Is 0917Invoice sheet_5347.zip safe?
Two tier-1 engines flagged this invoice-themed ZIP generically, but broad engine disagreement and absent runtime evidence prevent reliable family attribution.
Avira and F-Secure flagged the archive with generic W64 malware labels, creating meaningful concern despite only 3 of 74 engines detecting it. Thirteen tier-1 engines reported no detection, and no runtime analysis or complete host-reputation check is available, so the evidence remains mixed.

Before opening or extracting
Do not open or extract it until the source can be verified independently.
If you already opened or extracted it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the original trusted source and verify its exact hash when possible.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Avira and F-Secure flagged the archive with generic W64 malware labels, creating meaningful concern despite only 3 of 74 engines detecting it. Thirteen tier-1 engines reported no detection, and no runtime analysis or complete host-reputation check is available, so the evidence remains mixed.
Three of 74 engines flagged the archive, with Avira and F-Secure supplying two independent tier-1 detections. Their labels are generic W64 malware designations, and no tier-1 family consensus identifies a specific threat. Thirteen other tier-1 engines reported no detection, which makes a false positive plausible but does not neutralize two high-trust warnings. No completed runtime observation is available, and contacted-host reputation was not checked or saved. External researcher intelligence produced no hits, while the filetype-only similarity records are mixed and too weak to settle the conflict.
What We Detected
Three of 74 antivirus engines flagged the ZIP archive. Avira reported “TR/W64.Malware,” F-Secure reported “Trojan.TR/W64.Malware,” and Cynet supplied a generic malicious score. The first two are tier-1 detections, but no named malware family achieved consensus.
Threat Behavior
No completed sandbox observation is available, so execution behavior, persistence, payload extraction, and network activity were not observed. The contacted-host reputation cross-check was also not completed or saved, meaning no complete network-reputation conclusion can be made. No malicious dropped child was established.
What To Do Now
Do not open or extract the archive unless the invoice was expected and independently confirmed with the sender through a trusted channel. Keep endpoint protection enabled, quarantine the file, and inspect extracted contents in an isolated analysis environment if business use requires further review.
Where this verdict could be wrong3 caveats
- Only 3/74 engines detected the archive, while 13 tier-1 engines reported no detection.
- externalIntel.yaraify.ruleCount=0, externalIntel.circl.hit=false, and externalIntel.malwareBazaar.hit=false provide no independent malicious corroboration, although coverage gaps remain possible.
- Three of five filetype-only similarHashes entries received prior safe verdicts, but file-type similarity alone is weak.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 3/74 engines reported a detection
- 13 tier-1 engines reported no detection
- No tier-1 malware-family consensus
- YARAify returned 0 matching rules
- CIRCL and MalwareBazaar returned no hits
- Two tier-1 detections from Avira and F-Secure
- Invoice-themed ZIP archive may be used for social engineering
- Generic W64 malware labels without family attribution
- No completed runtime analysis
- No complete contacted-host reputation result
Quarantine the archive and verify the supposed invoice with the sender before opening it. Keep endpoint protection enabled and use an isolated analysis environment for any necessary extraction.
