T1059.007 JavaScript
The file is a PDF that uses the guise of providing 'Adirondack chair plans' to host a large number of external links, a technique often used for SEO manipulation or to distribute malware. ClamAV and ML classifiers identified it as malicious, specifically a phishing or trojan variant. While no scripts were directly extracted, the PDF structure and embedded URLs suggest an attempt to redirect users to potentially harmful content.

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.
