Malware Insights
The PDF document was flagged by a machine learning classifier and contains a link to a known malicious redirector. The embedded URL, 'https://ttraff.ru/wix?keyword=%25D0%25BF%25D0%25B5%25D1%2581%25D0%25BD%25D0%25B8+%25D0%25BE+%25D0%25B4%25D0%25B5%25D1%2582%25D1%2581%25D1%2582%25D0%25B2%25D0%25B5+%25D1%2581%25D0%25BE%25D0%25B2%25D1%2580%25D0%25B5%25D0%25BC%25D0%25B5%25D0%25BD%25D0%25BD%25D1%258B%25D0%25B5+%25D1%2581%25D0%25BA%25D0%25B0%25D1%2587%25D0%25B0%25D1%2582%25D1%258C', is the primary indicator of malicious intent. This suggests the document is designed to lure users into clicking the link, which then redirects to a potentially harmful destination.

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://ttraff.ru/wix?keyword=%25D0%25BF%25D0%25B5%25D1%2581%25D0%25BD%25D0%25B8+%25D0%25BE+%25D0%25B4%25D0%25B5%25D1%2582%25D1%2581%25D1%2582%25D0%25B2%25D0%25B5+%25D1%2581%25D0%25BE%25D0%25B2%25D1%2580%25D0%25B5%25D0%25BC%25D0%25B5%25D0%25BD%25D0%25BD%25D1%258B%25D0%25B5+%25D1%2581%25D0%25BA%25D0%25B0%25D1%2587%25D0%25B0%25D1%2582%25D1%258C
