Key Findings

Critical Security Issues (2)

1. WebView File Access Vulnerability

   • Third-party content loaded in age verification can access local device files
   • Could expose encrypted settings, database files, and user data
   • Impact: High risk of data theft if malicious content is loaded

2. Centralized Wallet Infrastructure

   • All wallet keys managed exclusively through third-party service (Turnkey)
   • Single point of failure for all user wallets
   • Service compromise or outage could affect wallet access for all users

High Security Issues (6)

3. Unencrypted Local Database

   • Chat messages, contacts, and transaction history stored without encryption
   • Accessible with device root access or malware with elevated privileges

4. Excessive Third-Party Web Access

   • Mini-apps can trigger payments, access contacts, and use microphone
   • Risk of malicious mini-apps performing unauthorized actions

5. Outdated Cryptography Library

   • Uses 3-year-old Web3j library for blockchain transactions
   • May contain known security vulnerabilities

6. Overly Permissive File Sharing

   • App can access entire external storage, not just specific folders
   • Could allow access to user's private documents

7. Face Authentication Bypass Risk

   • Security thresholds for face recognition exposed in app code
   • Attackers could create synthetic images to bypass authentication

8. Unvalidated Camera/File Access

   • Third-party scripts can trigger file picker or camera without validation
   • No origin checks or explicit user confirmation

Privacy Concerns (3)

9. Extensive Tracking Infrastructure

   • 10+ analytics SDKs with overlapping capabilities
   • Includes Braze, PostHog, AppsFlyer, Statsig, Datadog, Fingerprint.js, Firebase, and more

10. Device Fingerprinting

    • Automatic device fingerprinting with no user opt-out
    • Enables persistent tracking that survives app reinstalls

11. Closed-Source Document Scanner

    • Third-party passport scanning SDK with privileged access to sensitive ID data
    • No visible independent security audit

---

Security Strengths

• Strong Network Security: Certificate pinning implemented for main API endpoints
• Hardware-Backed Encryption: Android Keystore integration with hardware security
• Privacy-Preserving Authentication: Zero-knowledge proofs for identity verification
• End-to-End Encryption: Chat and backup data encrypted end-to-end
• Modern Cryptography: Google Tink library for AES-256 encryption
• Cloud Backup Protection: Standard backups disabled to prevent Google Cloud exposure

Compliance & Standards

Areas for Improvement

Data Protection:

• Local database encryption would better protect user data
• Single points of failure in wallet infrastructure increase risk

Privacy Controls:

• Limited opt-out mechanisms for tracking
• Device fingerprinting occurs automatically

Third-Party Risk:

• Multiple analytics SDKs increase attack surface
• Closed-source components handle sensitive data without transparency

---

Who Should Use This App

Best For:

• Tech-savvy users who understand blockchain and crypto wallets
• Users who value zero-knowledge identity verification
• People comfortable with extensive tracking in exchange for free services
• Users seeking proof-of-humanity for online services

Avoid If:

• Privacy-focused users uncomfortable with 10+ tracking SDKs
• Users handling large cryptocurrency assets (due to centralized wallet risks)
• Users requiring offline wallet backup options
• Users on rooted/jailbroken devices (due to unencrypted database)

---

Recommendation: Significant Security Concerns

Verdict: Critical WebView vulnerability allows file access to local data, centralized wallet infrastructure, and excessive tracking SDKs. Only recommended for tech-savvy users understanding the risks; unsuitable for privacy-focused users or those holding significant assets.

Risk Summary:

• Security Risk: Moderate to High (WebView vulnerability, wallet centralization)
• Privacy Risk: Moderate (extensive tracking, device fingerprinting)
• Data Protection: Moderate (unencrypted database, broad file access)

Recommendations for Users:

1. Use only on non-rooted devices to protect local database
2. Keep small balances in the wallet due to centralized infrastructure
3. Be cautious when using mini-apps from unknown sources
4. Review and minimize granted permissions when possible
5. Keep the app updated to receive security patches
