Verdict Safe
Is Instance
None of the 71 antivirus engines that checked it flagged this unsigned file, and the completed sandbox run found no confirmed harmful outcome despite an unverified mapping.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
The evidence supports normal use when the file came with software you intentionally installed from a trusted source. Keep security protection enabled and avoid using it if its origin is unknown or unexpected.
Good practice2 tips
We found nothing harmful in this file.
Run it only if it came from the developer's own website or an official app store.
Keep your antivirus and Windows updates switched on.

Why we think so
3 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 71 antivirus engines that checked it flagged the sample, including the major antivirus engines, and its single completed sandbox run returned clean. The mapping warrants some caution, but no injected target, malicious child, packed code, malware-specific research rule, or hostile contacted host corroborates it.
The strongest evidence is broad detection silence: none of the 71 antivirus engines that checked it flagged the file. One completed sandbox run returned clean and produced no dropped files or persistence indicators. It mapped T1055, but no target process was identified, so that mapping supports only possible injection rather than confirmed abuse. All three observed domains received host-reputation coverage, with no malicious or suspicious matches; two were explicitly attributed to sandbox background traffic. The unsigned status and limited prevalence reduce assurance, but the unpacked structure and absence of corroborating threat intelligence support a benign interpretation.
What We Detected
None of the 71 antivirus engines that checked it flagged the file, including all 17 major antivirus engines represented in the results. The executable is unsigned, but its code sections do not show high entropy and no packer was identified.
Threat Behavior
One completed sandbox run returned clean. It mapped possible process injection to MITRE T1055, but no injected target process was recorded, and there were no dropped files or persistence indicators. Reputation checks covered all three observed domains and found no malicious or suspicious matches; two of those domains were identified as analysis-environment background traffic.
What To Do Now
Use the file only if it came from the expected application or installation source. Keep security software enabled, and consider verifying the parent application's origin because the DLL has no digital signature.
Where this verdict could be wrong3 caveats
- The file is unsigned, so no publisher identity or established certificate history supports it.
- The sandbox mapped process injection, although it did not identify an injected process and returned a clean result.
- One import-table fingerprint-related file previously received a suspicious assessment, but the publisher did not match and the same import-table fingerprint can be shared by unrelated builds.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 71 antivirus engines that checked it flagged the file.
- The completed sandbox run returned clean and produced no dropped files or persistence indicators.
- All three observed domains were checked, with no malicious or suspicious reputation matches.
- No packer or high-entropy code was found.
- No malware-specific research rules or known malware-feed matches were found.
- The executable has no digital signature, so its publisher cannot be authenticated.
- A sandbox technique mapping indicated possible process injection, although no target process or harmful result was confirmed.
- The file has only moderate distribution history, with eight submitters and ten submissions.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
EvidenceT1055 (sandbox MITRE mapping)
Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
