T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a mass external link farm, with numerous URLs pointing to other PDF documents, suggesting a phishing or SEO poisoning campaign. The primary URL, 'https://traffnew.ru/aws?utm_term=arkabutla+lake+fishing+guides', appears to be a lure to disguise the malicious intent. ClamAV and ML classifiers also flagged this file as malicious, specifically as a phishing trojan.

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=arkabutla+lake+fishing+guides
