The PDF contains a large number of external links, many of which point to other PDF files, suggesting a link farm designed to manipulate search engine rankings or to host a variety of lures. One of the primary external links, https://jacksth.ru/strik?utm_term=naruto+ultimate+ninja+storm+apk, is suspicious and likely leads to a malicious payload. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution.

Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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://jacksth.ru/strik?utm_term=naruto+ultimate+ninja+storm+apk
