T1059.007 JavaScript
This PDF document was flagged as malicious by an ML classifier and contains a large number of external links, suggesting a link farm or distribution mechanism. The primary URL, https://trafftec.ru/strik?utm_term=entrepreneurship+online+courses+stanford, appears to be a lure. While no scripts were explicitly extracted, the PDF structure and heuristic firings indicate malicious intent, likely related to distributing further content or SEO abuse.

Heuristics 4
-
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://trafftec.ru/strik?utm_term=entrepreneurship+online+courses+stanford
