T1059.007 JavaScript
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ggtraff.ru'. ML classification also strongly indicates maliciousness. While no scripts were extracted, the presence of a malicious URL suggests the document's primary purpose is to lure the user to a compromised site, likely as part of a phishing or malware delivery chain.

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
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.
