MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, suggesting a link farm or SEO poisoning attempt. The document body, though heavily obfuscated, contains one of these URLs, indicating the primary intent is to redirect the user. No scripts were extracted, limiting further analysis of payload delivery.

Heuristics 3

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

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.
