The PDF contains numerous external links, with a critical heuristic firing for a 'PDF_SEO_LINK_FARM'. One of the primary external links, 'https://resalured.ru/wix?keyword=proceso+de+ovogenesis+y+espermatogenesis+pdf', suggests a lure related to biological processes to attract traffic. The presence of embedded URLs and the ML classifier's high confidence score further support a malicious classification, likely for phishing or malware distribution.

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://resalured.ru/wix?keyword=proceso+de+ovogenesis+y+espermatogenesis+pdf
