T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, with one pointing to a suspicious domain 'coretry.ru'. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, suggesting a link farm or phishing attempt. ClamAV detection as 'Pdf.Phishing.Trojan' further supports malicious intent. No scripts were extracted, but the embedded URLs and link farm behavior are strong indicators of a phishing or malware distribution campaign.

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://coretry.ru/pbw?utm_term=mod+don%2527t+feed+the+bears+lyrics PDF link annotation
