T1059.007 JavaScript
The PDF file was identified as malicious by ClamAV and an ML classifier, with heuristics indicating it contains a link farm and an external URI. The document body, though heavily obfuscated, suggests a lure related to 'Health psychology 9th edition pdf'. The presence of numerous Weebly and Strikingly hosted PDF links points towards a campaign distributing malicious content, likely for phishing or malware delivery.

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/strik?utm_term=health+psychology+9th+edition+pdf
