T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains numerous external links, many pointing to benign S3 buckets, but also includes a suspicious URL (xezojetit.ru) and a ClamAV detection for 'Pdf.Phishing.Trojan'. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, suggesting a link farm or redirection mechanism. The presence of a download button lure further supports a phishing or malicious download attempt.

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.

-
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://xezojetit.ru/123?utm_term=wall+street+journal+page+6
