MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document body and embedded URLs promote free game-related items, a common lure for phishing or malware distribution. While no scripts were explicitly extracted, the presence of embedded URLs and the ML classification suggest the PDF is designed to redirect users to malicious sites or download further payloads.

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