T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF containing an embedded URL that points to a suspicious domain, identified by heuristics as potentially malicious and flagged by a machine learning classifier. The ClamAV detection further confirms its malicious nature, specifically classifying it as a phishing trojan. The document body, though heavily obfuscated, contains references to 'wkhtmltopdf' and a date, suggesting it might be a generated document used as a lure.

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=bowditch+volume+2+1981+pdf PDF link annotation
