Is ZenithFanUtility_v1.0.0.zip safe?
None of 76 engines detected malware, while one sandbox produced concerning technique mappings without a malicious conclusion or confirmed harmful child.
The archive received no malicious or suspicious detections from 76 engines, including no tier-1 flags. One sandbox mapped activity to several offensive MITRE techniques, but issued no malicious conclusion, observed no network contacts, and yielded no confirmed harmful child.

Before opening or extracting
Open or extract it only when its sender or download source has been independently verified.
If you already opened or extracted 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.
The archive received no malicious or suspicious detections from 76 engines, including no tier-1 flags. One sandbox mapped activity to several offensive MITRE techniques, but issued no malicious conclusion, observed no network contacts, and yielded no confirmed harmful child.
Static scanning produced 0 detections across 76 engines, with all 17 reporting tier-1 engines finding no threat. One completed sandbox run mapped activity to T1055, T1485, T1486, and T1562.001, making the runtime evidence worth noting. The process-injection heuristic derives from rundll32 loading AsusWinIO64.dll and does not, by itself, establish malicious intent for a hardware-control utility. The sandbox recorded no malicious conclusion or network contacts, and none of 10 inspected children was confirmed harmful, although their individual verdicts remain unknown. Research intelligence supplied no family match or corroborating rules, and no complete contacted-host reputation result is available.
What We Detected
None of 76 antivirus engines flagged the ZIP archive, including all 17 reporting tier-1 engines. Research intelligence also returned no family match, reference hit, or matching YARA rule.
Threat Behavior
One completed sandbox run mapped activity to T1055, T1485, T1486, and T1562.001. In particular, rundll32 loaded AsusWinIO64.dll, which triggered a possible process-injection heuristic; low-level driver or hardware-control behavior can resemble offensive activity, so this remains a caution signal rather than proof. The run produced no malicious sandbox conclusion and recorded no contacted domains, IP addresses, or URLs. Ten children were inspected without a confirmed harmful result, though all ten remain individually unclassified, and no complete contacted-host reputation cross-check is available.
What To Do Now
Use the archive only if it came from the utility's official release channel, and keep endpoint protection enabled. If its origin cannot be verified, inspect the extracted executables and DLLs individually before running them with administrator privileges.
Where this verdict could be wrong3 caveats
- The T1055, T1485, T1486, and T1562.001 runtime mappings are meaningful counter-signals, although the sole sandbox did not issue a malicious verdict.
- All 10 inspected children have unknown rather than safe verdicts, so droppedChildren.hasMaliciousChild=false is limited evidence.
- contactedHosts=null, meaning no complete host-reputation cross-check is available; however, the sandbox recorded no contacted domains, IPs, or URLs.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/76 engines reported a malicious or suspicious result.
- All 17 reporting tier-1 engines returned no detection.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false across 10 inspected children.
- YARAify, CIRCL, and MalwareBazaar supplied no corroborating hit.
- One sandbox mapped runtime activity to offensive techniques T1055, T1485, T1486, and T1562.001.
- MalwareTips.Synth.ProcessInjection fired when rundll32.exe loaded AsusWinIO64.dll.
- The archive carries detect-debug-environment and long-sleeps tags.
- All 10 extracted children remain individually unclassified.
- No complete contacted-host reputation cross-check is available.
Obtain the archive from the utility's official release channel and keep endpoint protection enabled. If provenance is uncertain, avoid administrator execution until the extracted components are separately verified.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
