The PDF file contains an embedded URL that points to a suspicious domain, identified by ClamAV as Pdf.Phishing.Trojan.

The presence of an external URI and the ML classifier's high confidence score indicate a malicious intent, likely to redirect the user to a phishing site or download further malicious content.

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.
