T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous embedded URLs, many pointing to disposable domains and employing UTM parameters, indicative of a link farm or phishing lure. Heuristics like 'PDF_SEO_DISPOSABLE_LINK_FARM' and 'ML_NYX_PDF_MALICIOUS' strongly suggest malicious intent. ClamAV detection as 'Pdf.Phishing.Trojan' further confirms this. The document body, though heavily obfuscated, contains references to software and manuals, aligning with common phishing pretexts.

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://lozipotod.ru/strik?utm_term=skyrim+special+edition+skyui+not+loading PDF link annotation
