Verdict Safe
Is Photovoltaique
Unsigned DLL with zero detections across 74 engines and mixed but mostly clean import-table fingerprint history.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
The file can be considered safe for normal use; continue monitoring only if it is executed from untrusted locations.

Why we think so
1 point against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
No engine flagged the file.
Zero detections from 74 engines including 17 major antivirus engines rules out any named malware family. The file is unsigned, which is common for internal or research DLLs. Two of three samples built with the same import table were previously marked safe. The single sandbox run showed only techniques common in legitimate software and no malicious verdict. The direct-IP rule is explicitly low-severity and cannot be confirmed malicious without host reputation data.
What We Detected
74 engines scanned the 12.5 MB Win32 DLL; none returned a malicious or suspicious result. The file is unsigned and carries no code-signing certificate. Sandbox execution recorded nine MITRE techniques common in legitimate software and one external IP contact (162.159.36.2) but produced no malicious verdict and no files it created.
Threat Behavior
No offensive techniques, persistence indicators, or registry modifications were observed. Host reputation for the IP is unavailable because contactedHosts was not populated.
What To Do Now
Keep existing security software enabled. If the DLL is required for a specific application, restrict its execution to a controlled environment and monitor for unexpected outbound connections until its legitimacy is confirmed by the software vendor.
Where this verdict could be wrong1 caveat
- similarHashes[0] returned malicious (Zusy) on import-table fingerprint match without signer correlation — framework collision possible.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero detections across 74 engines
- No malicious sandbox verdict
