T1059.007 JavaScript
The PDF contains a critical heuristic firing indicating it links to known malicious redirector infrastructure. The embedded URL 'https://ggtraff.ru/strik?keyword=mathematical+methods+for+physics+and+engineering' is the primary indicator of malicious intent. While no scripts were explicitly extracted, the PDF structure and the presence of numerous embedded URLs suggest an attempt to lure the user to a malicious site, likely for phishing or malware delivery. The ML classifier also strongly flagged this PDF as malicious.

Heuristics 3
-
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.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ggtraff.ru/strik?keyword=mathematical+methods+for+physics+and+engineering
