T1059.007 JavaScript
The PDF contains a link to a known malicious redirector, traffmen.ru, which is disguised as an algebra worksheet. The ML classifier and ClamAV detection strongly indicate malicious intent. The embedded URL likely serves as a lure to download a second-stage 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.
