T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many of which are disguised as search results for popular content like movies. The heuristic 'PDF_SEO_LINK_FARM' indicates a deliberate attempt to create a link farm, and the 'ML_NYX_PDF_MALICIOUS' classifier strongly suggests malicious intent. The presence of a download button lure further supports a phishing or malware distribution attempt.

Heuristics 6
-
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.

-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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=black+hawk+down+full+movie+download+fzmovies
