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 redirect users to malicious websites. The heuristic 'PDF_SEO_LINK_FARM' specifically identifies this behavior, indicating a high likelihood of malicious intent. The embedded URLs, such as https://jacksth.ru/strik?utm_term=monroe%2527s+motivated+sequence+outline+example, are likely part of this redirection scheme.

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=monroe%2527s+motivated+sequence+outline+example
