T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many of which point to potentially malicious domains, as indicated by the 'PDF_SEO_LINK_FARM' and 'ML_NYX_PDF_MALICIOUS' heuristics. ClamAV also detected it as 'Pdf.Phishing.Trojan'. The embedded URLs suggest an attempt to redirect users to phishing or malware hosting sites, likely as part of a spearphishing campaign.

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://vilenefex.ru/strik?utm_term=how+long+to+do+brandt+daroff+exercises
