MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains embedded URLs and text that mimic lures for free in-game items, such as Robux and Minecraft accounts. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect users to malicious sites. No scripts were extracted, but the overall pattern indicates a phishing or malware distribution attempt.

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.
