Maybank QRPayBiz
Malayan Banking Berhad · Build 4.4.1
Static checks identify review items, not a guarantee of safety.
Overview
4 finding categories to review
Maybank QRPayBiz (com.maybank.quickmerchant) scored grade A, 91 out of 100, in a static scan of version 4.4.1 on 2026-10-08. It has no high or critical findings, and 4 lower-severity finding categories across 7 occurrences. 1 tracking SDK is 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.

mediumcom.squareup.okhttp3:okhttp 3.12.12 — 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.
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.
- 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.
lowFirebase Storage bucket reference2 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.
- Evidence
- 2 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.

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 Storage
Requested permission inventory (35)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Android ID, Device ID / IMEI, Hardware MAC address) with 1 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.

Embed this grade
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/0d962053-5b66-453b-9056-fb149cdd7d86/findings.sarif (also coverage.json and proof.json).
