MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains multiple embedded URLs and a prominent call-to-action to download content, likely a malicious payload, related to game cheats and free currency. The ML classifier also flagged this PDF as malicious. The presence of embedded URLs and the lure suggest a phishing or social engineering attack aimed at tricking users into downloading malware.

  • Nyx PDF Classifier malicious score 0.8060

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.
