T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged by a machine learning classifier and ClamAV as malicious, specifically as a phishing trojan. It contains an external URI pointing to a URL that mimics a free book download, suggesting a social engineering lure. While no scripts were directly extracted, the presence of embedded URLs and the nature of the detection indicate a phishing attempt designed to trick users into downloading further malicious content.

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/award?keyword=knowledge+encyclopedia+book+free+download+pdf
