Monster Math 2: Fun Kids Games
Makkajai: Math Games for 1st, 2nd, 3rd, 4th grade · Build 1402
Static checks identify review items, not a guarantee of safety.
Backend checks: 4 unauthenticated read checks against backends referenced in this build — 4 answered. Each check describes one request at the recorded scan time and does not establish the backend's current state.
Overview
1 high or critical finding category to review
Monster Math 2: Fun Kids Games (com.makkajai.monstermath2free) scored grade F, 0 out of 100, in a static scan of version 1402 on 2026-11-02. It has 1 high or critical finding category of 4, across 7 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. 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.

criticalAmazon S3 bucket reference — confirmed publicly readable4 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
- 4 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- 4 historically verified occurrences at the recorded scan time. Current reachability is not established.
mediumcom.squareup.okhttp3:okhttp 4.3.1 — 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.

mediumExported content provider without permission1 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.

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).

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Requested permission inventory (6)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Android ID, Device ID / IMEI) with 1 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
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/3c063e22-cfd8-45c7-bc0b-e5698f442477/findings.sarif (also coverage.json and proof.json).
