MITRE ATT&CK

T1566.001 Spearphishing Attachment

The primary attack pattern involves directing users to click these links, which could be for SEO manipulation or to distribute further malicious content. No scripts were extracted from this sample.

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.
