T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many pointing to benign-looking documents, but also includes a link to 'traffking.ru', which is likely malicious. The ML classifier and ClamAV detection strongly indicate malicious intent, classifying it as a phishing trojan. The presence of embedded URLs and the PDF_SEO_LINK_FARM heuristic suggest the document is designed to redirect users to potentially harmful sites.

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://traffking.ru/123?utm_term=boneless+girl+unblocked
