MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs and text fragments related to game hacks and free items, strongly suggesting a phishing or scam lure. The presence of an external URI pointing to a suspicious domain, combined with a high ML classifier score, indicates malicious intent. While no scripts were explicitly extracted, the document's structure and embedded URLs are designed to trick users into downloading further malicious content.

Heuristics 4

  • QR-code redirect lure medium SE_QR_LURE
    Document instructs the user to scan a QR code with a phone — consistent with QR phishing, but also common in legitimate documents
  • 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.
