T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF that contains a large number of external links, many of which point to other PDFs. The primary URL, trafftec.ru, is likely used for phishing or to host a malicious payload. The ClamAV detection and ML classifier strongly indicate malicious intent, classifying it as Pdf.Phishing.Trojan. The embedded links suggest a link farm or SEO poisoning tactic to distribute 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://trafftec.ru/strik?utm_term=euroflex+monster+steam+booster+instructions
