The PDF contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various PDF files. The primary URL, https://soxebez.ru/strik, is likely part of a phishing or malware distribution campaign. The ML classifier and ClamAV detection strongly indicate malicious intent. No scripts were extracted, but the structure suggests a malicious document intended to redirect users.

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://soxebez.ru/strik?utm_term=what+do+density+currents+do
