This PDF file was identified as malicious by ClamAV and an ML classifier, indicating a high likelihood of malicious intent. The PDF contains a large number of external links, many pointing to potentially malicious domains, suggesting it functions as a link farm or a lure for phishing. The embedded URLs and the heuristic 'PDF_SEO_LINK_FARM' strongly suggest the document's purpose is to redirect users to malicious sites, likely for malware distribution or credential harvesting.

External URI info PDF_URIPDF contains an external URL action
-
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://seumenha.ru/strik?utm_term=11.s%25C4%25B1n%25C4%25B1f+kimya+ders+kitab%25C4%25B1+%25C3%25A7%25C3%25B6z%25C3%25BCmleri+e+kare+yay%25C4%25B1nlar%25C4%25B1
