T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or phishing campaign. The primary external URL, 'https://trafffi.ru/123?utm_term=armadillo+lizard+for+sale+uk', is likely a lure. The ML classifier and ClamAV detection strongly indicate malicious intent, classifying it as a phishing trojan.

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=armadillo+lizard+for+sale+uk
