The PDF document contains an embedded URI pointing to a malicious domain, identified by ClamAV as Pdf.Phishing.Trojan. The ML classifier also strongly flagged this PDF as malicious. The document body, though heavily obfuscated, suggests a lure related to an 'answer key', likely intended to trick users into visiting the malicious URL for further compromise.

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://midufefew.ru/wix?keyword=gizmo+plate+tectonics+answer+key
