T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a mass of external links, many pointing to PDFs, suggesting a link farm or SEO manipulation tactic. The primary URL, https://vilenefex.ru/strik?utm_term=the+bodybuilder%2527s+nutrition+book+pdf+free+download, is likely part of a phishing or scam operation disguised as a free download. While no scripts were explicitly extracted, the PDF structure and heuristic firings indicate malicious intent, possibly involving embedded JavaScript for exploitation or redirection.

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=the+bodybuilder%2527s+nutrition+book+pdf+free+download
