T1059.007 JavaScript
This PDF document contains a large number of external links, many of which point to other PDF files, suggesting a link farm or redirection mechanism. The primary URL, 'https://smidgel.ru/pbw?utm_term=the+lesson+of+the+kaibab+answers+key+pdf', is presented as a lure to entice users to click, likely leading to a phishing site or a download of further malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, consistent with 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://smidgel.ru/pbw?utm_term=the+lesson+of+the+kaibab+answers+key+pdf
