Is Lampa-1.12.4.apk safe?
No engine detected the established APK, while an isolated direct-IP heuristic remains uncorroborated and completed runtime evidence is unavailable.
None of 73 engines flagged this APK, including 16 tier-1 engines reporting no detection, and it has substantial historical prevalence. A direct-IP heuristic introduces limited caution, but there is no corroborating offensive technique, malicious child, or engine detection; completed runtime observation and comprehensive host-reputation coverage are unavailable.

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.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
None of 73 engines flagged this APK, including 16 tier-1 engines reporting no detection, and it has substantial historical prevalence. A direct-IP heuristic introduces limited caution, but there is no corroborating offensive technique, malicious child, or engine detection; completed runtime observation and comprehensive host-reputation coverage are unavailable.
Static scanning produced no detections from 73 engines, including no tier-1 flags. The APK has been submitted 625 times by 549 sources, reducing concern that it is an obscure newly introduced sample. One heuristic noted direct-IP communication, but that signal is not supported by offensive techniques, engine labels, or a known malicious child. No completed sandbox run is available, so execution behavior cannot be characterized from this evidence. Host-reputation inspection covered only part of the observed contacts, and all five dropped-child verdicts remain unknown, leaving some residual uncertainty.
What We Detected
None of 73 antivirus engines flagged the APK, and 16 tier-1 engines reported no detection. The file also has established prevalence, with 625 submissions from 549 sources.
Threat Behavior
A medium-severity direct-IP heuristic fired after contacts including 99.84.152.8 and 140.82.121.6. However, no offensive-only MITRE techniques were identified, no child was identified as malware, and there was no completed sandbox run. Host-reputation inspection covered only a subset of the observed contacts, while all five dropped-child verdicts remain unknown.
What To Do Now
Obtain the APK from the project's official release channel and verify its hash before installation. Keep Android security protections enabled, review requested permissions, and avoid installing it if the source or expected version cannot be confirmed.
Where this verdict could be wrong4 caveats
- MalwareTips.Synth.DirectIpC2 fired because the APK contacted multiple IP addresses directly, which warrants caution despite lacking detection or offensive-technique corroboration.
- behaviour.sandboxCount=0 means no completed runtime observation can validate the app's execution behavior.
- contactedHosts.inspected=4 does not cover all 15 distinct contacted IPs and 4 URLs, so no complete host-reputation result is available.
- All five inspected dropped children have unknown verdicts, limiting assurance about dynamically generated code-cache artifacts.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/73 engines reported malicious or suspicious results.
- 16 tier-1 engines reported no detection.
- The APK has 625 submissions from 549 sources.
- No offensive-only techniques were identified.
- No inspected child was identified as malicious.
- Direct-IP communication triggered MalwareTips.Synth.DirectIpC2.
- No completed runtime observation is available.
- Host-reputation coverage is incomplete for the observed contacts.
- Five dropped child artifacts remain unclassified.

Detection sources at a glance
The available sources did not agree on a named threat category.
Available reference checks returned no match, but at least one source was unavailable. This is not a clean result.
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.
