T1059.007 JavaScript
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://traffmen.ru/aws?utm_term=plataforma+areandina+canvas'. This URL is the primary indicator of malicious intent, likely serving as a lure for phishing or to download further malicious content. The ML classifier and ClamAV also strongly indicate maliciousness.

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.
