T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or SEO manipulation tactic. One of these links, https://traffine.ru/123?keyword=etna+maine+sheds, is flagged as suspicious. The ML classifier also strongly indicates maliciousness. While no scripts were explicitly extracted, the structure and heuristics point towards a malicious document designed to redirect users to potentially harmful content.

Heuristics 4
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall 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_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne 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.URL https://traffine.ru/123?keyword=etna+maine+sheds
