This PDF file was flagged as malicious by ClamAV and an ML classifier, indicating a phishing or trojan threat. It contains a large number of external links, many of which point to PDFs hosted on services like sqhk.co, suggesting a link farm or redirection scheme. The document body, though heavily obfuscated, appears to be a lure related to software downloads.

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://traffking.ru/strik?utm_term=best+free+music+download+app+for+windows+10
