MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links to other PDF files hosted on various domains, as indicated by the PDF_SEO_LINK_FARM heuristic. The document body text, though partially corrupted, includes a URL that points to one of these external PDFs. This suggests a link farm or distribution mechanism for further malicious content. No scripts were extracted from this sample.

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.
