The PDF file contains numerous external links, including one pointing to 'trafffe.ru', which is indicative of a phishing or malware distribution campaign. The heuristic 'PDF_SEO_LINK_FARM' suggests a large number of links were embedded, likely to obscure malicious intent. The ML classifier and ClamAV detection strongly indicate malicious content, likely related to phishing.

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://trafffe.ru/aws?utm_term=baby+alive+doll+food+template
