The PDF contains numerous external links, characteristic of a link farm or SEO spam campaign, with one URL pointing to a potentially malicious domain. ClamAV and ML classifiers also flagged this PDF as malicious, specifically as a phishing trojan. While no scripts were extracted, the presence of embedded URLs and the heuristic firings strongly suggest a malicious intent to redirect users to harmful content.

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://bologen.ru/award?keyword=structure+of+bacterial+cell+wall+pdf
