Is pdf-seeds.html safe?
No engine detected a threat in this HTML file, although its embedded JavaScript remains unobserved at runtime and the sample is newly seen.
All 75 antivirus engines produced no malicious or suspicious detection, including 17 tier-1 engines. The file is newly observed and contains embedded JavaScript, while no sandbox run or complete contacted-host check is available, so it should still be opened only if its source and purpose are expected.

Before opening
Open it only when you trust its source; use an isolated viewer if the origin is uncertain.
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 produced no malicious or suspicious detection, including 17 tier-1 engines. The file is newly observed and contains embedded JavaScript, while no sandbox run or complete contacted-host check is available, so it should still be opened only if its source and purpose are expected.
Static scanning found no malicious or suspicious result among 75 engines, and all 17 participating tier-1 engines were silent. External intelligence produced no known-malware, reference-database, or researcher-rule match. The sample is newly observed with only one recorded submission, which limits reputation-based assurance. Its HTML includes embedded JavaScript, but no completed sandbox observation exists to establish what that code does at runtime. Similar-file history is inconclusive because the three matches share only the broad HTML file type.
What We Detected
The 21,460-byte HTML file contains embedded JavaScript, but 0 of 75 antivirus engines reported it as malicious or suspicious. All 17 tier-1 engines that contributed results produced no detection, and no external malware or researcher-rule match was found.
Threat Behavior
No completed sandbox run is available, so the JavaScript's runtime actions were not observed. Contacted-host reputation was also not checked or saved, meaning no complete network-reputation conclusion can be drawn. The file is newly observed and has only one recorded submission.
What To Do Now
Open the file only if it came from an expected source and its purpose is understood. Keep browser and endpoint protection enabled; if the origin is uncertain, inspect it in an isolated environment or obtain a fresh copy from the expected sender.
Where this verdict could be wrong3 caveats
- The file was first submitted today and has only one recorded submission, so its 0/75 detection result has not yet accumulated a long reputation history.
- behaviour=null and contactedHosts=null mean neither runtime activity nor complete contacted-host reputation was evaluated.
- The 'contains-embedded-js' tag indicates active content that static engines may not fully assess.
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 a malicious or suspicious result
- 17 tier-1 engines reported no detection
- No YARAify, MalwareBazaar, or CIRCL hit
- No brand mismatch or adversarial-input indication
- Newly observed sample with only one recorded submission
- Embedded JavaScript can execute active browser-side content
- No completed runtime observation
- No complete contacted-host reputation result
Use the file if it came from a trusted, expected source; otherwise inspect it in isolation before opening. Keep browser and endpoint protection enabled.

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.
