T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, with one pointing to a suspicious domain 'midufefew.ru'. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, suggesting a link farm or phishing attempt. ClamAV also detected this as 'Pdf.Phishing.Trojan'. The document body, though heavily obfuscated, appears to be a lure related to a book summary, aligning with phishing tactics.

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. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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://midufefew.ru/strik?utm_term=ensayo+del+libro+la+meta+de+eliyahu+goldratt PDF link annotation
