T1059.007 JavaScript
The PDF file contains a large number of external links, many of which are hosted on dynamic DNS services and appear to be part of a link farm. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external PDF links, suggesting a malicious intent to redirect users to potentially harmful sites. The ClamAV detection and ML classifier further support its malicious nature, likely for 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://traffking.ru/strik?utm_term=kill+the+plumber+2+game
