Static checks identify review items, not a guarantee of safety.
Overview
5 finding categories to review
Messenger (com.facebook.orca) scored grade B, 85 out of 100, in a static scan of version 580.0.0.49.91 on 2026-09-30. It has no high or critical findings, and 5 lower-severity finding categories across 7 occurrences. 4 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
mediumcom.squareup.okhttp3:okhttp 3.14.9 — CVE-2021-03411 occurrence
Interpretation & review guidance
The app bundles a third-party library whose declared version matches a public security advisory (CVE). This is flagged from the version the library itself ships and a curated advisory list — confirm exploitability in your context and update the dependency to the fixed version. It is not a proof of live exploitation.
- 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.
mediumShort signing key (RSA 1024-bit)1 occurrence
Interpretation & review guidance
The signing key is shorter than the modern 2048-bit RSA minimum. Short keys are cryptographically weaker; a release should re-key to at least RSA-2048 (or an EC key).
- 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.
lowApplication 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.

lowFirebase Realtime Database reference1 occurrence
Interpretation & review guidance
A Firebase Realtime Database URL. Nearly every app that uses Firebase ships one. It's only an exposure if the database rules are world-readable — that's what live verification checks.

lowGoogle API key (client-shipped; restriction unverified)3 occurrences
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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Precise location Approx. location Camera Microphone Contacts Phone state Calendar Accounts Storage Draw over other apps
Requested permission inventory (87)
Data collection & flow (privacy signal, not part of the grade)
- Precise location, Approximate location requested while 2 ad/attribution SDK(s) are present (Google AdMob, Meta Audience Network) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +2 more) with 4 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- Calendar, Camera, Contacts, Microphone, Personal info, Phone, 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.
Data Safety: declared vs observed (Play label vs our analysis)
We compare the developer's Google Play Data Safety declaration with what the binary can actually do (permissions it requests, identifier APIs and third-party SDKs it ships). A mismatch is a capability signal to confirm — a requested permission is not proof of collection.

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/a4a87662-4558-4e3f-a9d5-4af21c678c79/findings.sarif (also coverage.json and proof.json).
