Is OrcaSlicerWaveOverhangs_Windows_Installer_V0.4.0.exe safe?
Unsigned NSIS installer with zero detections and medium prevalence.
No engines flagged the file. One sandbox run showed only ambient and one dual-use technique. Two of three similar imphash samples were previously rated safe.

Before installing
Install it only when it came from the developer's official site or an official app store.
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.
No engines flagged the file. One sandbox run showed only ambient and one dual-use technique. Two of three similar imphash samples were previously rated safe.
Zero malicious detections across 74 engines, including 16 tier-1 engines, removes any engine-based risk. The file is unsigned, which is common for small open-source installers. Sandbox behaviour is limited to installer extraction and a single dual-use access token technique. Two of three prior imphash matches were rated safe under similar conditions, supporting a benign classification.
What We Detected
74 engines scanned the 133 MB NSIS installer; none returned a malicious or suspicious result. The binary is unsigned and contains no packers. Sandbox execution wrote temporary NSIS plug-ins and scheduled a single Windows task, all consistent with a legitimate installer.
Threat Behavior
One sandbox recorded T1134 (access token manipulation) alongside 14 ambient techniques such as system-information discovery and registry queries. no complete contacted-host reputation result was available, dropped malicious children, or external-intel hits were observed.
What To Do Now
The installer can be executed if obtained from the official Orca Slicer project site. Keep Windows Defender and other endpoint protection enabled; no additional steps are required.
Where this verdict could be wrong1 caveat
- similarHashes[0].verdict=suspicious (matchKind=imphash, reasonCode=ai:borderline_mixed_signals) — weak counter-signal because signerCoMatch=false.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero detections across 74 engines
- Medium prevalence with 15 prior submissions
- No malicious sandbox verdict or dropped children
The file shows no malicious indicators and can be considered safe when downloaded from the legitimate project source.
