Why Is Account Theft So Common in Educational Apps?
A Real-World Solution Based on the LIKEY and LIAPP Implementation Case
“One Account Used by 30 People?”
A security manager at an online education company, Company B, was reviewing login logs when something immediately caught their attention.
A single account was:
- Logging in simultaneously
- From different regions such as Seoul, Busan, and Daejeon
- During the same time period
At first, the team suspected a server error or a reporting issue.
However, after a detailed log analysis, the cause became clear:
Account sharing and account theft were occurring at the same time.
Why Are Educational Apps Such Common Targets?
Educational apps are often easier targets than many organizations realize. The reason lies in the structural characteristics of educational services.
Why Attackers Target Educational Apps
- ✔ Students typically have low security awareness
- ✔ Password reuse rates are very high
- ✔ Automatic login is commonly enabled by default
- ✔ Secure mobile keypads are often not implemented
When combined with the following attack methods, the risk increases significantly:
- Keylogger applications
- Malicious keyboard apps
- Automated input macros
Under these conditions, stealing user IDs and passwords becomes technically straightforward.
The Limitations of Traditional Login Security
"But we already use SMS verification."
Company B believed it had implemented adequate security measures:
- ✔ SMS authentication
- ✔ Enhanced server-side authentication controls
- ✔ Warning logs for suspicious login attempts
Yet these measures failed to prevent actual incidents.
Why?
SMS Authentication
- Can be bypassed through screen capture malware or SMS interception applications
Standard Mobile Keyboards
- User input may be exposed to malicious software
Server-Side Security Alone
- Protects the server but leaves the device largely unprotected
In other words, the company secured the server but failed to secure the user's smartphone.
The Real Problem: Input Protection and Runtime Environment Security
The investigation revealed that most compromised accounts were initially breached on user devices.
Common attack paths included:
- Passwords captured by keyloggers during entry
- Auto-login tokens extracted using hooking tools
- Authentication data stolen from tampered applications
At this point, Company B changed its security strategy.
"Instead of inspecting login results, we need to protect the login process itself."
The Solution: Deploying LIKEY and LIAPP Together
Company B implemented protection for both user input and the application runtime environment.
LIKEY: Protecting Sensitive User Input
LIKEY is a mobile secure keypad solution designed to protect sensitive information during entry.
Benefits of LIKEY
- ✔ Neutralizes keylogger attacks
- ✔ Integrates with cloud-based LIKEY SaaS services
Most importantly:
Passwords are never stored or exposed as plain text on the device.
Even if a malicious application is installed, the entered credentials cannot be captured directly.
LIAPP: Securing the Entire Runtime Environment
If LIKEY protects user input, LIAPP protects the environment in which the application operates.
Key LIAPP Capabilities
- ✔ Detection of malicious apps and hooking tools
- ✔ Prevention of automated login macros
- ✔ Blocking execution of tampered or repackaged apps
- ✔ Detection of rooted devices and emulators
- ✔ Automated input and macro detection through behavioral analysis
As a result, modified applications designed for account sharing could no longer operate.
What Changed After Deployment?
Following implementation, Company B observed measurable improvements.
Security Outcomes
- ✔ Automatic filtering of account-sharing users
- ✔ More than 80% reduction in fraudulent login attempts
- ✔ Near elimination of abnormal simultaneous login patterns
- ✔ Significant decrease in account-related customer support inquiries
The operations team noticed the biggest difference:
“The time spent dealing with login-related issues has almost disappeared.”
In Educational Services, Login Is More Than Access Control
For educational platforms, login is not simply about granting access.
When login security fails, the integrity of critical educational data is compromised:
- ✔ Learning progress records
- ✔ Attendance information
- ✔ Examination results
- ✔ Academic performance records
Once a single account is shared among multiple users, fair assessment and reliable platform operation become impossible.
Educational App Security Is No Longer Optional
Content protection, account protection, and educational fairness are all interconnected challenges.
Addressing them requires more than a single security feature—it requires a comprehensive security framework.
The Three Pillars of Educational App Security
LIAPP
→ App integrity protection and anti-tampering/repackaging
LISS
→ Screen capture, screen recording, and remote assistance detection
LIKEY
→ Sensitive input protection and authentication security enhancement
Together, these solutions form a unified defense strategy for protecting educational services.
It only takes a few seconds for an account to be compromised.
But rebuilding trust can take years.
If you operate an educational platform, now is the time to evaluate your login security strategy.
