The PDF file contains a large number of external links, many pointing to striking.ly domains, which is indicative of a link farm or SEO spamming technique. One of the primary external links, https://golowaki.ru/strik?utm_term=ejercicios+de+los+adjetivos+calificativos+en+ingles, is flagged as unknown reputation and is associated with a critical heuristic firing for PDF_SEO_LINK_FARM. ClamAV also detected this file as Pdf.Phishing.Trojan-d2528dad23a95d95-d2528dad23a95d95-10044376-0, strongly suggesting malicious intent.

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://golowaki.ru/strik?utm_term=ejercicios+de+los+adjetivos+calificativos+en+ingles PDF link annotation
