T1059.007 JavaScript
The PDF contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic, pointing to various domains. The ClamAV detection and ML classifier strongly indicate malicious intent, specifically a phishing or trojan distribution. The embedded URLs are likely used to download second-stage payloads or redirect users to phishing sites.

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://lozipotod.ru/123?utm_term=rustoleum+cabinet+transformations+on+laminate
