The PDF file was detected as malicious by ClamAV and an ML classifier, indicating a phishing or trojan threat. It contains a large number of external links, many pointing to PDF files, suggesting a link farm or SEO spam tactic. The primary URL, 'https://trafffe.ru/strik?keyword=teresa+fidalgo+the+real+story', is likely used to redirect users to malicious content or phishing pages.

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://trafffe.ru/strik?keyword=teresa+fidalgo+the+real+story
