T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a link to a known malicious redirector, gettraff.ru, which is a strong indicator of malicious intent. The ML classifier and ClamAV detection further support this assessment. The document body, though heavily obfuscated, appears to reference a book sale, suggesting a social engineering lure to entice users to click the malicious link.

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.
