Is OPLegendSetup.exe safe?
Only Cylance flagged this unsigned, newly observed installer, while tier-1 engines and one sandbox run provided no corroborating malware evidence.
Only 1 of 75 engines flagged the file, and that detection came from Cylance at the low-trust tier with a generic label. One sandbox run found no offensive techniques or malicious runtime verdict, but the installer is unsigned and newly observed, so it should come from a trusted source.

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.
Only 1 of 75 engines flagged the file, and that detection came from Cylance at the low-trust tier with a generic label. One sandbox run found no offensive techniques or malicious runtime verdict, but the installer is unsigned and newly observed, so it should come from a trusted source.
The scan shows one generic Cylance detection among 75 engines, with no tier-1 engine flagging the sample. This low-trust-only pattern is commonly associated with false positives. One completed sandbox run recorded ambient installer-like activity but no offensive techniques, malicious verdict, dropped malicious child, or network contacts. Independent intelligence sources did not identify the hash or match it with research rules. The main reservations are that the executable is unsigned, first observed today, and has only two submissions; the broad file-type similarity history is mixed and does not establish identity.
What We Detected
Cylance was the only detector among 75 engines, using the generic label “Unsafe.” No tier-1 engine reported malware, and there was no family consensus or confirmed hacktool label.
Threat Behavior
One completed sandbox run recorded 15 ambient techniques but no offensive techniques and no malicious sandbox verdict. It recorded no domains, IP addresses, URLs, dropped files, or persistence indicators. No complete contacted-host reputation result is available because contactedHosts was not checked or saved.
What To Do Now
The detection is likely a false positive, but the file is unsigned and newly observed. Download it only from the software publisher’s official channel, verify the SHA-256 value if one is published, and keep endpoint protection enabled while installing.
Where this verdict could be wrong3 caveats
- The executable is unsigned and newly observed, so publisher identity and established distribution cannot be verified.
- Cylance labelled the sample "Unsafe," although no other engine corroborated that generic detection.
- contactedHosts=null, so no complete contacted-host reputation result is available; the sandbox recorded no network contacts to cross-check.
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 75 engines flagged the file
- No tier-1 engine detections
- No offensive techniques in one sandbox run
- No malicious sandbox verdict
- No external-intelligence or YARA rule hits
- Unsigned Win32 executable
- First observed today with only two submissions
- Cylance generic detection
- No established signer history
- No complete contacted-host reputation result
Use the installer only if it came directly from the publisher’s official release channel, and verify its SHA-256 when possible. Keep antivirus and endpoint protection enabled.
