Is NixThis.exe safe?
No antivirus engine detected this executable, though its unsigned, recently observed status and process-injection-related sandbox mapping justify continued caution.
All 75 antivirus engines returned no malicious or suspicious result, including 17 tier-1 participants, and the completed sandbox run did not issue a malicious conclusion. However, the file is unsigned and recently observed, while runtime mappings include process injection and defense impairment, so it should only be run if its source and purpose are trusted.

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.
All 75 antivirus engines returned no malicious or suspicious result, including 17 tier-1 participants, and the completed sandbox run did not issue a malicious conclusion. However, the file is unsigned and recently observed, while runtime mappings include process injection and defense impairment, so it should only be run if its source and purpose are trusted.
The strongest evidence is the complete absence of detections across 75 antivirus engines, including all 17 participating tier-1 engines. One completed sandbox run produced no malicious conclusion and recorded no dropped payloads or persistence indicators. It nevertheless mapped activity to T1055 and T1562.001, which are meaningful risk signals but do not establish intent or a malware family by themselves. Confidence is reduced because this is an unsigned executable with only two submissions and probable packing. Independent intelligence sources supplied no corroborating family or rule match, while a complete contacted-host reputation check is unavailable.
What We Detected
None of 75 antivirus engines flagged the executable, and all 17 participating tier-1 engines reported no detection. No malware family was identified, no malicious child was recorded, and external intelligence returned no MalwareBazaar, CIRCL, or YARAify match.
Threat Behavior
One completed sandbox run did not issue a malicious conclusion, but it mapped activity to T1055 (Process Injection) and T1562.001 (Impair Defenses). These mappings warrant caution, although the saved evidence does not prove the exact injection method, defensive interference, or malicious intent. The run listed no contacted domains, IP addresses, or URLs; however, contactedHosts is unavailable, so no complete host-reputation result exists. The executable is unsigned, recently observed, and marked likelyPacked=true.
What To Do Now
Verify that the file came from the expected developer or an official distribution channel before running it. Keep endpoint protection enabled, and avoid executing it on an important system if its origin or purpose cannot be independently confirmed.
Where this verdict could be wrong3 caveats
- The T1055 and T1562.001 mappings suggest process injection and impairment of defenses, although the evidence does not establish the exact method or intent.
- The executable is unsigned, recently observed, and likelyPacked=true, reducing confidence despite the absence of antivirus detections.
- contactedHosts=null, so no complete reputation cross-check exists for runtime network destinations.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines reported a malicious or suspicious result
- All 17 participating tier-1 engines reported no detection
- One completed sandbox run had no malicious verdict
- No dropped malicious child or persistence indicator was recorded
- No MalwareBazaar, CIRCL, or YARAify hit
- Unsigned Win32 executable with no established signer history
- Only 2 submissions from 2 sources and first observed four days ago
- Runtime mapping to T1055 process injection
- Runtime mapping to T1562.001 impairment of defenses
- peAnalysis.likelyPacked=true
- No complete contacted-host reputation cross-check
Use the executable only if its origin and intended function can be verified independently. Keep endpoint protection enabled and consider testing it in an isolated environment first.

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.

Section entropy & packers
A known packer signature (UPX / Themida / VMProtect / etc.) matched this file. Packers aren't malicious on their own, but most malware uses them.
Packers compress or encrypt the executable and only unpack it at runtime. Legitimate commercial software uses them too — but if the file is also unsigned and rare, it's a strong malware signal.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.
