In-App Purchase Protection Case Study to Prevent Automatic Payment Bypass – Introduction of LIAPP
Hello!
Today, we'll introduce a case study of strengthening payment security in a mobile game app. Specifically, we'll explain how LIAPP effectively prevented hackers from bypassing in-app purchases (IAPs) to obtain paid items without authorization.
Payment bypassing in game apps is a real thing.
When operating a mobile game, you may occasionally discover unusual payment histories. Some of these attacks occur through the following:
- Manipulating the in-app purchase (IAP) screen to obtain items without payment.
- Falsifying payment response values to deceive the server.
- Rooting the device and manipulating the app's internal payment logic.
- Integrity threats using illegal marketplaces or hacking tools.
If left unchecked, these attacks can lead to not only revenue loss but also the loss of legitimate paying users. These threats are especially critical for RPGs, strategy games, and collectible games, where item value is high.
Background for the Introduction of LIAPP: The Need for In-App Purchase (IAP) Protection
After recognizing automated payment bypasses and integrity attacks using hacking tools, our team introduced 'LIAPP,' a specialized mobile security service, to strengthen app security.
LIAPP is a security service optimized for protecting in-app payments, providing features that go beyond simple code protection to include integrity verification of the actual payment flow and server-linked security.
Security Features Applied
1. Payment logic protection and tamper prevention
- Encryption and obfuscation of in-app payment-related code
- Detects rooting, hooking, and debugging attempts to halt payments
- Repackaged apps are blocked from running → Illegal APKs are blocked
2. Implements server-linked payment verification logic
- After payment is completed, communicates with the server to re-verify the actual payment
- Compares Google/Apple server responses with our own logic
3. Security event logs and monitoring
- Identifies and blocks users exhibiting abnormal behavior
Changes since implementation
Since implementing LIAPP, we have experienced the following results:
- Abnormal payment rate reduced by approximately 96%
- Increased access blocking rate for users using illegal APKs
- Attempts to acquire in-game paid items without authorization Block
- We've received numerous positive user feedback, including "high payment security."
- We've also passed the app security certification process in both store and platform reviews.
The best part is that we were able to enhance security without compromising the normal user experience.
In conclusion
As the mobile gaming industry grows, payment security has become a key element directly related to game profitability.
LIAPP not only protects the payment process, but also comprehensively addresses the integrity of the entire app, rooting/hacking prevention, and server integration verification, making the mobile payment environment much safer.
If you're running a game app, we recommend strengthening your payment security with LIAPP right now. Protecting paid content is essential to preserving the value of your game.
