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

The PDF contains a large number of external links to various domains, a technique often used for SEO poisoning or link farming. The heuristic 'PDF_SEO_LINK_FARM' specifically flags this behavior, indicating a likely attempt to redirect users to potentially malicious content. The embedded URL 'http://aqueenwithpurposeshop.com/uploads/1/3/0/2/130289675/130289675.html#haz+llover+haz+llover+abre+las+puertas' is also part of this network. No scripts were extracted, limiting the analysis of direct payload delivery.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
