T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF document contains a large number of embedded external links, a technique often used for SEO manipulation or to redirect users to malicious sites. The ClamAV detection and ML classifier strongly indicate malicious intent, specifically classifying it as Pdf.Phishing.Trojan. No scripts were extracted, but the presence of numerous links suggests a phishing or content-farming attack pattern. The primary IOC is the initial external URI found.

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://bologen.ru/strik?utm_term=chapter+4+integumentary+system+worksheet+answers PDF link annotation
