T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a heuristic indicating an external URI, which points to a suspicious domain 'jacksth.ru'. The document body, though heavily obfuscated, contains text related to 'country dance songs' and the authoring application 'wkhtmltopdf', suggesting a lure. ClamAV detection as 'Pdf.Phishing.Trojan' further supports its malicious nature, likely involving a phishing attempt to redirect users to the malicious URL.

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/strik?utm_term=country+dance+songs+2019+2+step
