T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, a technique often used in SEO link farms to manipulate search engine rankings or to host malicious content. The presence of a ClamAV detection for 'Pdf.Phishing.Trojan' and a high ML classifier score strongly indicate malicious intent. The primary URL, 'https://mezovuduw.ru/wix?keyword=aluminum+design+manual+2010+free+download', suggests a lure related to downloading a design manual, which is a common phishing tactic.

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://mezovuduw.ru/wix?keyword=aluminum+design+manual+2010+free+download
