T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by ClamAV and an ML classifier, with heuristics indicating it contains an embedded URI and uses an invoice/payment lure. The embedded URL, https://crophysi.ru/award?keyword=best+way+to+check+business+credit+report, is likely the primary objective, aiming to redirect the user to a malicious site. While no scripts were explicitly extracted, the PDF structure and detection names suggest it may leverage embedded JavaScript or exploit techniques to achieve its malicious goal.

-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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://crophysi.ru/award?keyword=best+way+to+check+business+credit+report
