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

The PDF file contains a large number of embedded external links, a technique often used for SEO manipulation or to distribute further malicious content. The heuristic 'PDF_SEO_LINK_FARM' specifically flags this behavior, indicating a mass of external PDF links. The document body is heavily obfuscated, but the presence of URLs suggests a delivery mechanism for potentially harmful content hosted on external domains.

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.
