T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, which is indicative of a link farm or phishing attempt. The ClamAV detection and ML classifier further support its malicious nature. The primary IOC is the URL 'https://trafffi.ru/123?utm_term=fortresscraft+evolved+wikia', which is likely the intended destination for the user.

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=fortresscraft+evolved+wikia
