Is HappyMod-3-4-5.apk safe?
No antivirus engine detected this widely submitted APK, and its completed sandbox run showed no offensive techniques or malicious runtime verdict.
All 75 antivirus engines returned without a detection, including 17 tier-1 engines. One sandbox run found only common application networking, but the app contacted many advertising and download endpoints, and its extracted child was not independently classified.

Before installing
Install it only from Google Play, the developer's official store, or another source you independently trust.
If you already installed it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines returned without a detection, including 17 tier-1 engines. One sandbox run found only common application networking, but the app contacted many advertising and download endpoints, and its extracted child was not independently classified.
The strongest evidence is complete detection silence: 0 of 75 engines flagged the APK, including all 17 tier-1 engines. A completed sandbox run produced no malicious verdict and no offensive-only techniques, although it did observe encrypted web communication and application discovery activity. The file is broadly distributed, with 3,194 sources and 4,843 submissions, which lowers the likelihood of an obscure newly introduced threat. None of the external research sources matched the sample, and the inspected dropped child was not identified as malicious. Some caution remains because the APK contacted many advertising and download services, host-reputation coverage was incomplete, and the dropped child remains unclassified.
What We Detected
No antivirus engine flagged the APK: 0 of 75 reported a malicious or suspicious result, and all 17 tier-1 engines returned without detection. External research checks also produced no MalwareBazaar, YARAify, or CIRCL match. The sample has broad exposure, with 3,194 sources accounting for 4,843 submissions.
Threat Behavior
One completed sandbox run produced no malicious runtime verdict and recorded no offensive-only techniques. It did observe common Android application networking represented by T1071, T1429, and T1573, including connections to crash reporting, advertising, analytics, configuration, and download infrastructure. The host-reputation cache found no malicious or suspicious entries among 22 inspected hosts, but it did not cover every distinct observed contact. One extracted child was inspected without a malicious finding, though it remains unclassified.
What To Do Now
Use the APK only if it came from a source you trust and its requested permissions match its advertised purpose. Keep Android security protections enabled, avoid granting unnecessary permissions, and prefer an official application store or the developer's verified release channel when available.
Where this verdict could be wrong3 caveats
- The APK contacted numerous advertising, analytics, configuration, and download endpoints, including a direct IP URL and a remote SWF download URL; this expands its network exposure despite no cached reputation hits.
- droppedChildren.rollup records 1 unknown child, so the extracted file was not independently established as benign.
- contactedHosts.inspected=22 does not cover every distinct observed domain, IP, and URL, so no complete host-reputation result is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 engines reported a malicious or suspicious result.
- All 17 tier-1 engines returned without detection.
- One sandbox run produced no malicious verdict and behaviour.offensiveCount=0.
- droppedChildren.hasMaliciousChild=false.
- No MalwareBazaar, YARAify, or CIRCL match was found.
- The APK contacted multiple advertising, analytics, configuration, and download endpoints.
- Observed URLs include a direct-IP statistics endpoint and a remote SWF download path.
- The sole dropped child remains unclassified.
- Host-reputation coverage did not include every distinct observed contact.
- The APK contains native ELF components and uses reflection, increasing inspection complexity.
Install only from a trusted distribution channel and review the app's permissions before use. Keep device security protections enabled and remove the app if it produces unexpected downloads, advertisements, or network activity.
