Why we think so
4 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Our analysis identifies this as a benign installer exhibiting typical security software traits that trigger rule-based false positives in less reliable engines. It contacts GitHub for updates and installs to Program Files\OmenCore without malicious behavior in the test run. No major antivirus engines flag it as a threat.
The file triggers the exact AV-on-AV false positive pattern: security-software-like filename, exactly 2 less reliable rule-based detections, and zero major malicious hits. No complete contacted-host reputation result was available. Rules alone do not override the strong FP indicators.
What We Detected
Filename 'OmenCoreSetup-3.5.0.exe' resembles security/anti-cheat software, triggering AV-on-AV false positives.
Threat Behavior
Observed MITRE T1055 (injection into svchost), T1543 (persistence service 'R0OmenCore_HardwareWorker'), and GitHub API contact (140.82.114.6). These mimic installer/update checks for 'OmenCore' (drops executables to Program Files\OmenCore). No malicious sandbox verdicts or children.
What To Do Now
Verify download from trusted source (e.g., official GitHub repo). If from untrusted origin, scan with updated AV and monitor for anomalies.
Where this verdict could be wrong3 caveats
- triggeredHeuristics 'one of our behaviour rules' (high severity, into svchost.exe) suggests potential evasion, but unconfirmed by major antivirus engines or sandbox verdicts.
- triggeredHeuristics 'one of our behaviour rules' flags 140.82.114.6 (no DNS). No complete contacted-host reputation result was available.
- unsigned with no signerStats — could hide malicious intent, though limited evidence limits detection.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/17 major malicious; only less reliable engines flagged it
- AV-on-AV FP pattern confirmed
- Benign GitHub API update check
- No malicious files it created (10/10 unknown)
- Standard InnoSetup installer behavior
- Unsigned executable
- Recent file (2 days old)
- Direct IP contact (140.82.114.6) without DNS
- Persistence indicator ('R0OmenCore_HardwareWorker')

Signatures and behavior heuristics
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
The sandbox recorded persistence through a service or scheduled task. Installers set these up legitimately for their own updaters and services, so this is context, not proof of malicious intent.
EvidenceR0OmenCore_HardwareWorkerVirusTotal'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.
