T1059.007 JavaScript
The file is a PDF document that contains an embedded URL, identified as malicious by ClamAV and ML classifiers. The document body, though heavily obfuscated, suggests a lure related to an audiobook. The presence of an external URI and the high risk score indicate a phishing or malware distribution attempt, likely delivered as a spearphishing attachment.

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://zajinet.ru/123?utm_term=the+late+great+planet+earth+audiobook PDF link annotation
