Is CET IR35 - New Supplier IR35 Information Sheet (revised 30.9.25).docx safe?
No antivirus engine detected a threat in this DOCX, though its very recent appearance and lack of runtime observation warrant ordinary document precautions.
All 75 antivirus engines returned without a malicious or suspicious finding, including 17 tier-1 engines. No curated threat-intelligence match was present, but the file is newly observed and has not undergone completed runtime analysis, so open it only if the sender and business context are expected.

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.

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 without a malicious or suspicious finding, including 17 tier-1 engines. No curated threat-intelligence match was present, but the file is newly observed and has not undergone completed runtime analysis, so open it only if the sender and business context are expected.
The document received zero malicious and zero suspicious findings across 75 antivirus engines. All 17 tier-1 engines were silent, and no family consensus or offensive-tool label appeared. MalwareBazaar, YARAify, and CIRCL supplied no corroborating threat match. The main limitations are that the sample is rare and newly observed, with no completed runtime observation or host-reputation cross-check. Prior file-type matches mostly had clean outcomes, but those matches are weak because they share only the DOCX format.
What We Detected
None of 75 antivirus engines flagged the DOCX as malicious or suspicious. The results include 17 tier-1 engines, with BitDefender, ESET-NOD32, Kaspersky, and Microsoft among those reporting no detection. MalwareBazaar, YARAify, and CIRCL supplied no matching threat intelligence.
Threat Behavior
No completed sandbox run is available, so runtime behavior was not observed. No complete contacted-host reputation result is available either. The document is newly observed from only two sources, which limits reputation-based confidence, while the prior similar records are based only on file type and therefore provide weak support.
What To Do Now
Confirm that the sender and IR35 supplier context are expected before opening the document. Keep endpoint protection and Microsoft Office security features enabled, and avoid enabling active content if the application unexpectedly requests it.
Where this verdict could be wrong4 caveats
- prevalence.classification=rare_new and file.ageDays=0 provide little reputation history despite the absence of detections.
- behaviour=null means no completed runtime observation is available to confirm how the document behaves when opened.
- contactedHosts=null means no complete host-reputation result is available.
- The four prior 'safe' entries in similarHashes use matchKind=filetype, which is weak similarity and does not establish shared content.
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 finding
- tier1Malicious=0 and tier1ReportedClean=17
- externalIntel.malwareBazaar.hit=false
- externalIntel.yaraify.ruleCount=0
- No brand mismatch or adversarial-input flag was detected
- Newly observed sample with file.ageDays=0
- Low prevalence: prevalence.uniqueSources=2
- No completed runtime observation because behaviour=null
- No complete contacted-host reputation result because contactedHosts=null
Open the document only when its sender and business purpose are expected. Keep antivirus and Office protections enabled, and do not enable unexpected active content.

Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.

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.
