The PDF file was flagged by multiple heuristics as malicious, including a critical ClamAV detection and an ML classifier. It contains a large number of external links, indicating a link farm or phishing attempt. The document body, though heavily obfuscated, suggests a lure related to educational worksheets, which is a common tactic for phishing or malware distribution.

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://traffine.ru/strik?utm_term=graphing+coordinates+pictures+free+worksheets
