Why we think so
0 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
No engines flagged the file. One sandbox run showed only routine and one dual-use technique. Two of three samples built with the same import table were previously rated safe.
Zero malicious detections across 74 engines, including 16 major antivirus 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 import-table fingerprint 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 techniques common in legitimate software such as system-information discovery and registry queries. no complete contacted-host reputation result was available, dropped malicious files it created, 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 security software enabled; no additional steps are required.
Where this verdict could be wrong1 caveat
- similarHashes[0].verdict=suspicious (matchKind=import-table fingerprint, reasonCode=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
