T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, many of which point to suspicious domains and are likely part of a link farm for SEO manipulation. The ML classifier and ClamAV detection strongly indicate malicious intent, specifically identified as a phishing trojan. The embedded URLs suggest the document's primary purpose is to redirect users to malicious websites, potentially for phishing or to download further payloads.

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. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.

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/wix?keyword=governor+wentworth+regional+school+district+jobs PDF link annotation
