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

The PDF file contains a large number of external links to other PDF files hosted on various domains, as indicated by the PDF_SEO_LINK_FARM heuristic. The document body also contains embedded URLs, including one related to 'Bose quick connect terminal blocks', suggesting a lure to disguise the malicious nature of the links. The primary intent appears to be directing users to a link farm for SEO purposes, which can be a precursor to phishing or malware distribution.

Heuristics 3

  • 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.
  • 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.
