Guarda: Crypto Bitcoin Wallet
GUARDA · Build 3.2.8
Static checks identify review items, not a guarantee of safety.
Overview
3 high or critical finding categories to review
Guarda: Crypto Bitcoin Wallet (com.crypto.multiwallet) scored grade F, 0 out of 100, in a static scan of version 3.2.8 on 2026-10-22. It has 3 high or critical finding categories of 8, across 68 occurrences. 2 findings were 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. 6 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
criticalAmazon S3 bucket reference — confirmed publicly readable36 occurrences
Interpretation & review guidance
A reference to an Amazon S3 bucket. Using cloud storage is normal — the risk exists only if the bucket allows anonymous listing/read, which requires a separate authorized assessment.
Reference: CWE-200 · CWE-284 · MASVS-STORAGE-2 — what the control asks for, and other apps with the same finding.
- Evidence
- 36 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- 11 historically verified occurrences at the recorded scan time. Current reachability is not established.
criticalGoogle Cloud Storage reference — confirmed publicly readable21 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).
Reference: CWE-200 · CWE-284 · MASVS-STORAGE-2 — what the control asks for, and other apps with the same finding.
- Evidence
- 21 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- 1 historically verified occurrence at the recorded scan time. Current reachability is not established.
highAWS access key ID1 occurrence
Interpretation & review guidance
An AWS access key ID. This is high-risk if the matching secret key is also embedded and the key isn't tightly scoped/rotated. A key ID alone is not proof of a usable credential.
Reference: CWE-798 · MASVS-STORAGE-1 — what the control asks for, and other apps with the same finding.
- 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.

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.

lowFirebase Storage bucket reference1 occurrence
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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Precise location Approx. location Camera Storage
Requested permission inventory (21)
Data collection & flow (privacy signal, not part of the grade)
- Approximate location, Precise location requested while 1 ad/attribution SDK(s) are present (Google AdMob) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +1 more) with 4 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/c8c7371d-efa1-4cb5-a596-a289e8833e1b/findings.sarif (also coverage.json and proof.json).
