T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, including one to 'traffnew.ru/strik', suggesting a phishing or redirection attempt. The 'PDF_SEO_LINK_FARM' heuristic indicates a large number of external links, likely for SEO manipulation or to host malicious content. ClamAV detection as 'Pdf.Phishing.Trojan' further supports a malicious classification. No scripts were extracted, but the presence of multiple external URLs points to a likely attempt to redirect the user 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://traffnew.ru/strik?utm_term=ap+psychology+2004+multiple+choice+answers
