The PDF file contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic. One of the primary external links points to 'traffine.ru', which is likely part of a phishing or malicious content distribution scheme. The ClamAV detection and ML classifier also indicate malicious intent, classifying it as a phishing trojan.

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?utm_term=nicktoons+attack+of+the+toybots+ds
