Is SecurityTest_Powershell.ps1 safe?
No antivirus engine detected this small PowerShell script, although its newness and absent runtime analysis warrant normal caution before execution.
All 75 antivirus engines returned no malicious or suspicious result, including 17 high-trust engines. The hash is newly observed, unsigned, and lacks completed sandbox analysis, so inspect the script's 327-byte contents and confirm its source before running it.

Before running
Run it only when it came from the developer's official site or another source you independently trust.
If you already ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines returned no malicious or suspicious result, including 17 high-trust engines. The hash is newly observed, unsigned, and lacks completed sandbox analysis, so inspect the script's 327-byte contents and confirm its source before running it.
Static scanning produced no detections from 75 antivirus engines, with all 17 reporting high-trust engines remaining silent. Available external intelligence also produced no known-malware hit, although the researcher-rule lookup timed out. No sandbox run completed, so the script's runtime actions were not observed, and no complete contacted-host reputation result is available. The hash has only one submission and no established publisher history, which limits confidence. Similar-file history is favorable but weak because all five matches are based only on file type.
What We Detected
No malicious or suspicious result was reported by any of 75 antivirus engines. This includes high-trust products such as BitDefender, ESET-NOD32, Kaspersky, Microsoft, and Avast. Available CIRCL and MalwareBazaar checks found no matching record, while the YARAify check timed out.
Threat Behavior
No completed sandbox observation is available because behaviour is null. The contacted-host cross-check was also not completed or saved, so no conclusion can be drawn about network destinations. The sample is a 327-byte unsigned PowerShell script with only one recorded submission.
What To Do Now
Open the script in a text editor and verify every command against its expected security-test purpose before execution. Obtain it from a trusted source, keep endpoint protection enabled, and test it in an isolated environment if its origin or contents are uncertain.
Where this verdict could be wrong3 caveats
- The PowerShell script is unsigned and only 327 bytes, while prevalence.classification=rare_new indicates it was first observed in a single submission.
- externalIntel.yaraify is unavailable because the lookup timed out, leaving one researcher-rule source unchecked.
- Five prior safe results are only file-type matches, not signer, code, or imphash matches.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines reported a detection
- 17 high-trust engines reported no detection
- No MalwareBazaar or CIRCL hit
- No confirmed hacktool or test-file label
- Five file-type-level similar samples previously received safe verdicts
- Newly observed hash with one source and one submission
- Unsigned PowerShell script
- No completed sandbox observation
- No complete contacted-host reputation result
- YARAify lookup timed out
Review the script as plain text and verify its origin before running it. Keep endpoint protection enabled and use an isolated test environment when provenance is uncertain.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Run it only when it came from the developer's official site or another source you independently trust.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
