MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains multiple URLs pointing to sites offering game-related cheats and hacks, suggesting a lure for users seeking in-game advantages. The presence of a download button lure and callback phishing indicators further supports a malicious intent, likely to trick users into downloading malware or falling for a scam. Although no scripts were explicitly extracted, the PDF structure and embedded URLs are indicative of a phishing or scam attempt.

  • Nyx PDF Classifier malicious score 0.9980

Heuristics 4

  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
  • 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.
