T1059.007 JavaScript
The PDF document contains a heuristic firing for a link farm, indicating it is designed to direct users to numerous external URLs. One of these URLs, https://kuzutuzo.ru/strik?utm_term=hogwarts+extreme+sorting+quiz+answers, is presented as a lure for a Hogwarts quiz. The ClamAV detection and ML classifier strongly suggest malicious intent, likely related to phishing or malware distribution via the linked 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://kuzutuzo.ru/strik?utm_term=hogwarts+extreme+sorting+quiz+answers
