T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, a common tactic for SEO link farms and phishing. One prominent URL, 'https://midufefew.ru/award?keyword=number+theory+with+computer+applications+pdf', is directly linked to the document's apparent purpose of luring users to a malicious site. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution.

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://midufefew.ru/award?keyword=number+theory+with+computer+applications+pdf
