Mobile applications must not allow execution on rooted (Android) or jailbroken (iOS) devices to prevent attackers from gaining unauthorized access or modifying app behavior.

Checks available with Bugsmirror MASST:
Bugsmirror MASST performs advanced root and jailbreak detection to identify compromised devices. It immediately blocks access to the app in such cases, ensuring app execution only on secure and unaltered devices.

2. Disallow Developer Mode (Debugging Option) Enabled Devices
NPCI Guideline:
Mobile applications should disallow execution on devices with developer mode or USB debugging enabled to prevent reverse engineering and code inspection.

Checks available with Bugsmirror MASST:
MASST continuously monitors developer options and debugging status. If debugging is found enabled, it restricts app access and notifies the user, protecting sensitive logic from exposure.

3. Ensure App Integrity Checks and Trust Validation
NPCI Guideline:
Applications must implement integrity checks and trust validation by including anti-reverse engineering and anti-debugging mechanisms. They should perform runtime checks with nonce validation, and these checks must be updated with every release.

Checks available with Bugsmirror MASST:
MASST offers anti-reverse engineering and anti-debugging controls that protect the app code and runtime environment. It also validates app authenticity in real-time using dynamic nonce validation, ensuring that every new version maintains integrity against tampering and injection.

4. Ensure OS Integrity Checks
NPCI Guideline:
Applications must verify operating system integrity using mechanisms like Google’s Play Integrity API or similar checks to ensure the device environment hasn’t been compromised.

Checks available with Bugsmirror MASST:
MASST integrates OS integrity verification through custom methods equivalent to Play Integrity. It ensures that even older Android versions (10, 11, 12) or devices not passing CTS or app attestation are still validated through alternate integrity checks, maintaining high trust standards.

5. Not Allowing Android Emulators
NPCI Guideline:
Mobile applications must not run on Android emulators to prevent unauthorized testing, data theft, or automated fraud.

Checks available with Bugsmirror MASST:
Bugsmirror MASST includes emulator detection capabilities that immediately identify and block emulator environments, ensuring that only real physical devices can run the application.

6. Comprehensive Security Testing Before Release
NPCI Guideline:
Every new version of a mobile application must undergo comprehensive security testing before release to identify and fix vulnerabilities.

Checks available with Bugsmirror MASST:
Bugsmirror MASST suite includes static, dynamic, API, and Red Team testing tools that find all kinds of vulnerabilities in a mobile application.

7. Enable APK Locking to Prevent Unauthorized Redistribution and Tampering
NPCI Guideline:
Applications must have APK locking mechanisms to prevent unauthorized redistribution or tampering of app packages.

Checks available with Bugsmirror MASST:
MASST implements a secure APK locking mechanism that validates the integrity of the app package. Any attempt to modify, repackage, or redistribute the app triggers a security response, blocking tampered versions.

8. Implement SSL Pinning to Prevent Man-in-the-Middle (MITM) Attacks
NPCI Guideline:
Applications must implement SSL pinning to prevent attackers from intercepting data through MITM attacks.

Checks available with Bugsmirror MASST:
While MASST supports SSL pinning, it also includes multiple layered transport security checks that validate certificates, block proxy manipulations, and prevent traffic interception, ensuring encrypted and trusted communication between the app and servers.

9. Disallow Any Application Overlay Over the UPI Application
NPCI Guideline:
Applications must not allow any screen overlay or third-party app activity on top of the UPI interface to prevent fraud through tapjacking or spoofing.

Checks available with Bugsmirror MASST:
MASST detects screen overlays, spoofing, and tapjacking attempts in real time. It blocks malicious overlays and prevents background apps from capturing sensitive inputs, ensuring safe user interactions during payments. It also has checks for prevention of screen capturing, screen mirroring, etc.

10. Application Code and Data Integrity Protection at Runtime
NPCI Guideline:
Mobile applications must ensure continuous protection of code and data integrity during runtime. This prevents unauthorized tampering, code modification, or injection of malicious components while the app is active.

Checks Available with Bugsmirror MASST:
Bugsmirror MASST provides real-time runtime integrity protection, continuously monitoring the application for any unauthorized modification or manipulation attempts. It validates core components, APIs, and libraries to ensure that the application remains in its original, untampered state throughout its lifecycle.

11. Debugging Prevention to Block Exploitation Attempts
NPCI Guideline:
Applications must be designed to prevent debugging, as attackers often use debugging tools to uncover sensitive code, identify vulnerabilities, or alter app behavior.

Checks Available with Bugsmirror MASST:
MASST implements anti-debugging controls that actively detect and block debugging attempts. It monitors system calls and debugging hooks in real time, ensuring that even advanced tools cannot attach to the process. Once detected, MASST immediately blocks the session or terminates the app, keeping the business logic and user data fully protected.

12. Root Detection and Root Cloaking Detection
NPCI Guideline:
Mobile applications should identify devices that are rooted or those using root cloaking tools designed to hide compromised environments. Such devices must be restricted from accessing the app.
