The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'traffmen.ru'. ML classification and ClamAV also strongly indicate maliciousness. The embedded URL is the primary indicator of compromise, likely serving as a lure for phishing or to download a secondary payload.

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.
