Why we think so
0 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
This DLL is the Unity game engine player runtime, validly signed by Unity Technologies ApS. None of the 71 antivirus engines that checked it flagged it, it appears in a known-good software reference set, and it has been shared by over 500 sources since first seen on Nov 20, 2021. The combined sandbox verdict was clean.
The file carries a verified code signature from Unity Technologies ApS, a publisher on our curated trusted list. It is listed in a known-good software reference set and has been submitted by 503 distinct sources since first seen on Nov 20, 2021. Across three sandbox runs the combined verdict was clean, with no high-risk techniques, no named injection target and only background network traffic. A previous file from the same signer was also judged clean.
What We Detected
None of the 71 antivirus engines that checked it flagged this DLL. It is validly signed by Unity Technologies ApS, matches a known-good software reference entry, and has been seen from 503 sources since Nov 20, 2021. The antivirus analysis found no packer or high-entropy code.
Threat Behavior
The combined sandbox verdict was clean. The only activity was a Unity player log written under the user's LocalLow folder, typical of a Unity game starting. The only network contact was the analysis machine's own background traffic.
What To Do Now
No action is needed. This file is a normal component of games built with the Unity engine. Keep your security software enabled and obtain games from their official stores.
Where this verdict could be wrong1 caveat
- The sandbox mapped one process-injection technique, but no target process was recorded, so this is a generic label seen on many clean files.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

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.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
