The PDF file contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. One of these links, 'https://traffnew.ru/123?utm_term=rosemarie+putnam+tong+feminist+thought', is directly associated with the malicious verdict. The presence of numerous links suggests an attempt to direct users to potentially malicious or spam-related websites, aligning with phishing or SEO manipulation tactics. No scripts were extracted, but the structure and heuristics point towards a malicious PDF.

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.
