T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a large number of external links, many of which point to URLs that appear to be part of a link farm. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external PDF links, suggesting an attempt to manipulate search engine results or drive traffic to specific sites. The embedded URL 'https://resalured.ru/strik?utm_term=throne+of+glass+series+order+to+read' further supports this, as it is presented in a context related to a popular book series, likely as a lure. ClamAV detection and ML classification confirm the malicious nature of the file.

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://resalured.ru/strik?utm_term=throne+of+glass+series+order+to+read
