T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, with one heuristic specifically identifying a 'PDF_SEO_LINK_FARM' indicating a large number of outbound links. The document body, though heavily obfuscated, suggests a lure related to 'business law book pdf'. The presence of multiple unknown reputation URLs, including one directly related to the document's apparent theme, strongly suggests a phishing or redirection attempt. While no scripts were explicitly extracted, the PDF structure and link farm heuristic point towards malicious intent.

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://dugedepap.ru/award?keyword=business+law+book+pdf+for+b.+com
