MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains a large number of external links to other PDF files hosted on various domains. This technique is often used for SEO poisoning or to distribute malicious content indirectly. No scripts were extracted, and the document body is largely unreadable, but the heuristic firings strongly indicate a link farm intended to direct users to external resources. The primary IOCs are the numerous URLs embedded within the document.

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.
