MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of embedded URLs, identified as a link farm, suggesting a phishing or malware distribution campaign. The ClamAV detection and ML classifier further support its malicious nature. While no scripts were explicitly extracted, the structure and embedded URLs indicate an attempt to redirect users to potentially harmful content.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
