MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains embedded URLs that lead to potentially malicious files, masquerading as game hacks or generators. The ML classifier strongly indicated maliciousness, and the presence of external URIs suggests an attempt to download a second-stage payload. The document body, though heavily obfuscated, contains references to game-related terms and URLs, reinforcing the lure.

Machine Learning

Heuristics 3

  • 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.
