T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a large number of external links, as indicated by the PDF_SEO_LINK_FARM heuristic. The primary URL, https://vilenefex.ru/strik?utm_term=folk+music+english+means, suggests a potential phishing or malicious content delivery attempt. While no scripts were explicitly extracted, the presence of numerous external links and the ClamAV detection as Pdf.Phishing.Trojan strongly indicate a malicious intent to redirect users to harmful sites.

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://vilenefex.ru/strik?utm_term=folk+music+english+means
