MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a visual lure suggesting a download or cheat site, strongly indicating a phishing or malware distribution attempt. The ML classifier's high confidence score further supports this assessment. Although no scripts were explicitly extracted, the presence of embedded URIs and the document's content suggest it is designed to redirect users to malicious sites.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
