MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URI pointing to a URL that promises free in-game currency for Coin Master, a common lure for phishing and scam sites. The ML classifier also flagged the PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure suggest an attempt to direct users to a malicious external resource.

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
