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

The PDF document contains a large number of embedded external links, a technique often used for SEO spam or to redirect users to malicious sites. The heuristic 'PDF_SEO_LINK_FARM' specifically flags this behavior, indicating a mass of external links. The document body, while containing some seemingly benign text about an alphabet, also includes several of these suspicious URLs, reinforcing the malicious intent. No scripts were extracted, limiting the analysis to the link farm behavior.

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.
