T1059.007 JavaScript
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ggtraff.ru'. This indicates an attempt to lure the user to a potentially harmful website. The ML classifier also strongly flagged this PDF as malicious, and ClamAV detected it as a phishing trojan. While no scripts were explicitly extracted, the nature of the redirector suggests a phishing or malware delivery 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.
