T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic, suggesting a malicious intent to manipulate search engine results or redirect users to potentially harmful content. The ClamAV detection and ML classifier further indicate maliciousness, classifying it as a 'Pdf.Phishing.Trojan'. While no scripts were explicitly extracted, the presence of numerous external links points towards a phishing or content-serving attack 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://xezojetit.ru/award?keyword=brexit+deal+summary+pdf
