T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains numerous embedded links, including a primary URL pointing to a "Roblox Super Power Training Simulator Token Hack". The document's structure and content strongly suggest a phishing or malware distribution attempt, masquerading as a game cheat. The ML classifier and the presence of a link farm further support its malicious nature.

  • 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.
