Is my-mammott.apk safe?
No antivirus engine detected this long-established Android package, and neither external intelligence nor inspected child evidence supplied corroborating malware indicators.
All 74 antivirus engines returned without a malicious or suspicious detection, including 16 tier-1 engines reporting no detection. The APK has circulated since 2017 across 116 sources, although no completed sandbox run is available and host-reputation coverage is incomplete.

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 74 antivirus engines returned without a malicious or suspicious detection, including 16 tier-1 engines reporting no detection. The APK has circulated since 2017 across 116 sources, although no completed sandbox run is available and host-reputation coverage is incomplete.
The strongest evidence is the complete absence of malicious or suspicious detections across 74 engines, with no tier-1 family consensus. The APK is also well established, having appeared in 140 submissions from 116 sources since 2017. Research feeds supplied no YARA rules, known-malware record, or named family, and the inspected child was not identified as malicious. A direct-IP heuristic and static tags such as obfuscation and reflection warrant caution, but they lack independent corroboration. Because sandboxCount is zero and host inspection did not cover every listed contact, runtime and network activity cannot be described as fully assessed.
What We Detected
No malicious or suspicious result appeared among 74 antivirus engines. Sixteen tier-1 engines reported no detection, and there was no malware-family consensus. The APK has been observed since 2017, with 140 submissions from 116 distinct sources, which supports an established software profile.
Threat Behavior
No completed sandbox run is available, so the listed Android techniques and network contacts are artifacts rather than confirmed runtime observations. A medium-severity direct-IP heuristic fired, and the package carries static tags for obfuscation, reflection, cryptography, and runtime modules. However, offensiveCount=0, no malicious child was identified, and external intelligence returned no matching YARA rules or known-malware record. Host-reputation inspection covered only part of the listed network contacts, so no complete network-reputation conclusion is available.
What To Do Now
Obtain the APK from the original developer or an established app store and verify its package identity before installation. Keep Android security protections enabled, especially when sideloading an older application.
Where this verdict could be wrong4 caveats
- triggeredHeuristics[0].rule=MalwareTips.Synth.DirectIpC2 fired at medium severity after direct-IP traffic, but this is not corroborated by an engine detection or completed sandbox verdict.
- file.tags includes obfuscated, reflection, crypto, and runtime-modules; these raise static complexity but are common in large Android games and do not independently identify malware.
- contactedHosts.inspected=7 provides only partial coverage of the 15 IP addresses and 7 URLs listed under behaviour, so host reputation is incomplete.
- droppedChildren.children[0] has source='unknown' and no verdict, leaving the extracted child unclassified.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 engines reported malicious or suspicious results.
- 16 tier-1 engines reported no detection and tier1Malicious=0.
- Observed since 2017 across 116 sources and 140 submissions.
- MalwareBazaar returned no hit and YARAify returned zero rules.
- droppedChildren.hasMaliciousChild=false.
- MalwareTips.Synth.DirectIpC2 fired at medium severity for direct-IP traffic.
- Static tags include obfuscated, reflection, crypto, and runtime-modules.
- behaviour.sandboxCount=0, so no completed runtime observation is available.
- contactedHosts.inspected=7 did not cover every listed IP address and URL.
- The single dropped child remains unclassified.
Use a trusted distribution source and verify the Android package name before installing. Keep endpoint and 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.
