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

The PDF file exhibits a 'PDF_SEO_LINK_FARM' heuristic, indicating a large number of embedded external links. The document body is heavily obfuscated and unreadable, but the presence of numerous links to various PDF files suggests an attempt to manipulate search engine rankings or distribute further malicious content. The primary attack pattern involves leveraging these links for malicious purposes.

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.
