Is ultracopier-windows-7-64-3.0.2.3-setup.exe safe?
Unsigned NSIS installer with a single low-trust detection and no tier-1 or sandbox malicious signals.
73 engines scanned the file; only one low-trust engine flagged it. No tier-1 detections, no sandbox malicious verdict, and no malicious dropped children were observed.

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.
73 engines scanned the file; only one low-trust engine flagged it. No tier-1 detections, no sandbox malicious verdict, and no malicious dropped children were observed.
The single detection originates from a low-trust engine and is not corroborated by any tier-1 engine. The file is an unsigned installer that exhibits typical NSIS behaviour and drops only benign temporary files. Similar-hash matches are imphash-only and therefore weak. The absence of tier-1 consensus and sandbox malicious verdicts supports a safe classification.
What We Detected
73 engines contributed results; one low-trust engine (Trapmine) returned a generic suspicious label. No tier-1 engine flagged the sample. The file is an unsigned 64-bit Windows installer (NSIS) with high entropy sections but no packer signature.
Threat Behavior
Sandbox execution showed only ambient techniques and one direct-IP connection to 162.159.36.2; no malicious sandbox verdict was issued. Four dropped children were inspected and none were malicious. No persistence mechanisms or registry modifications were recorded.
What To Do Now
The file can be executed if obtained from the official Ultracopier project site. Keep endpoint protection enabled and verify the download checksum against the publisher's published value.
Where this verdict could be wrong1 caveat
- similarHashes[1].verdict=suspicious (neshta) on imphash match — weak 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.
- tier1Malicious=0
- hasMaliciousSandboxVerdict=false
- droppedChildren.hasMaliciousChild=false
The evidence supports treating the file as safe; no further action is required beyond normal verification of the download source.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
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.
