The PDF file contains numerous external links, with a significant heuristic firing indicating a link farm designed to direct users to various PDF documents. One of the primary external URIs, 'https://dafemum.ru/strik?utm_term=cuanto+equivale+un+metro+cuadrado+en+pulgadas', is flagged as suspicious. The ML classifier and ClamAV detection strongly indicate malicious intent, likely for phishing or distributing further malware.

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://dafemum.ru/strik?utm_term=cuanto+equivale+un+metro+cuadrado+en+pulgadas
