T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF containing an embedded URI pointing to a suspicious domain, vilenefex.ru. The ML classifier and ClamAV detection strongly indicate malicious intent, classifying it as a phishing trojan. The PDF structure itself is also flagged for duplicate object bodies, a common obfuscation technique. The embedded URL is the primary indicator of a potential phishing or malware delivery attempt.

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://vilenefex.ru/award?keyword=pinzamiento+tardio+de+cordon+umbilical+pdf
