T1059.007 JavaScript
The PDF contains a large number of external links, many of which point to potentially malicious domains, suggesting a link farm or phishing attempt. The heuristic PDF_SEO_LINK_FARM indicates a mass of external PDF links, and the ML classifier and ClamAV detection strongly suggest malicious intent. The primary malicious URL identified is https://nipisod.ru/strik?utm_term=the+legend+of+korra+turf+wars+portugues+pdf.

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://nipisod.ru/strik?utm_term=the+legend+of+korra+turf+wars+portugues+pdf
