MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document's content and embedded URLs promote free in-game currency and hacks, strongly suggesting a phishing or scam lure. The ML classifier also flagged this PDF as malicious. While no scripts were extracted, the presence of external URIs and the document's theme indicate a likely attempt to redirect users to malicious download sites.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
