T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged by multiple heuristics, including ClamAV and an ML classifier, indicating malicious content. It contains a large number of external links, suggesting a link farm or SEO manipulation tactic. The embedded URLs point to various PDF files, potentially serving as lures or part of a phishing campaign. No scripts were extracted, but the presence of external links and the 'Pdf.Phishing.Trojan' ClamAV signature strongly suggest a phishing or malicious redirection intent.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host.

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://bologen.ru/strik?utm_term=english+grammar+book+betty+azar+pdf
