who has experience developing or operating a mobile game has probably been concerned about the issue of ‘cheating’ at least once. Cheating that breaks the game balance, gives unfair advantages to other users, and ultimately destroys the trust of the entire game community.

The most representative method among them is system hacking using rooted devices.

Today, we will introduce a real case where we introduced ‘mobile security service LIAPP’ to solve this problem and applied rooting detection and execution restriction functions to effectively block cheating.

What is a rooted device? Why is it dangerous?
Rooting generally refers to an act in which a user (or hacker) directly acquires system privileges of the Android operating system (OS) that are restricted by the manufacturer or carrier. Rooting causes the following risks:
• Modification of system files and security policy bypass
• Free execution of cheating tools or memory hacking apps
• Manipulation of internal data of game apps or encryption bypass
• Bypassing in-app purchases, creating unlimited resources using hacking tools, etc.

In other words, it is no exaggeration to say that any security device can be breached on a rooted device.

Real-life case: Spread of cheating in a rooted environment
As a result of tracking the logs, commonalities were revealed:
• Execution on a rooted device
• Use of memory manipulation tools
• Forgery of internal scripts and asset data

Ultimately, they were cheating by manipulating game resources in a rooted environment without permission to achieve rapid growth and high rankings, widening the gap with normal users.

Successful blocking of cheating by introducing LIAPP
The game company in question recognized the seriousness of the situation and quickly introduced LIAPP, a mobile app security solution.
LIAPP provides various security features optimized for mobile games, and is particularly strong in rooting detection and execution restriction functions.

Applied security features
1) Rooting detection and app execution blocking
• Automatically blocks apps when running on rooted devices
• Precisely detects rooting traces such as su binary, BusyBox, and Magisk
• Detects rooting bypass attempts and completely blocks them

2) Detection of cheating tools and hacking apps
• Detects popular cheating tools such as GameGuardian, CheatEngine, and Lucky Patcher
• Immediately terminates the app or displays a warning when a hacking tool is detected while the app is running
• Records cheating attempt history on the server → Used as a basis for user sanctions

3) Added user response logic for abnormal environments
• Provides users with the reason and induces recovery when rooting is detected
• Minimizes backlash with flexible security UX configuration rather than disabling the app

**
Developer interview**
“In the past, one cheater could shake up the entire server. Now, after introducing LIAPP, that risk has almost disappeared, and the operation team can focus on its original role.”

Changes after applying security
About a month after applying security, there were the following positive changes:
• 100% blocking of cheating attempts based on rooted devices
• Increased satisfaction of normal users due to sanctions on hacking users
• Recovery of game ratings, increased reliability on Google Play Store
• Many favorable comments on “securing fairness” in the community and SNS

Above all, the biggest achievement was that it laid the foundation for normal users to stay longer without leaving.

Security is the first step toward fairness
In mobile games, ‘fun’ and ‘competition’ are inseparable elements. However, if the basis of competition is unfair, the game will never last long. In particular, rooting and cheating are very dangerous elements that can lead to not only loss of sales for a company, but also loss of normal users and damage to the brand image.

LIAPP can be applied quickly without complex development, and it is a smart choice that can build a security ecosystem for the game by combining various security features.

Real security is blocking the entire cheating environment, rather than blocking one cheating user. As in the case introduced today, the fairness and user experience of the game can be greatly improved with just the rooting detection and execution restriction functions. If you are a mobile game operator, take your security to the next level right now with ‘LIAPP’.

How did we prevent the online casino token theft incident?

LIAPP — Tue, 26 Aug 2025 01:50:35 +0000

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.

Public bicycle app, is user personal information safe?

LIAPP — Wed, 20 Aug 2025 04:37:17 +0000

Introduction to personal information protection case through LIAPP
These days, public bicycle service is easily available all over the city. Many people use it because anyone can rent a nearby bicycle with a mobile app and move around easily. However, did you know that behind this convenience, there is a security threat of user personal information leakage?

Today, we will introduce a real case where the mobile APP security service LIAPP was introduced to protect personal information of public bicycle apps and storage data encryption and forgery detection security were applied.

Personal information leakage is not someone else's problem
Public bicycle apps collect and process various information in addition to simple rental functions. For example:
• User basic information such as name and phone number
• Payment method information (card registration, simple payment, etc.)
• GPS-based usage location and movement route
• Rental/return history and time zone analysis information

Most of this data is processed through in-app storage or communication with servers, and if security is not properly applied, there is a high risk that it can fall into the hands of hackers. In particular, data stored on the terminal requires thorough protection, as the device can be easily accessed by hijacking or rooted devices.

Security features applied through LIAPP
The public bicycle operator introduced the mobile app security service LIAPP to better protect users' personal information. LIAPP is a security SDK that can be easily integrated into the app, and can detect and automatically respond to various threats when the app is running.

Code obfuscation, encryption
By encrypting all user information stored in the app (e.g. login information, recent rental history, etc.), the following security is achieved:
• Blocking access through rooted devices or decompilation tools
Detection of app forgery and integrity
• Automatically detects and blocks execution when the app is modified or repackaged and malicious code is inserted
• Prevents hacker analysis through hacking tools, debugging tools, and rooting detection
• Blocks personal information theft through unauthorized malicious versions at the source

Effects after application
The operating company achieved the following improvements after applying LIAPP security:
• 100% detection and blocking of information access attempts using hacking tools
• Automatic termination of app execution in rooted devices and abnormal environments
• Increased app ratings and usage rates due to improved user trust
• Easier response to security certification from public institutions

In particular, it is drawing attention as a case that preemptively took technical protection measures in line with the recent strengthening of the Personal Information Protection Act and the strengthening of security audits by administrative agencies.

Personal information protection is now a necessity, not an option
Security threats to mobile apps are becoming increasingly sophisticated. Especially for apps connected to public services or social infrastructure, security is a task that must come first in order to secure social responsibility and trust.
LIAPP is a cloud-based security solution that can be applied quickly without complex development, and is already being used in numerous public institutions, financial institutions, and utility apps.

In conclusion
For services that citizens use on a daily basis, such as public bicycle apps, trust in security is the lifeblood of the service. Isn't providing a safe data environment, beyond providing convenience to users, the key to true digital transformation?

LIAPP will be a strong partner that protects your app from hacking threats and protects user personal information.

Introduction to the application of mobile app security LIAPP for used car price data protection

LIAPP — Tue, 12 Aug 2025 04:49:16 +0000

As the used car market becomes digitalized, app-based used car price comparison services are growing rapidly. While it provides convenience to consumers and new opportunities to businesses, it also increases the risk of price algorithms or internal data being leaked to the outside.

Today, we will introduce a mobile security application case of a used car platform company that effectively responded to these risks. This company safely protects important data by applying code encryption and SSL Pinning through a mobile security service called LIAPP.

Why does used car price data need protection?
The core of a used car app is ‘accurate and reliable price information.’ In order to create this data, complex algorithms and internal databases that reflect transaction history, region, model year, mileage, and market trends are required.

However, if such core information is included in the app without protection, it is exposed to the following threats:
• Reverse engineering of the price algorithm
• Interception of API communication and data collection
• Mass crawling through unauthorized apps or bots
• Unauthorized data collection and imitation of competitors

This can lead to problems such as loss of competitive advantage, collapse of the revenue model, and decrease in trust.

Security application through LIAPP
To respond to these threats, the company introduced a mobile security service called LIAPP. LIAPP is a cloud-based service that provides powerful security features with just a simple SDK application.

Applied security features

Code encryption
• Encrypts code areas containing core logic and algorithms to prevent decompilation and reverse analysis
• Blocks hackers from figuring out the internal structure or replicating the algorithm
SSL Pinning
• Prevents man-in-the-middle attacks (MITM) by fixing certificates in the communication section with the server
• Blocks API eavesdropping and data leakage using proxy tools (Fiddler, Charles, etc.)
Rooting and hacking tool detection
• Restricts app execution when a rooted device or hacking tool is detected, blocking the possibility of data leakage
Repackaging and forgery detection
• Detects in real time whether the app has been tampered with or repackaged, and blocks execution

Changes after applying security
After applying security, the used car platform experienced the following noticeable effects:
• Reduced attempts to expose internal algorithms
• Blocked attempts to call illegal APIs
• Automatically detects and responds to attempts to analyze apps
• Reduced cases of data imitation in competing services
• Increased reliability of the platform

In particular, SSL Pinning was used to collect data from outside With crawling attempts completely neutralized, stable service operation centered on normal users has become possible.

User experience intact, security stronger
Many people worry that introducing a security solution will affect the user experience. However, LIAPP operates in a way that strengthens backend security without affecting the user UX. Security settings are easily maintained even when the app is updated, and the management burden on developers is not large.

We live in an era where digital assets are the competitiveness of a company. In particular, sensitive data such as used car prices are the core value of a business in themselves. No matter how excellent a service is, it is difficult to maintain its value if security is lax.
LIAPP is a service that can further strengthen the security of mobile apps without complex settings, helping you focus on your business without worrying about data leaks.
If you are operating a used car app or need to protect internal algorithms and data, consider introducing LIAPP right now.

Protecting Mobile Game Revenues by Blocking Distribution of Cracked APKs, Introduction to LIAPP Application Cases

LIAPP — Wed, 30 Jul 2025 01:10:47 +0000

The mobile game market continues to grow every year and generates huge revenues worldwide. However, there is a fatal problem that hinders this growth: the illegal distribution of cracked APKs. Many game developers are seriously suffering from in-app payment revenues due to this, and it is even threatening the survival of the game.

Today, we would like to share a successful story of protecting game app revenues by focusing on the case of applying ‘LIAPP, a mobile security service’ to solve this problem.

What is a cracked APK?
A cracked APK refers to an app that was decompiled by a hacker and repackaged or redistributed with security disabled.

Most of these apps are illegally distributed for the following purposes:
• Bypassing in-app payments
• Removing advertisements
• Providing unlimited in-game resources (e.g. gold, diamonds, items, etc.)
• Inserting malicious code

Ultimately, normal users suffer losses and developers lose revenue.

Real losses due to bypassing in-app payments
The most important revenue model for mobile games is ‘in-app payments (IAP)’. Users can purchase desired items while enjoying the game or pay for quick growth. However, users using cracked APKs can enjoy all these benefits without going through the normal payment process.

In fact, a small and medium-sized game company experienced a decrease of more than 30% in total sales in a month after distributing cracked APKs, and faced a situation where normal users even left due to cracked files being indiscriminately shared in the community.

Preventing forgery and repackaging with LIAPP
In this situation, the game company introduced ‘LIAPP,’ a mobile app security service. LIAPP provides real-time forgery detection and repackaging prevention functions, thereby realizing the following security effects.

Key security features applied

APK forgery detection
• Real-time file integrity verification, blocking execution of modified apps
Repackaging prevention
• Identify abnormal packaging by verifying app signature integrity
Debugging prevention and rooting detection
• Preemptively blocking hackers from analyzing or manipulating apps
App analysis tool detection
• Detects and automatically terminates representative hacking tools such as Frida, Xposed, and Lucky Patcher

Effects after applying security
After strengthening security, game companies experienced noticeable performance improvements.
• Blocking illegal users by setting the app to automatically terminate when using cracked APKs
• Sharp decrease in sharing within the community as cracked files that were being distributed became useless
• Increased payment rate and return visit rate of normal users
• Improved reliability by announcing the fact of security enhancement

Above all, it was possible to kill two birds with one stone: sales recovery and user base stabilization.

Game security, join LIAPP!
As much effort was put into game development, it is also very important to safely protect the resulting app. In particular, for mobile games that rely on in-app payments as their main source of revenue, security is not an option but a must.

‘LIAPP’ is a global service that provides powerful security features with simple application without complex development knowledge.

I highly recommend that game developers who are concerned about the distribution of cracked APKs take a look at it.
Let’s protect the game we created together.
