T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file is identified as malicious by multiple heuristics, including a critical ClamAV detection and an ML classifier. It exhibits characteristics of a PDF link farm, containing numerous external links, one of which is to zajinet.ru. The document body is heavily obfuscated and appears to be a lure related to an 'alkaline diet list printable'. The presence of embedded external links suggests an attempt to redirect users to potentially harmful content or for SEO manipulation.

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://zajinet.ru/wb?keyword=alkaline%20diet%20list%20printable
