T1566.001 Spearphishing Attachment
The PDF contains an embedded URI pointing to 'wastran.ru', which is flagged as malicious. ClamAV also detected this file as 'Pdf.Phishing.Trojan'. The ML classifier strongly indicates maliciousness. While no scripts were explicitly extracted, the presence of an external URI in a malicious PDF suggests an attempt to redirect the user to a harmful site, likely for phishing or to download further malware.

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://wastran.ru/square?utm_term=dungeons+and+dragons+jeremy+irons
