T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document flagged as malicious by ML classifiers and ClamAV. It contains an embedded URI pointing to 'https://jacksth.ru/award?keyword=castilian+language+pdf', which is a strong indicator of a phishing or malware distribution attempt. The document body is heavily obfuscated, preventing a clear understanding of its specific lure, but the presence of the external URL and the malware verdict strongly suggest malicious intent.

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://jacksth.ru/award?keyword=castilian+language+pdf
