T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or SEO spamming operation. One prominent external URI points to 'https://trafficel.ru/123?utm_term=csx+railroad+jobs+alabama', which is presented in a context that mimics job search results. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the nature of the link farm and the embedded URLs suggest an attempt to redirect users to malicious or spam content, potentially for phishing or ad fraud.

-
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://trafficel.ru/123?utm_term=csx+railroad+jobs+alabama
