Is NexusRecoil.dll safe?
Only APEX flagged the file among 75 engines, while tier-1 engines remained silent and runtime evidence produced no corroborated malware finding.
APEX was the sole detector among 75 engines, and it is categorized as low trust; all 17 reporting tier-1 engines found nothing. One sandbox mapped activity to T1055 Process Injection, but issued no malicious verdict, found no persistence or dropped payloads, and contacted no host known to be harmful.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
APEX was the sole detector among 75 engines, and it is categorized as low trust; all 17 reporting tier-1 engines found nothing. One sandbox mapped activity to T1055 Process Injection, but issued no malicious verdict, found no persistence or dropped payloads, and contacted no host known to be harmful.
The detection pattern is dominated by a single generic APEX result, with no support from any tier-1 or tier-2 engine. Runtime analysis completed and mapped possible process injection to T1055, so the sample is not entirely risk-free. However, that run did not produce a malicious sandbox verdict, persistence indicators, dropped payload hashes, or corroborating threat intelligence. Reputation checks covered all 15 distinct contacted domains and found no known-malicious or suspicious host. The unsigned status prevents publisher verification, but the combined evidence makes the lone detection substantially more likely to be a false positive than a confirmed threat.
What We Detected
Only APEX flagged the sample among 75 antivirus engines, using the generic label “Malicious.” APEX is marked low trust here, while all 17 reporting tier-1 engines—including Avast, BitDefender, ESET, Kaspersky, and Fortinet—reported no detection. CIRCL, MalwareBazaar, and YARAify supplied no corroborating hit.
Threat Behavior
One completed sandbox run mapped activity to MITRE T1055 Process Injection, which is a meaningful risk indicator but does not by itself establish harmful intent. The sandbox issued no malicious verdict and recorded no persistence indicators, registry modifications, or dropped payload hashes. Reputation coverage inspected all 15 distinct contacted domains and found no known-malicious or suspicious hosts. The executable is unsigned, so its publisher cannot be authenticated.
What To Do Now
Keep endpoint protection enabled and obtain the file from its official distribution channel when possible. If its origin is uncertain or the observed injection behavior is unexpected, test it in an isolated environment and request publisher verification before deploying it broadly.
Where this verdict could be wrong2 caveats
- The file is unsigned despite signing.applicable=true, so there is no verified publisher identity or signer history.
- The saved runtime evidence maps activity to MITRE T1055 Process Injection, an offensive technique that warrants caution even though the sandbox did not issue a malicious verdict.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- All 17 reporting tier-1 engines were clean
- Only 1/75 engines flagged the sample, and that detector is low trust
- The completed sandbox produced no malicious verdict
- All 15 distinct contacted domains received complete reputation coverage with no harmful matches
- No external-intelligence hits, persistence indicators, or dropped payload hashes were found
- Unsigned executable with no verified publisher or signer history
- Runtime evidence mapped activity to MITRE T1055 Process Injection
- APEX produced one generic malicious detection
Keep protection enabled and use the file only if it came from a trusted, verifiable source. For sensitive systems, confirm the expected T1055-related behavior with the developer before deployment.

The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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.
