MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of external links, characteristic of a link farm designed to distribute malicious content. The document body, though partially obfuscated, includes a URL that points to an HTML file, which likely serves as a landing page to redirect users to further malicious PDFs. The presence of numerous similar URLs across different domains reinforces the link farm pattern.

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.
