The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://traffmen.ru/123?utm_term=d%2526d+beyond+stirge'. This URL is identified as malicious and is likely used to lure victims to a phishing or malware-hosting site. The ML classifier and ClamAV also strongly indicate maliciousness, supporting the classification as a phishing or malware distribution vector.

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.
