T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, a common tactic for link farms or phishing lures. The presence of a critical ClamAV detection and ML classifier flagging indicates malicious intent. The primary URL, https://trafffi.ru/123?keyword=pnb+rock+trapstar+turnt+popstar+download, is likely the malicious payload delivery point, disguised as a download link.

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://trafffi.ru/123?keyword=pnb+rock+trapstar+turnt+popstar+download
