This PDF file was flagged by multiple heuristics as malicious, including ClamAV detection and an ML classifier. It contains a large number of external links, many pointing to PDF files, suggesting a link farm or phishing attempt. One of the embedded URLs, 'https://pelibifir.ru/wix?keyword=gotranscript+quiz+answers+january+2020', is likely part of a lure to direct users to a malicious site.

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://pelibifir.ru/wix?keyword=gotranscript+quiz+answers+january+2020
