T1059.007 JavaScript
The PDF contains numerous external links, indicative of a link farm or phishing campaign, as suggested by the 'PDF_SEO_LINK_FARM' heuristic. The ML classifier and ClamAV detection strongly indicate malicious intent, specifically classifying it as a phishing trojan. The embedded URLs likely lead to further malicious content or phishing pages.

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://soxebez.ru/award?keyword=tecnicas+de+afrontamiento+pdf
