T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file was flagged by ClamAV as a phishing trojan and by an ML classifier as malicious. It contains numerous external URIs, many pointing to disposable domains, suggesting a link farm or phishing campaign. The presence of embedded URLs and the heuristic indicating a link farm on disposable hosting strongly suggest the document's purpose is to redirect users to malicious sites, likely for further exploitation or credential harvesting.

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://vilenefex.ru/strik?utm_term=tabla+de+equivalencias+de+unidades+de+medida+del+sistema+ingles PDF link annotation
