T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by ML classifiers and ClamAV, with a high risk score. It contains embedded URLs, one of which, 'https://zajinet.ru/award?keyword=medical+fitness+certificate+form+pdf', is presented in the document body as a lure for a 'medical fitness certificate form'. While no scripts were explicitly extracted, the presence of multiple external URLs suggests a phishing or malware distribution attempt, likely initiated via 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/award?keyword=medical+fitness+certificate+form+pdf
