Finding evidence
Open a category to review its occurrences. Printing includes all categories and occurrences.
Application data is backup-enabled · info · 1 occurrence
Backup is on by default on Android; this manifest states it explicitly. If the app stores sensitive local data, define dataExtractionRules/fullBackupContent to exclude it, or set android:allowBackup=false.
CWE-530 · CWE-312 · MASVS-STORAGE-1 · MASVS-STORAGE-2
android:allowBackup="true"
Google API key (client-shipped; restriction unverified) · low · 1 occurrence
Restrict the API key (application + API restrictions in Google Cloud Console); a client-shipped key is public, so restriction is the control.
CWE-798 · MASVS-STORAGE-1
AIza•••••••• (21–40 chars, redacted)
Short signing key (RSA 1024-bit) · medium · 1 occurrence
Use an RSA key of at least 2048 bits or an EC P-256 key for signing.
CWE-326 · MASVS-CRYPTO-1
RSA-1024
