Overview

Analysis recorded

3 finding categories to review

IoT Assistant (io.iotprivacy.iotassistant) scored grade A, 92 out of 100, in a static scan of version 2.2.3 on 2026-10-08. It has no high or critical findings, and 3 lower-severity finding categories across 3 occurrences. 3 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.

mediumcom.squareup.okhttp3:okhttp 3.12.13 — 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.
Open in all findingsRequest a correction
lowBackground location access with advertising SDKs present1 occurrence

Interpretation & review guidance

The app can access location in the background (even when closed) and also ships advertising/attribution SDKs. Background location is a heightened-scrutiny area for Google Play and privacy regulators; confirm it is essential and disclosed, and that location isn't shared with ad networks.

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.

  • Precise location, Approximate location, Background location requested while 2 ad/attribution SDK(s) are present (Google AdMob, Adjust) — location commonly feeds ad targeting.
  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 2 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.
