T1204.002 Malicious Link
The PDF file was detected as malicious by ClamAV and an ML classifier, exhibiting characteristics of a phishing or SEO link farm. It contains numerous external links, with a primary URL pointing to 'traffnew.ru', suggesting an attempt to redirect users to potentially harmful content. The presence of a link farm heuristic further supports the conclusion that the document's primary purpose is to drive traffic to external sites.

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://traffnew.ru/123?utm_term=hawaii+vehicle+registration
