MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a call-to-action lure, suggesting it is designed to trick users into downloading software. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple URLs pointing to game-related downloads indicates a likely attempt to distribute potentially unwanted or malicious applications. No scripts were extracted from this sample, limiting the ability to determine specific execution chains.

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.
