The PDF file contains a heuristic firing for PDF_SEO_LINK_FARM, indicating it's part of a link farm designed to generate traffic or distribute malicious content. The embedded URL 'https://trafffi.ru/aws?utm_term=jurnal+gametogenesis+pdf' suggests a phishing or content-luring attempt. ClamAV detection as 'Pdf.Phishing.Trojan' further supports its malicious nature.

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://trafffi.ru/aws?utm_term=jurnal+gametogenesis+pdf
