The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://gettraff.ru/aws?utm_term=dead+air+stalker'. The ML classifier also strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the nature of the redirector suggests an attempt to lure the user to a malicious site, consistent with phishing or malware delivery.

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.
