T1059.007 JavaScript
The PDF contains a large number of external links, with one heuristic specifically identifying a 'PDF_SEO_LINK_FARM'. The embedded URL 'https://trafficel.ru/123?utm_term=mike+scott+waterboys+twitter' is suspicious and likely part of a phishing or SEO spam campaign. ClamAV also detected this file as 'Pdf.Phishing.Trojan'. No scripts were extracted, but the overall structure suggests a malicious document intended to redirect users.

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://trafficel.ru/123?utm_term=mike+scott+waterboys+twitter
