HiroVPN – Fast VPN Proxy
Wolle Apps · Build 1.21.0
Static checks identify review items, not a guarantee of safety.
Overview
3 high or critical finding categories to review
HiroVPN – Fast VPN Proxy (com.hiro.vpn) scored grade F, 0 out of 100, in a static scan of version 1.21.0 on 2026-10-03. It has 3 high or critical findings among 7 finding categories across 40 occurrences. One finding was confirmed live: an anonymous request reached a backend the app references and it answered without authentication. No credential was used and no stored data was read. 12 tracking SDKs are present in the package, which describes what ships, not what runs or what it sends. This is static analysis of a single build: it does not observe the app running and does not establish that any data is exposed.
Start with these findings
criticalGoogle Cloud Storage reference — confirmed publicly readable6 occurrences
Interpretation & review guidance
A Google Cloud Storage reference. Normal for apps that use GCS; risky only if the bucket is publicly listable/readable (live-verified).
- Evidence
- 6 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- 6 historically verified occurrences at the recorded scan time. Current reachability is not established.
highGoogle OAuth client secret1 occurrence
Interpretation & review guidance
A Google OAuth client secret. Shipping this in a mobile client is a misconfiguration — it can allow impersonation of the app's OAuth flow.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.
highTelegram bot API token1 occurrence
Interpretation & review guidance
A Telegram bot API token. Anyone with it can control the bot, read its messages and post as it — regenerate via BotFather.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.

lowExported content provider without permission (third-party library artifact, shared across 232 unrelated developers)1 occurrence
Interpretation & review guidance
An exported content provider declares no permission. Other apps on the device may reach it — verify it enforces access control internally; this flags the attack surface, not a confirmed leak.

lowFirebase Storage bucket reference29 occurrences
Interpretation & review guidance
A Firebase Cloud Storage bucket reference (the default <project>.appspot.com). Storing user files here is normal — it's only an exposure if the Storage security rules allow public read/list, which live verification tests.

lowGoogle API key (client-shipped; restriction unverified)1 occurrence
Interpretation & review guidance
Android apps are designed to ship Google API keys in the client; Google restricts them by app signing certificate + enabled API. This is only a problem if the key is left unrestricted — presence alone is expected, not an exposure.

infoApplication data is backup-enabled1 occurrence
Interpretation & review guidance
The app allows Android backups (android:allowBackup="true"). App data can then be extracted via adb backup on many devices — a concern if the app stores tokens or personal/health/payment data locally. Common and low-severity, but worth disabling for sensitive apps.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Camera Storage List installed apps
Requested permission inventory (24)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 9 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- Camera, Photos & files data requested with third-party analytics/ad SDKs present.
This maps what the app can access (permissions it requests, identifier APIs its code references) to the third parties bundled in it. It reflects capability and SDK presence — not proof that a specific value was transmitted.

The badge reads the latest recorded grade each time it is loaded, and links back to the full report so a reader can see the build it covers and what the scan could not see.
Grades can move when a new version is scanned or when a detector is corrected. If you would rather publish a grade that cannot change under you, link a signed Proof Capsule instead.
API users can request authenticated, scan-specific exports at /v1/scans/9c9ca739-3428-42fd-86a2-ee46f5dc3bc3/findings.sarif (also coverage.json and proof.json).
