T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a link to a known malicious redirector, which is also flagged by ClamAV and a machine learning classifier as malicious. The document body, though heavily obfuscated, contains text related to car sales, suggesting a phishing lure. No scripts were extracted, but the presence of a malicious URL strongly indicates a phishing attempt.

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.
