T1059.007 JavaScript
This PDF file was flagged by multiple heuristics as malicious, including a critical finding for a PDF link farm containing numerous external links. The ML classifier also assigned a high probability of maliciousness. The embedded URLs suggest a phishing or SEO manipulation campaign, likely intended to redirect users to malicious sites. No scripts were extracted, but the presence of many external links indicates a high likelihood of further malicious activity.

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://seumenha.ru/strik?utm_term=uci+2020+decision+date
