T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous embedded links, with one prominent URL pointing to 'midufefew.ru', suggesting a phishing or malicious content delivery attempt. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, likely for SEO manipulation or to distribute further payloads. ClamAV detection as 'Pdf.Phishing.Trojan' strongly supports a malicious classification.

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://midufefew.ru/aws?utm_term=night+owl+dvr+ddns+configuration
