Is SIL Documentation SIL.pdf safe?
No engine among 75 flagged this PDF, including 17 tier-1 products, and available external intelligence produced no known threat match.
The PDF produced no malicious or suspicious detections across 75 engines, with 17 tier-1 products also reporting no detection. It is newly observed and lacks sandbox coverage, so ordinary caution remains appropriate despite the strong static results.

Before opening
Open it only when its sender or download source is one you independently trust.
If you already opened it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The PDF produced no malicious or suspicious detections across 75 engines, with 17 tier-1 products also reporting no detection. It is newly observed and lacks sandbox coverage, so ordinary caution remains appropriate despite the strong static results.
No antivirus engine among 75 identified the PDF as malicious or suspicious. All 17 reporting tier-1 engines, including Microsoft, Kaspersky, BitDefender, and ESET-NOD32, produced no detection. Research intelligence returned no MalwareBazaar, CIRCL, or YARAify match. Code signing is not meaningful for this PDF, so the lack of a signature is neutral. The main limitations are its first-day prevalence and the absence of completed runtime and contacted-host analysis.
What We Detected
None of 75 antivirus engines flagged the PDF, and all 17 reporting tier-1 engines produced no detection. MalwareBazaar, CIRCL, and YARAify also returned no match, with zero YARAify rules associated with the sample.
Threat Behavior
No completed sandbox observation is available, so runtime behavior cannot be characterized. No complete contacted-host reputation result is available either. The file is newly observed with one recorded submission, which limits reputation-based assurance.
What To Do Now
The available static evidence does not indicate malware. Open the document in an updated PDF reader with endpoint protection enabled, especially if it arrived unexpectedly or from an untrusted sender.
Where this verdict could be wrong3 caveats
- behaviour=null, so no sandbox execution was completed to check for embedded-script or exploit behavior.
- contactedHosts=null, so no complete host-reputation result is available.
- The file has only one recorded submission and was first observed today, leaving little reputation history.
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 MalwareBazaar, CIRCL, or YARAify match
- No brand mismatch was detected
- No heuristics were triggered
- First observed today with only one recorded submission
- No completed sandbox execution
- No complete contacted-host reputation result
The PDF can be handled with normal document precautions. Keep endpoint protection and the PDF reader enabled and fully updated, and verify the sender if the document was unsolicited.

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 its sender or download source is one you independently trust.
- 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.
