Verdict Safe
Is vs_
A verified Microsoft signature, zero detections across 75 engines, and five matching signer precedents outweigh uncorroborated sandbox technique mappings.

Why we think so
2 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The executable carries a verified Microsoft Corporation signature, and none of the 70 antivirus engines that checked it flagged it.
No antivirus engine flagged the sample: the result is 0 of 75, including no major detections. Its signature verifies to Microsoft Corporation, a curated trusted publisher, and 15 of 16 historical samples associated with that signer were rated safe. Five signer-matched prior files also received safe decisions, strengthening the commercial-installer interpretation. One sandbox mapped activity to T1055, T1485, and surfaced the Windows password store-related activity, but it did not issue a malicious sandbox finding and no inspected child was identified as malicious.
What We Detected
The file is a signed Windows executable named vs_setup.exe. Its Authenticode signature verifies to Microsoft Corporation, the recognised-publisher check is true, and 0 of the 70 antivirus engines that checked it reported a detection. Five previous signer-matched files received safe decisions, while the signer's recorded history is 15 safe results out of 16 samples.
Threat Behavior
These are concerning mappings, but the sandbox did not issue a malicious finding, and none of 10 inspected dropped files was identified as malicious; their individual verdicts remain unknown. The executable also contacted 162.159.36.2 directly, but no complete host-reputation result is available because the contacted-host check was not saved.
What To Do Now
Use the file only if it came from Microsoft's official download channel and Windows still shows a valid Microsoft Corporation signature. Keep security software enabled, and redownload the installer if its origin or signature cannot be verified.
Where this verdict could be wrong5 caveats
- The sandbox's offensive-technique list includes T1055, T1485, and T1486, and one of our behaviour rules associated observed process activity with the Windows password store.
- The file is rare and newly seen: this exact hash was submitted once and first observed on Sep 8, 2026.
- The sample contacted 162.159.36.2 directly, but the missing contacted-host reputation result means no completed reputation cross-check is available.
- droppedChildren inspected 10 files without identifying a malicious child, but all 10 individual child verdicts are unknown.
- The signer-history record includes 1 malicious result among 16 Microsoft-signed historical samples.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0 of the 70 antivirus engines that checked it reported a detection.
- The Microsoft Corporation signature is verified.
- Microsoft matched the curated trusted-publisher list.
- Five of five signer-matched prior decisions were safe.
- No malicious sandbox verdict or malicious file it created was recorded.
- The exact hash is and has only one recorded submission.
- Sandbox mappings included T1055, T1485, and T1486.

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.

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
Rarely uploaded, and first seen more than two weeks ago. Often niche legitimate software or internal tooling; not a strong malware signal on its own.
