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 file is a non-executable Markdown document, and 0 of 75 antivirus engines detected a threat, including all 17 reporting tier-1 engines. It is newly observed and has no sandbox results, but the available static evidence contains no indication of malware.
The sample is identified as a text/Markdown document rather than executable code. None of 75 antivirus engines flagged it, and 17 tier-1 engines reported no detection. Research intelligence produced no YARA, known-malware repository, or reference-database match. Because no sandbox run completed, runtime behavior cannot be characterized, and no complete contacted-host reputation result is available. The file is newly observed, but that limited history is not accompanied by any concrete threat signal.
What We Detected
The sample is a 193,884-byte Markdown text file. No antivirus engine among 75 flagged it as malicious or suspicious, and all 17 reporting tier-1 engines returned no detection. Research intelligence also found no YARA rule match or known-malware repository entry.
Threat Behavior
No completed sandbox observation is available, so runtime behavior was not assessed. No complete contacted-host reputation result is available either. As a Markdown document, the file is not itself a native executable, although links or embedded content should still be treated cautiously when opened by supporting applications.
What To Do Now
The available static evidence supports normal handling. Keep endpoint protection enabled, open the document with an updated Markdown viewer or text editor, and avoid following unexpected links or executing copied commands without reviewing them.
Where this verdict could be wrong2 caveats
- prevalence.classification=rare_new with 1 submitter and 1 submission means there is little history for this exact hash.
- behaviour=null and contactedHosts=null leave runtime activity and contacted-host reputation unassessed.
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
- file.mimeType=text/markdown indicates non-executable text
- externalIntel.yaraify.ruleCount=0
- externalIntel.malwareBazaar.hit=false
- prevalence.classification=rare_new: only 1 submitter and 1 submission
- behaviour=null: no completed runtime observation
- contactedHosts=null: no complete host-reputation cross-check
The document can be handled normally with an updated text or Markdown viewer. Keep endpoint protection enabled and review any embedded links or commands before interacting with them.

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.

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.
