T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF document functions as a link farm, presenting numerous external URLs that are likely intended to lead users to malicious content, such as pirated software downloads that may contain malware. The PDF_SEO_LINK_FARM and PDF_SEO_DISPOSABLE_LINK_FARM heuristics indicate a large number of links hosted on disposable domains, and the ML classifier and ClamAV detection strongly suggest malicious intent. The embedded URLs, such as 'https://baarspo.ru/strik?utm_term=coreldraw+x8+free+download+full+version+with+crack+kickass', reinforce the lure of pirated software.

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.
-
Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARMSmall PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.

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://baarspo.ru/strik?utm_term=coreldraw+x8+free+download+full+version+with+crack+kickass PDF link annotation
