MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF contains an embedded URI pointing to a suspicious domain, and a machine learning classifier flagged it as malicious. The document body, though heavily garbled, contains references to 'Robux' and a URL that suggests a lure for game-related cheats or hacks. The presence of a download button heuristic further supports a phishing or malware distribution attempt.

Machine Learning

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
