T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, a technique often used for SEO poisoning or phishing. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external PDF links, suggesting a malicious intent to redirect users to potentially harmful sites. The presence of URLs like 'https://dugedepap.ru/strik' and 'https://kobizixudowizeb.weebly.com/uploads/1/3/4/4/134402546/zoxoxewolavuzuf-jefojini-wufelazuw-wisamoxop.pdf' further supports this, as they are likely part of a malicious campaign. Although no scripts were explicitly extracted, the PDF structure and heuristics strongly suggest a phishing or malware distribution attempt.

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://dugedepap.ru/strik?utm_term=asian+art+dorinda+neave+pdf+free+download PDF link annotation
