T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, a common tactic for SEO poisoning and phishing. The presence of a URL pointing to 'traffine.ru' with a query related to downloading software, combined with ClamAV detection and ML classification, strongly suggests a malicious intent to trick users into downloading malware. While no scripts were explicitly extracted, the PDF structure and embedded links are indicative of a phishing or malware distribution lure.

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://traffine.ru/123?utm_term=tubemate+apk+file+download+latest+version
