T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with several pointing to disposable hosting and potentially malicious domains, as indicated by the 'PDF_SEO_DISPOSABLE_LINK_FARM' and 'ML_NYX_PDF_MALICIOUS' heuristics. The ClamAV detection 'Pdf.Phishing.Trojan' further supports a malicious classification. The document body, though heavily obfuscated, suggests a lure related to educational materials to drive users to these external sites.

Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARMSmall PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.

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://dugedepap.ru/award?keyword=coordinate+geometry+class+11+iit+jee+pdf PDF link annotation
