T1059.007 JavaScript
This PDF file was flagged by multiple heuristics as malicious, including a critical ClamAV detection for a phishing trojan. The PDF contains a large number of external links, suggesting a link farm or a mechanism to redirect users to malicious sites. The ML classifier also strongly indicated maliciousness. The presence of embedded URLs and the PDF_SEO_LINK_FARM heuristic point towards an attempt to distribute further malicious content or phish users.

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://pelibifir.ru/strik?utm_term=mouse+guard+roleplaying+game+pdf
