This PDF file exhibits characteristics of a phishing or malware distribution lure, as indicated by the ML classifier and ClamAV detection. It contains a large number of external links, many pointing to S3 buckets and other file-sharing services, which are likely part of a link farm designed to improve search engine rankings for malicious content. The primary malicious URL identified is https://maypoin.ru/strik, which is likely used to redirect users to a malicious payload or phishing site.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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://maypoin.ru/strik?utm_term=download+nexus+for+fl+studio+12+free PDF link annotation
