T1059.007 JavaScript
The PDF contains a large number of external links, many of which are likely part of a link farm designed to manipulate search engine results or direct users to malicious sites. The ClamAV detection and ML classifier strongly indicate malicious intent, specifically identified as a phishing or trojan. While no scripts were explicitly extracted, the PDF structure and numerous external links suggest an attempt to redirect users to potentially 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://cructi.ru/pbw?utm_term=dna+structure+and+replication+answer+key
