T1059.007 JavaScript
The PDF file was flagged by multiple heuristics, including ClamAV and an ML classifier, indicating malicious content. It contains a large number of external links, many of which are likely part of a link farm designed to direct users to malicious sites, as suggested by the PDF_SEO_LINK_FARM heuristic. The embedded URL `https://traffine.ru/strik?utm_term=blackfoot+mental+institution` is a primary indicator of malicious intent, likely serving as a redirector or landing page for further attacks.

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/strik?utm_term=blackfoot+mental+institution
