The PDF contains a heuristic firing for PDF_SEO_LINK_FARM, indicating it's part of a link farm designed to boost search engine rankings. It embeds multiple external links, one of which, 'https://fokemale.ru/strik?utm_term=razones+trigonometricas+de+angulos+suplementarios+ejercicios+resueltos+pdf', is flagged as suspicious. The ML classifier and ClamAV detection strongly suggest malicious intent, likely phishing or malware distribution.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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://fokemale.ru/strik?utm_term=razones+trigonometricas+de+angulos+suplementarios+ejercicios+resueltos+pdf PDF link annotation
