T1059.007 JavaScript
The PDF contains numerous external links, with one heuristic specifically identifying a 'PDF link farm' suggesting a large-scale distribution effort. The document body, though heavily obfuscated, contains a question about WW1 alliances, likely a lure to encourage clicks on the embedded malicious URLs. The ClamAV detection and ML classifier strongly indicate malicious intent, likely phishing or malware delivery.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host.

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://vilenefex.ru/strik?utm_term=what+were+the+2+alliances+in+ww1
