T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, a common tactic for SEO poisoning and phishing. The heuristic PDF_SEO_LINK_FARM indicates a large number of links, and one specific URL, https://vilenefex.ru/strik?utm_term=liftmaster+error+codes+10+flashes, is directly associated with a search query, suggesting a lure. ClamAV also identified this as Pdf.Phishing.Trojan. The document body is heavily obfuscated and unreadable, but the presence of embedded URLs and the overall structure point towards a malicious intent to redirect users to potentially harmful sites.

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://vilenefex.ru/strik?utm_term=liftmaster+error+codes+10+flashes PDF link annotation
