Preventing Location Information Falsification – A Case Study of Using LIAPP for Mobile App Security
Hello. Today, I'd like to share a case study of protecting apps from hackers who manipulate location information (GPS) in mobility-based services to gain illegal benefits.
In particular, I'll share a real-world experience of successfully detecting and blocking GPS spoofing apps through the application of the mobile security service LIAPP.
Problem: Location-based services misused through GPS manipulation
Mobility services often have different fares depending on the user's location or offer benefits that are only available in certain areas.
However, the following malicious attempts have recently been discovered:
• Using GPS manipulation apps to disguise movement to a false location
• Unauthorized participation in fake location-based rewards and events without actual movement
• Falsifying driving and commuting records to receive unauthorized allowances and fares
Hackers exploited these services by manipulating and transmitting the device's location information using separate GPS fake apps or virtualization tools with location alteration capabilities. This damage resulted in disadvantages for honest users and a decline in service reliability.
Countermeasures: Detecting and Blocking Location Falsification with LIAPP
To counter these location manipulation threats, we introduced the mobile security service LIAPP, establishing a system for detecting GPS falsification and blocking it based on environmental analysis.
Key Security Features of LIAPP Application
1. Location Information Forgery Detection
• Real-time analysis of abnormal fluctuation patterns in device GPS information
• Detection of Mock Location usage
• Detection and blocking of apps or frameworks that induce location falsification
2. Virtual Environment and Rooting Detection
• Detection of rooted devices and virtual devices commonly used for GPS manipulation
• Blocking execution in emulator environments
• Blocking plugins that bypass rooting and location manipulation
3. App Execution Integrity Verification
• Detection of GPS-related code forgery and modification attempts
• Detection of app repackaging and blocking execution
Application Results
After implementing LIAPP, the service operations team experienced the following tangible benefits:
• Blocking over 89% of location manipulation attempts
• Improved detection rate for mock location and GPS spoofing apps
• Maintaining zero instances of false driving records and reward abuse
• Restoring user trust and improving app ratings
Most importantly, the system maintained the user experience for legitimate users while precisely detecting only malicious manipulation.
In conclusion
Location-based services are a key feature that provide convenience and a user-centric experience, but they also carry the constant risk of forgery and manipulation.
With LIAPP, we've implemented a security system that goes beyond simply checking GPS information to comprehensively analyze the execution environment, app integrity, and user behavior logs, enabling us to provide a more stable and reliable service.
If you operate an app service where location information is crucial, we strongly recommend considering preemptive security measures through LIAPP.
