T1059.007 JavaScript
The file is identified as malicious by ML classification and ClamAV, with a specific ClamAV detection name indicating a phishing trojan. An external URI pointing to 'trafffi.ru' was extracted, suggesting a phishing lure. The document body, though heavily obfuscated, contains text related to message export and the authoring application 'wkhtmltopdf', which could be used to disguise 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://trafffi.ru/123?utm_term=msg+to+vcf+export PDF link annotation
