MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains numerous links to websites offering game cheats and hacks, including a prominent link to 'coin-master-free-gold-cards-link-2021ee-spins-game-hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a download button lure suggests an attempt to trick the user into downloading potentially harmful content or visiting a phishing site. No scripts were extracted, but the overall pattern indicates a social engineering lure for malicious downloads.

Machine Learning

  • 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.
