T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, indicative of an SEO spam or phishing campaign aiming to drive traffic to malicious sites. The presence of a download button lure and ClamAV detection as 'Pdf.Phishing.Trojan' strongly suggests malicious intent. While no scripts were explicitly extracted, the PDF structure and external links point towards a malicious workflow, likely involving the download of further malicious content.

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.

-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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://seumenha.ru/wix?keyword=blitzer+algebra+and+trigonometry+pdf
