The PDF contains a large number of external links, many pointing to PDF files, suggesting a link farm or phishing attempt. The primary URL, 'https://kuzutuzo.ru/123?utm_term=dorset+police+report+a+crime+online', is presented as a way to report a crime, which is a common social engineering tactic. ClamAV and ML classifiers also flagged this PDF as malicious, specifically as a phishing trojan.

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/123?utm_term=dorset+police+report+a+crime+online
