T1059.007 JavaScript
The file is a PDF that contains a large number of external links, many of which point to PDFs hosted on various cloud storage services, suggesting a link farm or SEO manipulation tactic. The primary URL, 'https://jottigo.ru/strik?utm_term=english+idioms+and+phrases+with+meanings+in+hindi+pdf', is suspicious and likely leads to a phishing or malware distribution site. ClamAV and ML classifiers also flagged this PDF as malicious, specifically as a phishing trojan.

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://jottigo.ru/strik?utm_term=english+idioms+and+phrases+with+meanings+in+hindi+pdf PDF link annotation
