Verdict Suspicious
Is Setup.
One generic grayware detection lacks runtime or intelligence corroboration, but the unsigned executable is too new and uncommon to establish confidently.
Read the whole reasonShow less
Why Suspicious? One antivirus engine (CrowdStrike) flags it; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
If it came from a link, an attachment or a stranger, delete it.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't install it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already installed it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
4 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Only 1 of the 71 antivirus engines that checked it flagged this installer, using a generic grayware label, while major engines remained silent. The test run found no high-risk technique or named injection target, but the file is unsigned and leaving its publisher and longer-term reputation unresolved.
CrowdStrike was the only engine to flag the sample, and its label describes generic grayware rather than a named malware family. The observations from the test run produced no malicious sandbox assessment, no named injection target, and no sample-generated network contact. The mapping lacks the artifact needed to establish process injection and therefore carries no adverse weight. No malicious host, malicious child, public sample-database listing, or malware-specific YARA rule corroborates the detection. However, the executable has no signature and has been submitted by only one source since it was first observed, so there is not enough provenance or history for a firm benign conclusion. Similar import hashes offer mixed, weak context because none shares a verified publisher with this sample.
What We Detected
Only 1 of the 71 antivirus engines that checked it flagged the executable. CrowdStrike used a generic grayware label, while no major antivirus engines identified malware and no engine consensus named a family.
Threat Behavior
Five completed sandbox runs produced no malicious assessment, no high-risk technique, and no named process-injection target. The T1055 mapping was recorded without an injection artifact and does not demonstrate actual injection. The sole observed domain was identified as analysis-environment background traffic, and the complete host check found no malicious or suspicious host.
Additional Context
No malware-specific YARA rule or public sample-database entry matched the hash. No inspected child was harmful, and one identified child matched a known-software reference entry. Against that, the executable is unsigned, and has very limited prevalence, so its origin cannot be authenticated.
What To Do Now
Obtain the installer from the software publisher's official release channel and verify its checksum or signature before running it. Keep security software enabled and avoid execution if the source cannot be independently verified.
Where this verdict could be wrong3 caveats
- CrowdStrike identified the executable as grayware, which may indicate unwanted installer behavior even though no other engine corroborated it.
- The executable is unsigned and only recently observed, so its publisher and longer-term reputation cannot be established.
- Four prior files sharing this import hash received cautionary assessments, although the shared hash may reflect a common installer framework rather than common authorship.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1 of the 71 antivirus engines that checked it flagged the file, and no major antivirus engines detected it.
- Completed the test run produced no malicious assessment or high-risk behavior.
- No named injection target was observed.
- No malicious host or harmful inspected child was identified.
- No malware-specific community rule or public sample-database entry matched the hash.
- The executable is unsigned, so its publisher cannot be authenticated.
- It was first observed very recently and has been submitted by only one source.
- CrowdStrike reported a generic grayware detection.
- Several files sharing the same import hash previously received cautionary assessments, though this may reflect a shared installer framework.

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Ran commands or a script on the test computer.
Moderate concern: Checked whether it was running on a test computer.
Note: Read the user name of the test computer.
Note: Read basic details of the test computer, such as its Windows version.
Note: Looked through folders on the test computer (most installers do this).
Note: Loaded extra code modules while running.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.
Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

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
Barely seen in the wild and first surfaced recently. 1 antivirus detection make that low prevalence materially relevant, but rarity alone is not proof of malware.
