T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many pointing to domains associated with SEO spam or phishing. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, and the ClamAV detection as 'Pdf.Phishing.Trojan' strongly suggests malicious intent. While no scripts were explicitly extracted, the PDF structure and numerous external URLs point towards a malicious campaign, likely involving spearphishing.

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://jacksth.ru/wix?keyword=oxford+guide+to+english+grammar+pdf
