T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'https://cctraff.ru/123?utm_term=los+angeles+clippers+subreddit'. This URL is likely part of a phishing or malware distribution campaign. The ML classifier also strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of a malicious URL within a PDF document strongly suggests an attempt to trick the user into visiting a harmful site, consistent with spearphishing.

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.
