T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or phishing attempt. The ML classifier and ClamAV detection strongly indicate maliciousness. The embedded URLs, such as 'https://vilenefex.ru/award?keyword=body+language+book+in+punjabi+pdf', are likely used to redirect users to malicious sites or download further payloads.

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.

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=body+language+book+in+punjabi+pdf
