This PDF file was flagged as malicious by ClamAV and an ML classifier. It contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic, with one prominent URL being https://traffset.ru/123?utm_term=jack+daniels+wood+chips. The document body is heavily obfuscated and appears to be generated content, likely intended to mask the malicious intent of directing users to potentially harmful external sites.

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://traffset.ru/123?utm_term=jack+daniels+wood+chips
