T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF containing numerous external links, with one heuristic specifically identifying it as a 'PDF_SEO_LINK_FARM'. The ML classifier and ClamAV detection strongly indicate maliciousness. The embedded URL 'https://trafffe.ru/123?utm_term=mma+training+guide' is the most suspicious IOC, likely serving as a landing page for a phishing attack or to download further malicious content.

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://trafffe.ru/123?utm_term=mma+training+guide
