MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF was flagged by a critical heuristic for containing a large number of external links, suggesting a link farm or a phishing attempt. The ML classifier also indicated a high probability of maliciousness. While no scripts were extracted, the sheer volume of embedded URLs points towards an attempt to lure users to potentially malicious external sites, likely as part of a phishing or content-scraping scheme.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
