T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, with a critical heuristic identifying it as a 'PDF_SEO_LINK_FARM'. One of the primary external URIs, 'https://resalured.ru/strik?utm_term=what+are+the+negative+personality+traits', is flagged as suspicious. The ML classifier and ClamAV also strongly indicate maliciousness, classifying it as a phishing trojan. While no scripts were explicitly extracted, the structure and heuristics suggest an attempt to redirect users to malicious content.

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://resalured.ru/strik?utm_term=what+are+the+negative+personality+traits PDF link annotation
