Is MalumMenu-3.3.0-Steam-Itch.zip safe?
No antivirus engine identified malware, and broad prevalence supports legitimacy, though process-injection and defense-impairment technique mappings justify retaining normal endpoint protection.
None of 74 engines flagged the archive, including no tier-1 detections, and it has been submitted 671 times by 547 sources. One sandbox mapped process injection, archiving, and defense-impairment techniques, but produced no malicious conclusion; obtain the archive from its official release channel and keep endpoint protection enabled.

Before opening or extracting
Open or extract it only when its sender or download source has been independently verified.
If you already opened or extracted 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 74 engines flagged the archive, including no tier-1 detections, and it has been submitted 671 times by 547 sources. One sandbox mapped process injection, archiving, and defense-impairment techniques, but produced no malicious conclusion; obtain the archive from its official release channel and keep endpoint protection enabled.
The antivirus results are strongly reassuring: 0 of 74 engines reported a malicious or suspicious result, and 13 tier-1 engines reported no detection. The archive also has substantial prevalence, with 671 submissions from 547 sources, and no external intelligence source identified a malware family. One completed sandbox run mapped T1055, T1560, and T1562.001, including unusual rundll32 execution involving temporary .NET libraries, but it did not issue a malicious sandbox verdict. Ten dropped files were inspected without a confirmed malicious child, although their individual verdicts remain unknown. No network contacts were recorded during that run, but contacted-host reputation was not checked or saved, so no complete host-reputation conclusion is available. Overall, the static consensus and prevalence outweigh the uncorroborated behavioral heuristic, while still supporting cautious sourcing and execution.
What We Detected
None of 74 antivirus engines flagged the ZIP archive, and engines.tier1Malicious=0. Thirteen tier-1 engines, including Microsoft, BitDefender, ESET-NOD32, Emsisoft, Fortinet, and Avira, reported no detection. The file also shows broad circulation, with prevalence.uniqueSources=547 and prevalence.timesSubmitted=671.
Threat Behavior
One completed sandbox run mapped T1055, T1560, and T1562.001. The strongest concern is rundll32 launching temporary .NET DLL paths, which triggered the MalwareTips.Synth.ProcessInjection heuristic; however, that mapping does not prove the injection method or intent, and behaviour.hasMaliciousSandboxVerdict=false. Ten dropped children were inspected without a confirmed malicious child, but each child still has an unknown individual verdict. No domains, IPs, or URLs were recorded during the run; contactedHosts=null means a complete host-reputation check is unavailable.
What To Do Now
Use the archive only if it came from the project's official Steam, itch.io, or official developer release channel. Keep antivirus and endpoint protection enabled, scan the extracted executable before launch, and avoid running it with administrator privileges unless the publisher explicitly documents that requirement.
Where this verdict could be wrong4 caveats
- The MalwareTips.Synth.ProcessInjection heuristic fired on T1055-related rundll32 execution from a temporary .NET directory, which warrants caution despite the absence of engine detections.
- The sandbox also mapped T1562.001 and T1560, techniques associated with defense impairment and archiving, although it issued no malicious verdict.
- All 10 inspected dropped children have unknown individual verdicts, so droppedChildren.hasMaliciousChild=false does not establish that every extracted component is benign.
- contactedHosts=null means no complete host-reputation cross-check 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.
- 0/74 antivirus engines reported malicious or suspicious results.
- engines.tier1Malicious=0, with 13 tier-1 engines reporting no detection.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false after 10 inspections.
- 547 sources submitted the sample 671 times.
- One sandbox mapped process injection activity to MITRE T1055.
- The runtime evidence also mapped T1562.001 and T1560.
- rundll32 executed DLLs from a temporary .NET directory.
- All 10 dropped-child verdicts remain individually unknown.
- No complete contacted-host reputation result is available.
Download only from the official project channel, scan the extracted executable, and keep endpoint protection enabled. Avoid elevated execution unless the publisher documents a legitimate need.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
