T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, a technique often used in SEO poisoning or phishing campaigns to redirect users to malicious sites. The heuristic PDF_SEO_LINK_FARM specifically indicates a mass of external links, with one pointing to 'https://s3.amazonaws.com/boduxatavepe/kabar.pdf'. The embedded URL 'https://jacksth.ru/wix?keyword=cub+scout+handbooks+online' suggests a lure related to online handbooks. ClamAV detection as 'Pdf.Phishing.Trojan' further supports a malicious classification.

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://jacksth.ru/wix?keyword=cub+scout+handbooks+online
