T1059.007 JavaScript
The file is identified as a malicious PDF by multiple heuristics and a machine learning classifier. It contains numerous external links, with one pointing to 'vilenefex.ru', suggesting a phishing or redirection attempt. The presence of PDF-specific heuristics like 'PDF_URI' and 'PDF_SEO_LINK_FARM' indicates the document's primary function is to host and link to external content, likely malicious.

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/123?utm_term=ocean+basket+cyprus+menu+pdf
