The PDF contains an embedded URL that redirects to a malicious domain, likely intended for phishing or malware distribution. ClamAV and ML classifiers strongly indicate maliciousness. The document body, though heavily obfuscated, appears to contain keywords related to a video game, suggesting a lure to entice users to click the malicious link.

External URI info PDF_URI

PDF contains an external URL action
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL

The 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_URL

One 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.
