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

The PDF contains a significant number of embedded URLs pointing to other PDF files, a technique often used for SEO spam or to distribute further malicious content. The ML classifier also flagged this PDF as malicious. While no scripts were extracted, the sheer volume of links suggests a malicious intent to either drive traffic or host malicious payloads. The document body is heavily obfuscated and unreadable.

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.
