Safe
Legitimate unsigned installer for OmenCore software matches AV-on-AV false positive shape with only low-trust heuristic detections.
ddbceea0f6a4244724…74b80be8bfThe reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
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.

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 rule matches
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.

Safety FAQ
Common questions about OmenCoreSetup-3.5.0.exe, answered from the scan data above.
- OmenCoreSetup-3.5.0.exe appears safe. 73 of 75 antivirus engines report it clean, with only 2 low-confidence detections that read as false positives. As a habit, only run files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
- OmenCoreSetup-3.5.0.exe is a Windows executable program, about 101.6 MB. Our analysis found no threat indicators for it. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
- 2 of 75 antivirus engines flagged OmenCoreSetup-3.5.0.exe, 2 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- The SHA-256 hash of OmenCoreSetup-3.5.0.exe is ddbceea0f6a4244724acac9dc1ee73126da0aada635b693056b27074b80be8bf, and its MD5 is 7bd3718cea2a55da8d9f0e35c84582ea. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- Based on this scan, yes — OmenCoreSetup-3.5.0.exe shows no threat indicators. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
- This report reflects the scan run on May 10, 2026. Because a file's hash never changes, the identity of OmenCoreSetup-3.5.0.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
