T1059.007 JavaScript
This PDF file was flagged by multiple heuristics and an ML classifier as malicious, specifically as a phishing or trojan. It contains a large number of external links, many pointing to PDF files hosted on services like Weebly and sqhk.co, suggesting a link farm or SEO manipulation tactic. The primary URL, https://jacksth.ru/strik, is likely a redirection or landing page for a malicious campaign. No scripts were extracted, but the presence of numerous external links indicates an attempt to redirect the user to potentially harmful content.

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://jacksth.ru/strik?utm_term=what+are+the+elements+of+value+chain+analysis
