T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a large number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic. One of these links, 'https://jacksth.ru/strik?utm_term=st+edwards+state+park+map', is directly embedded and likely serves as the primary lure. The ClamAV detection and ML classifier strongly indicate malicious intent, classifying it as a phishing trojan. While no scripts were explicitly extracted, the nature of the link farm suggests a potential for JavaScript execution or redirection to malicious sites.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host.

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=st+edwards+state+park+map
