Is app-release.apk safe?
No antivirus engine detected this moderately prevalent APK, while the unverified direct-IP activity remains a limited caution rather than corroborated malware evidence.
None of 75 antivirus engines flagged the APK, including all 17 tier-1 engines, and external intelligence produced no malware matches. Seven recorded IP contacts deserve some caution, but no sandbox execution or complete host-reputation check is available to show that those connections were harmful.

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.
None of 75 antivirus engines flagged the APK, including all 17 tier-1 engines, and external intelligence produced no malware matches. Seven recorded IP contacts deserve some caution, but no sandbox execution or complete host-reputation check is available to show that those connections were harmful.
The strongest evidence is broad detection silence: 0 of 75 engines flagged the file, and all 17 tier-1 engines reported no detection. The APK has appeared in 145 submissions from 140 sources over 170 days without acquiring a malware family label. Researcher-curated sources also returned no matching malware record or YARA rule. A heuristic noted seven direct-IP contacts, but heuristics alone do not establish command-and-control activity. Because sandboxCount is zero and contactedHosts is null, there is no completed runtime observation or comprehensive host-reputation result for those addresses.
What We Detected
None of 75 antivirus engines flagged the APK, including all 17 tier-1 engines. External intelligence found no MalwareBazaar record, CIRCL hit, or YARAify rule match, and the file has been submitted 145 times by 140 sources.
Threat Behavior
A medium-severity heuristic identified seven direct-IP contacts and the APK is tagged as obfuscated. However, behaviour.sandboxCount=0 means there was no completed runtime observation, and contactedHosts=null means no complete reputation result is available for those addresses. No offensive-only MITRE techniques or malicious dropped child were identified.
What To Do Now
Obtain the APK from its official developer or trusted application store and verify that its hash matches the expected release. Keep Android security protections enabled and avoid granting permissions unrelated to the application's stated purpose.
Where this verdict could be wrong2 caveats
- The APK carries the file.tags value "obfuscated"; obfuscation can conceal code, although it is also common in ordinary Android applications.
- MalwareTips.Synth.DirectIpC2 fired for seven external IP contacts, but no completed sandbox run or host-reputation cross-check is available to establish their purpose.
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 antivirus engines detected the APK
- 17/17 tier-1 engines reported no detection
- externalIntel.yaraify.ruleCount=0
- externalIntel.malwareBazaar.hit=false
- 140 sources submitted the file 145 times over 170 days
- file.tags includes obfuscated
- MalwareTips.Synth.DirectIpC2 fired for seven external IP contacts
- behaviour.sandboxCount=0, so runtime behavior was not completed
- contactedHosts=null, leaving contacted-IP reputation unverified
Use the APK only if it came from the official developer or a trusted store, and verify its SHA-256 before installation. Keep Android security protections enabled.

Signatures and behavior heuristics
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
