MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that explicitly advertises hacks and free in-game currency for popular games like Roblox and Coin Master. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to download malicious content. While no scripts were explicitly extracted, the overall structure and content point to a phishing or malware distribution lure.

  • 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.
