T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by multiple heuristics, including ClamAV and an ML classifier, with a critical finding of a PDF link farm. The embedded URL `https://jacksth.ru/strik?utm_term=propiedades+quimicas+de+los+alquenos+hidratacion` is a primary indicator of malicious intent, likely serving as a redirect to a phishing or malware distribution site. The PDF structure and the presence of numerous external links suggest an attempt to manipulate search engine rankings or 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://jacksth.ru/strik?utm_term=propiedades+quimicas+de+los+alquenos+hidratacion
