T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document that contains an embedded URL. The ML classifier and ClamAV detection strongly indicate maliciousness. The embedded URL, https://kuzutuzo.ru/strik?utm_term=marshall+rosenberg+nonviolent+communication+summary, is likely used to redirect the user to a phishing or malware distribution site. No scripts were extracted, but the PDF structure and embedded URI are sufficient indicators of malicious intent.

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://kuzutuzo.ru/strik?utm_term=marshall+rosenberg+nonviolent+communication+summary
