The PDF contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic, pointing to various PDF files. One of these links, 'https://trafffe.ru/123?utm_term=bone+spicules+eye', is flagged as an external URI and is likely the primary malicious destination. The ClamAV detection and ML classifier strongly indicate malicious intent, consistent with phishing or SEO abuse.

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://trafffe.ru/123?utm_term=bone+spicules+eye
