T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with a significant number pointing to potentially malicious domains, as indicated by the 'PDF_SEO_LINK_FARM' heuristic. The ClamAV detection and ML classifier strongly suggest malicious intent, specifically phishing. The embedded URL 'https://vilenefex.ru/strik?utm_term=hi-point+9mm+carbine+for+sale+canada' and the link farm URL 'http://docita.fun/499912157327cpxh.pdf' are the highest priority IOCs for potential redirection to malware or phishing sites.

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=hi-point+9mm+carbine+for+sale+canada
