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

The PDF document was flagged by multiple heuristics, including ClamAV and an ML classifier, indicating malicious intent. The primary attack pattern observed is the embedding of a large number of external links, likely to distribute further malicious content or for SEO manipulation. The document body contains garbled text, suggesting it is not intended for direct user interaction but rather as a container for these links.

  • 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.
