T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with one prominent link pointing to 'xajibur.ru'. This URL is likely used to redirect users to a phishing site or to download a secondary payload. The ClamAV detection and ML classifier strongly indicate malicious intent, specifically related to phishing. The document body, though heavily obfuscated, contains metadata suggesting it was generated by wkhtmltopdf, a tool often used to create documents for SEO link farms, which are frequently abused for malicious purposes.

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://xajibur.ru/strik?utm_term=corte+bob+corto+cabello+rizado
