T1566.001 Spearphishing Attachment

The PDF contains numerous embedded links, many of which point to compromised websites or disposable hosting, indicating a link farm designed to redirect users to malicious content. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the structure and heuristics suggest the document's primary purpose is to facilitate the download or redirection to a secondary malicious payload.

Heuristics 4

  • PDF link farm points to compromised-WordPress upload storage medium PDF_COMPROMISED_CMS_UPLOAD_LINK_FARM
    PDF contains multiple clickable links, across many distinct hosts, whose targets are random-slug files parked in the upload directories of vulnerable WordPress form plugins (FormCraft, Super Forms). This is the hallmark of the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains hosted on compromised sites. The PDF itself carries no exploit — the risk is the linked destinations.
  • Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARM
    Small PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.

    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
