T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, identified as a "PDF_SEO_LINK_FARM" heuristic, pointing to various PDF files hosted on different domains. One prominent URL, "https://traffnew.ru/aws?utm_term=javadoc+syntax+cheat+sheet", is embedded within the document's text and appears to be a lure. ClamAV detection as "Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0" and a high ML classifier score further indicate malicious intent, likely related to phishing or redirecting users to malicious sites.

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://traffnew.ru/aws?utm_term=javadoc+syntax+cheat+sheet
