MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly advertises a "Coin Master Hack Tool" and related game cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect the user to download potentially harmful content. No scripts were extracted, but the document's content and heuristics indicate a phishing or social engineering lure.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
