Is spoofer.drv.sys safe?
No engine detected malware in this unsigned driver-like executable, although its publisher is unverified and no completed runtime observation is available.
All 74 engines returned without a malicious or suspicious finding, including 16 tier-1 engines reporting clean. The file is unsigned and has one service-related static technique, while no completed sandbox run or complete host-reputation check is available, so ordinary caution remains appropriate.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 engines returned without a malicious or suspicious finding, including 16 tier-1 engines reporting clean. The file is unsigned and has one service-related static technique, while no completed sandbox run or complete host-reputation check is available, so ordinary caution remains appropriate.
The strongest evidence is the absence of malicious or suspicious findings across 74 engines, with no tier-1 detection or family consensus. Static PE analysis also found neither likely packing nor high-entropy code, and the external intelligence checks produced no known-malware or YARA matches. The file is unsigned, so its publisher and integrity cannot be authenticated through code signing. T1543.003 is listed as an offensive technique, but no completed sandbox run exists, so it cannot be described as runtime-observed activity. Host reputation was not checked or saved, although the available behavior record lists no no complete contacted-host reputation result was available file while leaving some uncertainty around provenance and execution behavior.
What We Detected
None of the 74 antivirus engines marked the sample malicious or suspicious. This includes 16 tier-1 engines reporting clean, with no malware-family consensus. Static PE analysis reports no likely packing and no high-entropy code, while CIRCL, MalwareBazaar, and YARAify supplied no corroborating threat hit.
Threat Behavior
The evidence lists T1543.003, a service-related technique that can be associated with driver or service installation. However, behaviour.sandboxCount=0 means no completed runtime observation is available, so this technique should be treated as static capability evidence rather than confirmed execution. The file is unsigned, and no signer history exists to establish its publisher. No complete contacted-host reputation result is available.
What To Do Now
Keep endpoint protection enabled and obtain the file from its official source whenever possible. Before installing a kernel-level component, verify its expected hash or publisher documentation and consider testing it in an isolated environment.
Where this verdict could be wrong3 caveats
- signing.signed=false leaves the publisher and integrity of this driver-like executable unverified.
- T1543.003 appears in behaviour.offensiveTechniques, but behaviour.sandboxCount=0 means there is no completed runtime observation to corroborate it.
- contactedHosts=null, so no completed host-reputation cross-check is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 engines reported malicious or suspicious findings.
- 16 tier-1 engines reported clean and tier1Malicious=0.
- No tier-1 malware-family consensus exists.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false.
- YARAify, CIRCL, and MalwareBazaar returned no threat hits.
- The executable is unsigned.
- No historical signer reputation is available.
- Static evidence includes T1543.003.
- No completed sandbox observation is available.
- No completed contacted-host reputation cross-check is available.
Use the file only if it came from a trusted official source and its hash matches the publisher's release information. Keep security protection enabled, especially because the executable is unsigned and driver-like.
