T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a significant number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic. The primary URL, 'https://kuzutuzo.ru/strik?utm_term=materia+y+energia+en+el+ecosistema', suggests a phishing or malicious redirection attempt. ClamAV also detected this file as 'Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0', reinforcing the malicious classification. While no scripts were explicitly extracted, the nature of the link farm and the ClamAV detection strongly indicate a malicious intent to redirect users to potentially harmful content.

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://kuzutuzo.ru/strik?utm_term=materia+y+energia+en+el+ecosistema PDF link annotation
