T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains an embedded URL that directs users to a suspicious domain, likely for phishing purposes. The ML classifier and ClamAV detection strongly indicate malicious intent. Although no scripts were explicitly extracted, the presence of an external URI and the overall classification suggest it's designed to trick users into visiting a malicious site, potentially leading to further compromise.

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://catamma.ru/pbw?utm_term=cubes+and+dice+-+non+verbal+reasoning+questions+and+answers+pdf
