Safe
Legitimate unsigned installer for OmenCore software matches AV-on-AV false positive shape with only low-trust heuristic detections.
ddbceea0f6a4244724…74b80be8bfThe verdict, reasoned out.
Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.
The file triggers the exact AV-on-AV false positive pattern: security-software-like filename, exactly 2 low-trust heuristic detections, and zero tier1 malicious hits. Behavioral signals like process injection (T1055) and direct IP contact are concerning but align with installer actions (e.g., GitHub API check) and lack sandbox confirmation. Clean dropped children, no malicious hosts, and medium prevalence for a 2-day-old file support safety. Heuristics alone do not override the strong FP indicators.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

- Direct IP contact (140.82.114.6) without DNS
- Persistence indicator ('R0OmenCore_HardwareWorker')
This appears safe as a legitimate OmenCore installer falsely flagged by heuristics. Run only if sourced from the official GitHub repository (theantipopau/omencore); otherwise, delete and source from vendor.

YARA + heuristic rules that fired
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
Sandbox flagged persistence indicators (registry Run keys / services / scheduled tasks).
EvidenceR0OmenCore_HardwareWorkerMITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
EvidenceC:\Windows\System32\svchost.exe -k smphostSample contacted 1 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.
