Is eoa (49).html safe?
No engine detected this HTML file, including 17 tier-1 products, though its embedded JavaScript remains unobserved at runtime and the sample is newly seen.
All 75 antivirus engines returned no malicious or suspicious detection, including 17 tier-1 products. This strongly favors benign content, but the HTML contains embedded JavaScript, has almost no reputation history, and lacks completed runtime or contacted-host analysis, so it should still come from a source you recognize.

If you already opened 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 detection, including 17 tier-1 products. This strongly favors benign content, but the HTML contains embedded JavaScript, has almost no reputation history, and lacks completed runtime or contacted-host analysis, so it should still come from a source you recognize.
The strongest evidence is that 0 of 75 engines flagged the sample, with all 17 reporting tier-1 engines returning no detection. No named malware family, suspicious heuristic, malicious child, or external-intelligence hit corroborates harmful content. The file is HTML with embedded JavaScript, but that tag alone does not establish malicious behavior. No sandbox run completed, so the script's runtime actions were not observed, and no complete host-reputation result is available. Because the sample is newly observed and YARAify timed out, confidence is lower than it would be for a well-established file with full dynamic coverage.
What We Detected
None of the 75 antivirus engines flagged the file as malicious or suspicious. The reporting set included 17 tier-1 engines, such as Microsoft, Kaspersky, ESET-NOD32, and BitDefender, all without detections. No malware-family label, triggered heuristic, or corroborating external-intelligence hit was present.
Threat Behavior
The file is a 17,216-byte HTML document tagged as containing embedded JavaScript. No completed sandbox observation is available, so the script's actual browser behavior was not observed. Contacted-host reputation was not checked or saved, and YARAify timed out, leaving those areas without complete coverage.
What To Do Now
Open the file only if its source and purpose are expected. Keep browser and endpoint protection enabled; if the file arrived unexpectedly or asks for credentials, downloads, or unusual permissions, do not interact with it and rescan after definitions update.
Where this verdict could be wrong3 caveats
- file.tags includes contains-embedded-js, and active HTML content can execute browser-side code even when static scanners report no detection.
- externalIntel.availability.yaraify=error means researcher-rule coverage was incomplete.
- prevalence.classification=rare_new provides little historical reputation despite the 0/75 detection result.
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 engines reported malicious or suspicious content.
- All 17 reporting tier-1 engines returned no detection.
- No malicious family consensus or hacktool label.
- No external-intelligence hit from the completed sources.
- No brand mismatch or adversarial-text contamination detected.
- HTML contains embedded JavaScript.
- First observed today with only one source and one submission.
- No completed sandbox runtime observation.
- No complete contacted-host reputation result.
- YARAify researcher-rule lookup timed out.
Use the file only when it came from a trusted, expected source, and keep browser and endpoint protection enabled. Avoid entering credentials or approving downloads if the page behaves unexpectedly.

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.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open it only when you trust its source; use an isolated viewer if the origin is uncertain.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
