The PDF file was detected as malicious by ClamAV and an ML classifier, indicating a phishing or malware distribution attempt. It contains numerous external links, including one to 'zajinet.ru/strik', suggesting it's part of a link farm or SEO spam campaign designed to redirect users. The document body, though heavily obfuscated, contains text related to 'yeezy boost 350 v2', likely a lure to attract clicks.

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://zajinet.ru/strik?utm_term=what+size+to+get+yeezy+boost+350+v2
