T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains numerous external links, with a critical heuristic identifying it as a link farm for SEO purposes, likely a phishing lure. The primary malicious URL identified is https://gimoguvi.ru/wix?keyword=c%25C3%25B4+d%25C3%25A2u+8+tu%25E1%25BB%2595i+tr%25E1%25BB%258Dn+b%25E1%25BB%2599+ph%25E1%25BA%25A7n+4. ClamAV detection further confirms its malicious nature as Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0. While no scripts were explicitly extracted, the structure and heuristics strongly suggest an intent to redirect users to malicious 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.
-
Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINKPDF embeds an image with little or no body text and a clickable link to a multi-word utm_term / FeedBurner-proxied SEO redirector — the 'free ebook / solution-manual / document download' phishing family that ranks for natural-language search queries and routes the user into a payload/redirect chain. The PDF carries no exploit; the risk is the linked destination. Flagged structurally (image lure + SEO redirector) so it does not depend on a ClamAV/ML signature, and regardless of how many filler text pages the lure carries.

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://gimoguvi.ru/wix?keyword=c%25C3%25B4+d%25C3%25A2u+8+tu%25E1%25BB%2595i+tr%25E1%25BB%258Dn+b%25E1%25BB%2599+ph%25E1%25BA%25A7n+4 PDF link annotation
