T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous embedded URLs, many of which are part of a link farm, indicating a malicious intent to redirect users to external sites. The ClamAV detection and ML classifier strongly suggest this PDF is a phishing or malware distribution tool. The presence of embedded URLs and the heuristic 'PDF_SEO_LINK_FARM' point towards an attempt to host malicious content or redirect to phishing pages.

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://zajinet.ru/strik?utm_term=sample+gm+diet+plan+day+4
