T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with one specifically pointing to a URL that appears to be a search result for free software. This suggests a phishing or malware distribution attempt. The presence of a large number of external links, including a link farm heuristic, indicates an attempt to direct users to external resources, potentially for malicious purposes. ClamAV detection further supports the malicious classification.

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://trafftec.ru/strik?utm_term=photo+mixer+free+download+windows+7+full+version
