MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, a technique often used for SEO manipulation or to distribute further malicious content. The heuristic 'PDF_SEO_LINK_FARM' specifically identifies this behavior, pointing to numerous URLs hosted on domains like jazcustoms.com and host202.carmichaelnl.com. While no scripts were extracted, the sheer volume of outbound links suggests a malicious intent to redirect the user to potentially harmful websites.

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.

Embedded URL info EMBEDDED_URL
