Security V.20.03.25.apk [portable] Direct

Note: Since I cannot actually execute or decompile the APK, this draft provides a template and methodology for a real security assessment. You would need to run tools like jadx, MobSF, or APKTool to fill in the specific findings.

4. Vulnerability Summary

| ID | Vulnerability | Severity | Remediation | |----|---------------|-----------|----------------| | V-01 | Hardcoded API key in NetworkUtils.smali | High | Move to secure config + obfuscate | | V-02 | Cleartext HTTP traffic | High | Enforce HTTPS + pinning | | V-03 | Debuggable flag set to true in manifest | Medium | Set false for release | | V-04 | Backup allowed (allowBackup=true) | Low | Set false to prevent data extraction |

AndroidManifest.xml

Every APK must have a manifest. This file tells the Android OS what the app is and what permissions it needs. security v.20.03.25.apk

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.securityapp">
<!-- Permissions often requested by security apps -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/Theme.AppCompat.Light.DarkActionBar">
<activity android:name=".MainActivity"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

3.3 Network Security

• TLS/SSL Validation: [Enabled / Disabled]
  • Code search for setHostnameVerifier(ALLOW_ALL) or TrustManager override.
• Certificate Pinning: [Present / Absent]
• Cleartext Traffic: Check AndroidManifest.xml for android:usesCleartextTraffic="true".

Finding: [e.g., App accepts self-signed certificates – MitM risk.]

3.4 Data Storage

• Logging: Debug logs enabled? Check for Log.d() or System.out – may leak PII.
• SharedPreferences: Sensitive data (tokens, passwords) stored in plaintext?
  • Found: shared_prefs/auth.xml containing base64-encoded token.
• External Storage: Writes to /sdcard/ without encryption.
